The HDD passport is the information that is sewn at the factory, which characterizes the HDD family and its individual features.
It includes a family name, model name, a unique serial number, an integrated microcode version, logical parameters (geometry), interface parameters and much more.
The passport is required to properly identify the device.
If the Winchesters passport for some reason is lost, the HDD becomes unsuitable, because no program can use it for its intended purpose.
The passport is given when the key is pressed.
That's what we get from there (from top to bottom):
The full name of the model and the version of the built-in microcode;
. Serial number HDD;
. Number of available physical sectors (LBA);
. The volume of the disk in bytes;
. CHS parameters - number of cylinders, logical heads, sectors (relevant only for hard drives< 8,4 Гб).
. Smart. (status).
Enabled / Disabled - Displays whether SMART monitoring is enabled in the drive itself.
. Errlog. - Internal error logging.
. SelfTest. - Internal samotest (usually it is a surface test at a time when it does not appeal from outside).
If something from this is present in the drive, "[...] Present" will appear in the passport.
Keep in mind that on some hard drives, samystet can be disconnected in the passport, but really attend and work.
. Disk cache state.
The program makes an attempt to determine its size if it fails, reports "Unknown Size";
. Look Ahead. - Pre-election of reading.
May be turned on or off.
The disconnected pre-election indicates that or the hard drive is very old (does not support this function, or it is disabled with utilities / merchandise).
Winchester with a disconnected pre-election works very slowly, and usually it is immediately noticeable when working with files.
. Write. - Recording caching.
Exercises a deferred buffer recording to disk to speed up file operations.
May be turned on or off.
All modern hard drives are incorporated by default.
. Supported modes. This is the most interesting part of the passport.
It indicates which technical capabilities of this HDD model.
Here is the decryption of cuts:
. . HPA. - Host Protected Area: Winchester supports the possibility of changing physical volume.
. . Chs. - Cylinder / Head / Sector: Disk space addressing mode (occurring from FDD and first HDD drives), which allows you to contact separately to the heads, sectors and tracks.
In modern drives, logical CHS geometry is left for compatibility with old programs and BIOS.
. . LBA - Logical Block Addressing: Winchester supports addressing logical blocks, which is a de facto standard for modern HDD, OS and BIOS.
. . Pio. - PROGRAMMABLE INPUT / OUTPUT: Software input output, data exchange mode between Winchester and rAMimplemented with the participation of the Central PC processor.
It is characterized by simplicity of sales, reliability and versatility, but takes out processor time, which makes this mode unsuitable for multi-diplocked systems.
. . DMA - Direct Memory Access: Winchester supports direct access to memory, which allows you to unload cPU PC when exchanging disk.
As well as LBA, this mode is the norm, and not an exception for modern HDD.
In brackets are limited modes in which the hard drive can use DMA.
. . AAM. - Automatic Acoustic Management: Winchester allows you to programmatically control the level of acoustic noise.
This is achieved by changing the positioning speed of the heads.
. . APM. - Advanced Power Management: Winchester has built-in power management tools, which allows the system more economical and, in some cases, improve the reliability of the screw (due to smaller heat and parking of the heads).
For desktop systems is lowactively.
. . DLMC. - Download Microcode: Winchester allows you to update the "firmware" by loading an external microcode (applied by HDD manufacturers and branded PCs as indgisted firmware).
. . FLC - Flush Cache: Winchester supports forced cache reset to disk.
Probably, this command is designed to reduce the risk of data loss with a sudden power outage.
. . SMS. - SET MAX Security Support: Laziness to describe this garbage.
If you are interested, read the ATA standard.
. . DCO. - Device Configuration Overlay: Winchester supports the configuration of the set of some functions at the request of the user.
These include switching on and off SMART, support for addressing 48 bits, AAM, change of limit modes DMA, etc. (See also section "Restoring a disk configuration").
. Current Aam Value: The current value of the set noise level. 128 means that the minimum level, 0 maximum.
The program allows you to change this value arbitrarily, adjusting the noise.
AAM status is remembered even after turning off the power.
Nearby is the value recommended by the manufacturer.
. Current APM Value: The current value of the power saving mode.
As with AAM, 128 means minimal power consumption, 0 maximum.
In Winchesters for desktop PC it is almost always equal to 0, mobile can have different values \u200b\u200bset by energy saving utilities.
Unfortunately, the APM value is not saved after turning off the power, so its adjustment is not provided in Victoria.
However, many branded utilities for HDD are able to switch the APM "forever" using technological commands.
. Current Power Mode.: Current power consumption mode.
Actually says whether this moment HDD shaft.
Convenient for quiet hard drives, the more program allows you to stop the shaft at any time.
. Security Erase Time.: The time for which the disk security subsystem is able to erase all the information and remove the password.
It is usually commensurate with the verification time, i.e. Information is erased without interface and with the highest possible speed.
Interestingly, some HDD models in the passport on this place are recorded 0.
In this case, the erase time on the screen is not displayed.
It will not be displayed in the absence of security options in the HDD tested.
. Security (status).
. . ON.: Winchester Passed ATA password (the presence of a password installed on the screw also indicates the PWD light bulb at the top of the screen);
. . Off: The hard drive is not set a password;
. . High, Maximum: The level of secrecy of the installed password (see chapter about passwords);
. . Frozen.: Winchester in the Freeze-Lock state (the password system works, but temporarily blocked);
. . Expired.: Password tried unsuccessfully shooting 5 times.
As a result, HDD blocked the password system until the power is turned off;
. . Locked.: The password is set, there is no access to information.
. . Unlocked: Winchester is open, there is access to information.
In this case, the password can be set if the HDD is temporarily open by the Unlock command.
. . Not Supported: Winchester has no system password protection.
6. Disk software reset
Performed key.
This operation stops internal hDD work (If it was engaged in processing a command or a scholarship) and brings the interface to the default state (cleans the registers after the previous command and makes readiness to take the next one).
We need to diagnose the drive, interrupting the dependent firmware of the hard drive, etc.
It is performed immediately after pressing the button.
It also works and directly during disk operations (for example, reading).
A sign of a successful reset will be the included indicator Amnf..
Removing the password on the hard disk and BIOS laptop It is a fairly common problem with which users often encounter. There are several ways (utilities) that can help remove the password. At the moment, many utilities are popular in solving this problem. To fix it this situation, you need to follow certain rules.
You will need

Most recently had to face a terrible situation. Winchester was born, though on the 8GB of just, but still this is also money (:
When you turn on the computer and define devices, stumbled on the hardware definition, the computer issues a message.
HDD Locked. Please Enther The Password
Introducing the problem, I found a lot of interesting information regarding wanted screws. After reading everything below, I did what is even lower (:
Solutions exist paid (expensive and 2 options with the preservation of information (more expensive) and without it - cheaper).
Wizard Passwords for HDD. Master ATA Password.
Contrary to widespread misconception, it is impossible to "wage" or "block" using a master password. Master password can only be changed. Master Password can unlock the drive in case the user password is forgotten, but it is possible only if the level of protection "High" was set. If the protection level is "Maximum", you can unlock the drive only knowing the user-password. If the protection level is "maximum", the User password is unknown, but the master password is known, then it is possible to unlock the drive with the destruction of all data using the Security Erase Unit ATA command. This is implemented in the MHDD (FASTERASE command), however, this procedure in MHDD works only with USER passwords.
Thus, the drive blocked with the level of protection "High" can be unlocked using either Master or password user. If the level of protection "Maximum", then unlock
The drive can only be using the password user or the master password, but with the destruction of all data.
Manufacturers install factory master passwords, and if they do not change them in advance, then they can be used to unlock a salary drive, whose protection level "HIGH".
You can install the User-password by submitting the PWD command to MHDD. This establishes the level of protection "HIGH". The ability to install another level in MHDD is not available for security reasons. Also, the entered password is displayed in the MHDD.log file. After installing the password, the drive must be turned off.
Unlocking the drive, savaged with the level of protection "High" is possible using a user or master password. If the password is unknown, then, in general, unlock the drive is impossible, although there are two ways:
1. If the password is not encrypted by the drive itself, it can be tried to read it from the surface using technological commands;
2. It is possible to unlock using specially designed methods.
If the password is known, then the order of unlocking the drive in MHDD is:
1. Submit the Unlock command, select the user password, and enter the password. This temporarily removes the storage lock (before power off).
2. Submit the DISPWD command, select the user password, and enter the password again. It completely removes blocking.
According to the ATA / ATAPI standard, you cannot suppress the DISPWD command, without unlocking the drive by the Unlock command.
If the password is unknown, and the protection level of "Maximum", then without special means it is not necessary. If the password is unknown, and the level of protection "HIGH", and the master password has not changed, that is, the ability to unlock the drive, knowing the factory master password.
List of famous Master passwords:
Winchesters Fujitsu: Thirty two spaces. In MHDD, you must enter 32 spaces to the password request.
Seagate Winchesters: The word "seagate" without quotes, with a capital letter, supplemented 25 spaces up to 32 simavols. In the MHDD to the password request, you must enter the word seagate, and then 25 spaces. Also, the Council from one of the site visitors: if the password does not fit - try to enter the word seagate and 25 points.
Winchesters Maxtor: The phrase "MAXTOR INIT Security Test Step" - the register is important! At the end of the phrase - one space. Password length - 31 symbol.
SAMSUNG Winchesters: 32 characters "T". In MHDD, you must enter 32 symbols T to the password request.
Winchesters Western Digital: The phrase "wdcwdcwdcwdcwdcwdcwd", without quotes.
IBM Winchesters:
DTTA series: "CED79ijufnatit", complemented by spaces up to 32 characters. In MHDD, you should enter the phrase given to the password request, and then 18 spaces.
DJNA Series: "von89ijufsunaj", complemented by spaces up to 32 characters. In MHDD, you should enter the phrase given to the password request, and then 18 spaces.
DPTA series: "von89ijufsunaj", complemented by spaces up to 32 characters. In MHDD, you should enter the phrase given to the password request, and then 18 spaces.
DTLA Series: "Ram00ijufotselet", complemented by spaces up to 32 characters. In the MHDD to the password request, you must enter the shown the phrase and then 16 spaces. http://www.ihdd.ru/mhdd.
Hitachi Winchesters, DK23AA, DK23BA, DK23CA series: Thirty-two spaces. In MHDD, you must enter 32 spaces to the password request.
Winchesters Toshiba., All Series: Thirty two spaces. In MHDD, you must enter 32 spaces to the password request.
Below are User-passwords installed in certain situations with various popular programs:
MHDD. Versions 3.x occurs when an internal error occurs: 32 letters "A" or 32 letters "B" (large Latin).
HDDL., happens with an unsuccessful attempt to quickly erasing: "Fuck".
HRT.: 32 characters with code 0. In order to enter such a password in MHDD, it is enough to press the password request ENTER.
HDD ERASE 4.0.: While cleaning the disk installs the IDRIVE password - it can be removed it!
That's just prog HDD ERASE 4.0. I got a screw, all because I was after the end of the Erise's ending, the car rebatched ...
Ata Password on a hard disk is usually put in two cases:
1. The user itself sets the password and forgets it (it is possible to put another user, or the child is quite by chance), but the fact remains the fact that someone pains a hard disk in a laptop or computer manually.
2. HAVE HAVE HAVE (HDD) or BIOS motherboard laptop sets a password to a storage device due to a system failure (such cases also have been). These failures occur usually due to electrical power problems.
So do not be surprised if you suddenly have your hard disk with any Siago: here two options see above.
In order to remove the ATA PASWORD from the Samsung hard disk in 5 minutes you need to produce several simple stepsis not completely difficult, but so that the password is cleared special program To remove it, which works very simply (you can get the program by making a request for its receipt on our website by reference. After receiving a request, I will send you a program to the specified mail or send a link to Yandex or Google cloud where the program will lie.) In I can't lay out free access to the program, it is very rare and closed, thanks in advance for understanding.
The program works for all major hard drive manufacturers:
Samsung, Hitachi, WD, Seagate - Checked personally (if you didn't manage the key from the first time, you may incorrectly entered the error code, try the key again should consist of 8 characters as in Fig. 4., when entering the code, the layout should Being in English, if it didn't work out the first time, try again and once again, usually no more than three times you need to hold this procedure to get the right key to unlock the hard disk.)
In order to remove / reset the ATA password from the hard disk, Figure 1, 2, 3. It is enough to turn on the laptop 3 times enter the wrong password and get a code that is generated by the system.
Next, run the program, the one that I threw you on your request on any other computer and enter the code that received the wrong password when entering three times. Figure 4.
The password reset program from the hard disk generates a discharge key. You enter this key instead of password on your locked hard drive and all! A storage device is unlocked, forever 😉 well, or until the next random password.
So we summarize:
1. Pass the program for resetting the hard disk password.
2. Pour the code (we enter the password is incorrect three times)
3. Will the code in the program and get the unlock key.
4. For the received key in the password input field - the password is reset.
As you can see a password reset procedure from a hard disk, it is very simple, you don't even need to pull out a hard disk, you do not need to disassemble anything, for no matter what batteries you do not need to climb (still it does not help). All you need is a special password discharge program on hard drives you can get from me.
Frequently often users set a password on HDD. However, this would not be a problem if people had not forgotten these most established codes. If you first encountered such a situation and do not know how to remove a password from a hard disk on a laptop, then this article is intended for you.
If you installed the code on the internal media and forgotten, then you cannot even load the OS installed on your PC. That is, the ability to use a laptop or a computer for direct purpose will be simply absent. In such a situation, the user remains only to delete the set password because there is no other access to the computer.
Online service
There are several ways to remove the password with HDD, and one of them is the famous online service "BIOS Password Removal for Laptops".
In order to get rid of forgot Code By using it, it is necessary:
- Enter it incorrectly 3 times (any combination of numbers or letters).
- After that, a special code should appear in the window.
- Copy the figures received.
- We introduce the same combination on the site, according to the above link.
After a few seconds after entering the combination of numbers in a specially reserved line, you will receive a code that will help reset the password from your drive.
It should be clarified that this program Suitable for all models and manufacturers of Winchesters (Seagate, Hitachi, Toshiba, WD, etc.). Moreover, it does not matter which operating system is installed on your computer or laptop, because This service is considered universal.
Bios.
You can only remove the password from the hard disk in the BIOS only if the cipher was originally installed via BIOS.
All you need to use the standard default settings option:
Thus, we dropped the password with HDD.
Second way
Next option - free utility MHDD, specially created for a variety of hard disk operations.
To begin, it is necessary to get acquainted with the scheme of the password protection of the drive:
- Winchester can have a high or maximum level protection.
- Using the MHDD application, you can set a user protection level.
- Master password installed by the manufacturer can only be changed.
- The application of the master password makes it possible to unlock the disk exclusively at a high level of protection.
- In the case of the maximum level of protection, the hard drive can be unlocked only if the user code is installed.
- If the maximum level of protection is set and there is no user password, you can unlock the drive only by destroying all data using the Security Erase Unit Ata command.
Given the above information to remove the password from the hard disk, follows:
Thus, you can extremely remove the previously forgotten cipher entered.
Third way
Also remove the password from the hard disk will help the program HDD_PW.exe (18Kb). In order to remove the code with it, you want to do the following:
- Find out the error code (when loading clicking F2 and enter the wrong combination of numbers three times, after which a special code appears on the screen)
- Run the MS-DOS application.
- Select the name of the utility in the window that opens.
- On the gap to enter the error code that has learned earlier and add via space 0.
- By pressing "input", several passwords will appear before you, one of which is necessarily suitable.
After entering the code, be sure to change it to the new and write down.
When implementing such steps on the 64-bit system, you may have some difficulties. The system can issue a mistake due to the inconsistency of the utility. In this situation it is necessary:
- Download DosBox, Install and Run.
- Mount the disk "with" command "Mount C C: /".
- After that, when you start, press "F2", we recruit 3 times the wrong cipher and do the same actions.
To exclude the likelihood of such situations, it is recommended to get rid of the cipher, turning it off in the PC settings. If you need an acute in it, you should write it in a notebook or any other place so that I don't have to reset again.
In the event that you have lenovo laptop And when starting, the "ENTER HDD PASSWORD" message is displayed on the screen, the method disassembled in this video will help you:

Password reset with HDD or BIOS
Good afternoon, dear blog readers! Today we will talk about neither so frequent, but important. Once faced such a problem as a set password on hDD or BIOS. Probably many do not quite understand, but perhaps I do not understand at all about what I mean. Now I will explain more.
Password on bios.
BIOS is softwarelocated in a constant memorable device (ROM) engaged in self-testing devices and the search for the loader. Naturally, the bios functionality is much wider than described above, but we will not dig deeply, and consider directly on our article. The BIOS password is set to avoid third-party manipulations.
How to remove password with bios
The BIOS password installed does not allow you to get into it and in this case there are three options for solving this situation: reset BIOS settings I reset the CMOS battery on motherboard, rearrange the jumper (jumper) CMOS on the motherboard in the opposite direction (in laptops is not provided) or just closer contacts
and last method Remove the BIOS password using the BIOS Password Removal For Laptops online service. If you know the password and you are simply inconvenient to constantly enter it when you enter the BIOS, you can turn it off by entering the settings.
Password on HDD.
Here the destination and the password function is a little different. If in the first case you just can't get into the BIOS, then when pass installed On HDD you will not be able to download operating system. And this is the lack of ability to use a computer or a laptop for direct purpose.
How to remove password with hdd
If we reviewed three options to solve problems with the bios, then in order to remove the password with HDD, I have only one for you, all the same bourgeois online service. So did not describe above how to use this site. To unlock the password you do not remember, you need to enter it incorrectly three times (for example, 1234 or what you want). After the attempts made in the window, the code will appear, enter it on the site http://bios-pw.org/ and in response to receive the code to reset the password from the hard disk.
How to put a password on hard disk or bios
Set these passwords to protect data and from different manipulations. In each bios, such a function is provided. On the current computers and laptops there is a Security tab where you can install passwords. About this in more detail in pictures.

How to remove a password with a BIOS and HDD on a laptop.
Turn on the laptop and see this ... A wonderful picture is not true? I suppose those who have forgotten the password for the BIOS safely, or someone's smartly smartly joked with a laptop, I will not agree with me. You have not yet been discounted forgotten password BIOS. on a laptop? Believe me, this occupation is not for the faint of heart, where the chances of success strive for zero.
The fact is that, in contrast to ordinary computers, in laptops, passwords are usually stored in non-volatile memory. There are no jumpers for bIOS reset To factory settings, and the removal of the battery rarely leads to a password reset. It remains to rely either for good luck in the selection of the unlock code, or to replace the BIOS and any "shamdes" with eeprom legs (there are such materials on the network). So think again before the laptop pass through the BIOS.
If my warnings did not stop you, admire the picture below, something similar to see, breaking the Notebook to remove the password.
Now scary? Okay, I joked, so dramatically disassemble emachines E510 for another reason. IN this case Everything was easier ...
Password Removing with BIOS Laptop Emachines E510
In general, brought a laptop with a request to see what you can do and lead to the working condition. Previously, he visited the service where he was verdict about the need to replace a pellets hard disk. Apparently there, before the heap, installed and password on the BIOS (so that there was no temptation to turn somewhere else?). I don't care, but the owner of the password on the inclusion of the notebook does not have, but after all, the password on the hard disk is asked after ...
Well, for a start, let's try to remove the password with the BIOS laptop. Climbing over the network, I realized that the latter seld advice The year ended in the year in 2005. Now I do not want to share secrets free of charge. There are, however, specialized forums (In which for a start, it is necessary to register), where different codes are postponed to unlock at the request of the participants, however, sources are kept in the strictest secrecy and they are a ray of mystery (probably to emphasize their chosenness before the rest).
At the end of the article, I will give a reference to one such a mysterious source that helped unlock the Toshiba hard drive without communicating with these "guru". And the English-speaking Google brought me there.
Remove the password with the BIOS on the emachines E510 it was not at all difficult, it was necessary to move the batteries only. Honestly, success was not particularly hoping, but sometimes simple methods It turns out very effective. I do not claim that this method Unlocking is suitable for all laptops, but it is worth trying, the more it does not require any special knowledge and skills.
Laptop Emachines E510 almost the Dream of the Deliveryman (if no serious repair is required), because Provides easy access to the internships. For example, it can be cleaned with only one rear coverThe truth is the latch well, very tight. After removing the cover, we get access to the desired battery:
Attention! Before climbing the contacts, you need to turn off the power and remove the battery from the laptop. Just in case, he held a screwdriver (it was she closed) a couple of minutes, because I didn't know exactly and I don't know how much it is necessary. The main result is a password on the BIOS as it did not happen! However, happiness was not long ...
Password removal with HDD Toshiba MK1246GSX
Here I was waiting for the main ambush. To understand what we are talking about, read the article Password System of Contemporary HDD. The article is not mine, just posted in my blog, so as not to disappear (I am pleased to add a reference to the original source when I find out the author).
The article brought only to familiarize yourself with what we are dealing with, the advice from it did not help. If you carefully read the text, then noted that the Master password from the laptop is not recommended, it converts it. However, I did not accidentally wrote at the beginning of the topic about specialized forums and Guru. It is not necessary to be a genius to understand - unlock codes are clearly not from the head, but I do not believe in supernatural possibilities and chosenness.
We climbed into the brings of the Internet and stumbled upon an entertaining article BIOS Password Backdoors in Laptops on DogBert's blog "s Blog. There was also a link to the online calculator for removing passwords.
The meaning is that after three incorrect attempts to enter a password to access the hard disk, a certain code is issued - Encrypt HDD KEY:
It's time to share, promised at the beginning of the topic, reference: BIOS Password Removal for Laptops. Many thanks to the author of this resource. On my request (entered your Encrypt HDD KEY) two unlock codes were issued, for Acer, HP and Fujitsu-Siemens. The code for Acer fits perfectly, because emachines is almost the same Acer.

How to remove a password from a hard disk?
Removing the password on the hard disk and the laptop BIOS is a fairly common problem with which users often encounter. There are several ways (utilities) that can help remove the password. At the moment, many utilities are popular in solving this problem. To correct this situation, you need to follow certain rules.
Instruction
If you put a password and forgot it, these programs will help you:
Bios_pw.exe (18KB) To remove the password on the computer's BIOS.
HDD_PW.EXE (18KB) To remove the password from the hard disk.
To do this, press "F2" when booting and scored the wrong password three times.
Enter the error code from five digits through a space, which gives a laptop with an incorrectly typed password.
Add via the digit 0.
Now click "Enter". The program will provide you with several passwords. Of these, one must come to the bios.
After you enter passwords on the BIOS or HDD, do not forget to change them to new ones.
In the event that you try to do the above-described actions on a 64-bit platform, difficulties may arise.
The system will give out that it is impossible to start the utility or component, since the program is not compatible with a 64-bit version. The solution is pretty simple.
Download DosBox from the developer's site, install and run.
First, lock the C drive. Make it with the following command: "Mount C C: /".

Password Modern HDD
Immediately make a reservation that the article is not mine and rather ancient (approximately 2005). It is an addition to the previous post how to remove the password with the BIOS and HDD on the laptop. It was not possible to determine the exact primary source, so if you have information about the author, I will gladly post a link.
Any modern drive supports the password system. Before working with a password system of drives, you need to learn two things:
- The drive can be placed either with high ("High") level or maximum ("maximum"). The difference is described below. MHDD reports the level of protection when identifying the drive (F2).
- You can pass the drive by sending the appropriate command by selecting the mode (High or Maximum), and sending a new User password to the drive. In MHDD, you can wage the drive with the PWD command.
Contrary to widespread misconception, it is impossible to "wage" or "block" using a master password. Master password can only be changed. Master Password can unlock the drive in case the user password is forgotten, but it is possible only if the level of protection "High" was set. If the protection level is "Maximum", you can unlock the drive only knowing the user-password.
If the protection level is "maximum", the User password is unknown, but the master password is known, then it is possible to unlock the drive with the destruction of all data using the Security Erase Unit ATA command. This is implemented in the MHDD (FASTERASE command), however, this procedure in MHDD works only with USER passwords.
Thus, the drive blocked with the level of protection "High" can be unlocked using either Master or password user. If the protection level of "Maximum", you can unlock the drive only using the password user or the master password, but with the destruction of all data.
Manufacturers install factory master passwords, and if they do not change them in advance, then they can be used to unlock a salary drive, whose protection level "HIGH".
You can install the User-password by submitting the PWD command to MHDD. This establishes the level of protection "HIGH". The ability to install another level in MHDD is not available for security reasons. Also, the entered password is displayed in the MHDD.log file. After installing the password, the drive must be turned off.
