Hello came to you with a problem. We decided to update the computer, but not all, and the main components: motherboard, rAM, video card and power supply, all this safely installed in our old housing. And now the problem, our BIOS is not in it's a hard disk and drive, both IDE interface devices remained from former computer And we did not change them, the master in the service center connected both drives to our new motherboard with one IDE loop, since the IDE connector on the motherboard is only one. Brought system unit Home and when you turn on the computer, only a black screen, go to the BIOS, there is an inscription: PRIMARY IDE MASTER NO DETECTED and Primary IDE Slave No Detected. Would go back to the service, but we do not live in the city. What can you come up with?
BIOS does not see hard disk
Such a situation comes across to me quite often, probably before your hard drive and the drive were connected to the old motherboard, with the help of individual loops, to two different IDE connectors and both worked in the main position, that is, Master. In the service you simply connected two of your device for one loop, and about the jumpers forgot, now both of your devices work in Master mode, because of this conflict and as a result BIOS does not see hard disk and drive too.
- In our article, we will work with a hard disk and the IDE interface drive, if you have little experience, how to connect and disconnect and what errors you can occur with you, read in more detail if this article does not help you, try one more, in it Described.
Where you gathered a computer, hurried a little and now we will try to fix everything. IDE interface devices need to be configured with a jumper, it will prompt your computer how to properly access the drives (and disk drive). Computer when working with iDE devicesIt is very important to know who is on one plume by the main device Mas Ter, and who subordinate to Slave is solved small. Contacts on which the jumper is satisfied, are directly on the drive. Instructions for the arrangement of the jumper, is usually on the storage case. Turn on the computer and go in, first of all you need to make sure if the IDE controller is enabled in the Integrated Peripherals tab.
We are convinced that power cables are connected.
In my article, we will adjust the jumpers first of the Seagate hard drive, then to acquire the Western Digital and Maxtor Winchester experience, Sony Nec Optiarc will appear as a drive. Pay attention to the exhibition. I also have a similar problem, BIOS is not in it's a hard disk Both drives, both devices are not defined by Primary IDE Master No Detected and Primary IDE Slave No Detected.
From the very beginning, we look at the jumper on the Sony Nec Optiarc drive. According to the instructions located on the storage case, the extremely right Master position, which means the drive is already connected with the jumper as the main one. Best to connect the main Master device by the end of the loop.
Now go to K. hard disk, SEAGATE Winchester is also connected as Master, two main devices on one plume is an inevitable conflict.
The result of both devices in the BIOS position no detected. Let's avoid conflict of devices and leave our drive as a master, and the seagate rigid disk connect as a slave slave. We look at the instructions and see that the seagate hard drive works in the subordinate mode at all without jumper, we remove the jumper at all.
We see if everything is connected correctly and turn on the computer. The result is obvious, both devices were found and decided. Now we also connect Western Digital Winchester, everything is perfectly determined in BIOS. Behind him is a hard drive MAXTOR, too, everything is fine.
Many may notice, and if a hard disk connect to the end of the loop and make the main-master, and the drive in the middle and subordinate-slave, because it is always more important device Connect to the connector at the end of the loop, you want to do so, after all, the work of the hard drive is more priority to us. Then the main thing is not to recycle very much the train itself, not wisely, it will look like that of you, approximately as in the symbol.
TORMEMIT hDD) How do you not connect them. And what in our case? We look at the BIOS, the speed of our Sony NEC Optiarc -UDMA-4 DVD Roma-4 is most likely a seagate UDMA-5 Winchester will work in UDMA-4.
What am I so? But what if you have a completely old drive, it is better not to connect it with one loop at all, since the speed of both devices will be quite low, most likely to PIO, so draw in this case to a new one.
When turned on computer BIOS. Checks the hardware on the workbar b. Accordingly, if the hard drive is not visible in the BIOS, the system will not start, because windows files Will not be detected and read. Visually, this error is accompanied by the appearance of a black screen with a notification that the Winchester is not found.
Possible reasons
If the BIOS does not see the hard disk, then the reason for this phenomenon can be both hardware and software errors In the computer. Consider the main negative factors:
- Winchester is disabled in the bios.
- The hard disk is incorrectly connected or damaged.
- Improperly set jumpers
The described reasons are more relate to the HDD, but if you have an SSD kit, then some advice is equally applicable to it.
Incorrect connection of Winchester
If the BIOS does not see the hard disk, then the problem can be wounded in the improper connection of the hard drive to the motherboard. Check that all loops are good, the cables do not have chances and cuts, suitable ports are used to connect. If a lack of a physical property is found (for example, a torn cable), it should be eliminated, after which try to upload the system again.
The recommended SATA cable length is 1 meter. If your cable exceeds this value, then it must be replaced by a shorter, as this is the cause incorrect work BIOS. Be sure to check that all cables are securely connected - sometimes they just fall out of the connectors.
Problem with jumpers
If you are connected simultaneously two hard drives, and you use the IDE interface, then you need to check the installation of the jumpers on the hard drive. The jumpers reported which HDD presenter (i.e. master), and what is the slave (Slave).
Note: If you are connected to two SSD drive, no jumpers are required.
Instruction in proper installation The jumpers can be found directly on the hard drive housing. If the disk is two, then one must be set as "Master", and the second is like "Slave". Be careful: some hard drive models work in the subordinate mode without jumper.
Pay attention to the other equipment - if it is connected incorrectly, the BIOS will work with failures, which results in an error when trying to detect the hard drive. The cause of the problem can be the usual overheating: check the cooler and bring the entire cooling system in order.
Checking BIOS.
Any equipment connected to the computer is turned on and off through the BIOS. Sometimes software failure It leads to the fact that changing the mode of operation of the device occurs without the knowledge and user participation.
- To start .
- Make sure that the "SATA" connector has the value "AUTO", that is, it is determined automatically.
- Find the "SATA Configuration" parameter and set it the value "Enabled".
If you are afraid to climb the BIOS settings, try simply reset them to the factory state. Pull out out motherboard A small battery or use the "Load Optimal Defaults" item in the "EXIT" section.
Winchester damaged
If any manipulations with the plumes, itselves hard disk And the bios do not bring a positive solution to the problem, then you should think about the state of the hard drive. First of all, try to connect it to another computer. If the BIOS does not see the hard drive here, then the carrier is most likely broken. In this case, it is better to think about how to save information, as the damaged hard drives are usually not subject to recovery.
Good day, dear readers! In this article I will try to explain why the BIOS does not see the hard drive - as well as the ways to solve such a problem, I will tell in my article.
Such a problem when the hard disk is not determined by the computer, is the most common. It occurs, both on old and new computers. It also happens with new and old, external and built-in HDDs.
To begin with, of course, it is required to know the cause of such a problem. Sometimes users can independently decide and establish work with Windows and a hard disk of the laptop.
Why doesn't the computer sees a hard drive?
I note immediately that there are several reasons, because of which the Winchester refuses to perform its functions. To such reasons include:
- For the first time, the new SATA or IDE disk occurred;
- There were problems with a loop or wires;
- Perhaps the BIOS is incorrectly configured or completely out of action;
- Weak power supply;
- Low cooling system;
- Winchester itself failed.
Yes, you need to diagnose, and then solve the problem. Let's say, at an inexperienced user, some difficulty will arise with it. Let's help you, and we will deal together what and how.
The first connection of Winchester
If you first connect the screw, then, most likely, the system simply did not see him. Yes, it is physically in working condition, but it is not displayed among the local disks.
In order to correct this problem, you need to click on the Win and R keyboard, write a compmgmt.msc and specify "OK".
Lay and select "Drive Management".
In the appeared window, all your connected discs will be revealed in the middle, including your problem hard disk. As a rule, it is due to the wrong designated letter.
Layout the desired disk and click on it with the right mouse button, and then select "Change the drive letter or the path to the disk ...". "
A window will open in which you will need to click on the "Edit" button.
Now select the desired letter and specify "OK".
Wrong format
For the normal operation of the disk in Windows, the NTFS format is required.
Just as in the instructions above, go to "Disk Management", that is, repeat the previous first two steps. After that right-click on the disk and select "Format".
Choose file System - NTFS, and click "OK".
BIOS does not see the hard disk - setting
IN some cases In BIOS, the wrong priority of devices for download can be installed. When booting a PC, press F2 (or DEL). On which key you must click on the start of the PC. By clicking on the desired key, you will go to BIOS.
Please note that because of the differences in the versions of the BIOS names of the menu items here and can then be slightly different.
Lay the tab "BOOT". Use arrows to control. In the list of download devices on the first place (1st boot priority / first boot device), set your HDD.
Press F10 to save and output and then press Y to confirm. After that, the PC will be downloaded from the device you exhibited.
SATA mode
Often, users in BIOS missing operation mode, joint with IDE. In order to change, you need to go to BIOS, select Main, Advanced or Intefrated Peripherals and find the SATA OPERATION setting, Configure SATA AS, or onchip Sata Type.
Select IDE or Native IDE, press F10 and specify Y.
BIOS does not display hard drive
If the BIOS cannot determine your hard drive, then, most likely, the case is in incorrect adjustment or their fails.
Invalid settings appear due to user actions, and failure can occur for various reasons. So, ranging from nutritional interruptions and ending with even infection of the system. This may indicate a system date - if it is not accurate, then you have undoubtedly failed. To resolve this problem, you need to reset all settings.
Lay on the motherboard Jumper Clear CMOS.
Change the jumper from the contacts 1-2 by 2-3, hold them of the 20-30 seconds and then return to initial position. In addition, there is another way. In the system unit, find the motherboard and pull out the battery from it.
You will need to return it back in 25-30 minutes.
Conclusion
Now you know what to do if the BIOS does not see the hard disk. I hope you could solve your problem, thank you all for your attention, as well as forget to ask any questions in the comments!
The computer is a combination of elements that must work simply. For example, a hard disk is the most important component of the computer responsible for storing information. Today we will look at the problem at which the BIOS does not see the hard disk.
BIOS - special utilitywhich sets up a motherboard. When you start a computer, the BIOS is entering, checking the performance of the equipment and preparing a computer to launch operating system. BIOS may not see the hard drive for various reasons, starting with system errors and ending with the malfunction of the hard disk.
Why does BIOS sees a hard drive?
Cause 1: Incorrect connection
As a rule, a similar problem occurs or when the computer is first run, or after opening the computer.
IN this case It is recommended that you make sure that all the loops are connected correctly, there are no bends and damage, and this concerns not only the hard disk, but also other computer equipment, such as cooling systems.
And only after you transfer the correctness of the connection of all components of the computer, you can proceed to the following reason.
Reason 2: problems with jumpers
Jumpers are special hard disk jacks to which other equipment is connected (through loops).
Any noticeable eye violations on jumpers may be the main reason The inoperability of the hard disk, because the problem jumper cannot give the BIOS normally to send the signal to the equipment.
If the violations in the jumpers were discovered on a new hard disk, then be sure to contact the goods acquisition and return or exchange the equipment. If the defect was discovered already on the hard disk appealed, you should contact service centerwhere the problem can be easily eliminated.
Reason 3: Files in BIOS
Quite often, failures can occur in the BIOS, for example, due to the action of viruses on the computer. In this case, to check this cause of the problem, you will need to log in to the BIOS to check the settings.
Depending on the bIOS version Further menu items may differ. You will need to find a section. "INTEGRATED PERIPHERALS" and then go to "Advanced" . Here you can find a tab "Onboard Devices Configuracion" which will be located ONBOARD IDE CONTROLLER or "Marvell IDE Controller" (The name of the item may differ depending on the motherboard). If about this item is worth the status "Disabled" , this is the reason that the BIOS does not see the hard disk, because A function that allows the BIOS to see the hard disk simply disabled. All that will be required of you - change the status on "Enabled" , Save settings and exit BIOS.
If you could not find the right menu item, but still confident that the reason that the BIOS does not see the hard disk, are the wrong settings, then you can try to reset the settings before the initial state.
Cause 4: Hard disk malfunction
If checking the correctness of the connection, the integrity of the jumpers and bIOS settings They did not give any result, it is worth suspection of a hard disk malfunction.
To check such a likelihood of a problem, you should try to connect a hard disk to another computer. If another computer could not see the connected equipment, then the reason is clearly lies in the malfunction of the hard drive.
In this case, as an option, you can try to disable a hard disk from the computer for a while, execute bIOS reset before initial settings, Connect a hard disk and try formatting, for example, using Windows installer.
If after formatting hard disk you could not achieve positive result, Most likely, the hard drive is faulty. In this case, you have two options: contact the service center or purchase a new one.
At present this device The most necessary and relevant to store memory. However, many often faced such a problem as "BIOS laptop does not see a hard disk." BIOS is responsible for controlling the motherboard and devices connected to it.
Hard disk is a systemwhich stores information in itself, and is responsible for the performance of the software.
The main reasons for the lack of connection
The first thing you need to do is check the connection of ATA or SATA ports, as well as their automatic setting.
If everything is fine with the ports, and they are good, then to identify why it is not displayed, it is possible in the following actions:
- Check the connection of all components.
In order to determine the true cause, you need to make sure that all the elements are correctly connected. It is necessary to view the finding of the loop, the motherboard, as well as their health and disadvantage.
If all the order with these devices, it is necessary to pay attention to other elements, they may have caused a failure in the BIOS.
- Check the service of jumpers.
Jumpers are socketsTo which all the plumes and wires are connected.
If the problem is in jumpers, then it can be fixed in the following ways:
- very gently handle the surface, removing rust;
- clean the jumpers with sandpaper, but it is necessary to be very attentive and neat.
If the actions did not help, then you should contact a specialist who will eliminate this problem.
- The following action is when you start a computer, you must go to bIOS systemWhat can be done by pressing the F 2. Combination in the Integrated Peripherals menu, which will open, are the parameters and hardware data.
Most often in bios external storage Displayed like Drive or Primary Master, in order to see, it is turned on or not, in most cases installed auto modeHowever, it is possible that the OFF parameter is assigned to it. In this case, it needs to be included.
If after switching on nothing changed, and the BIOS still does not see the hard drive, then you need to remove the batteries from system board, Wait half an hour, and again put everything in place, after that restart the computer.
Often it helps to solve the problem.
- No motherboard drivers. That is, when windows installationThe drivers were damaged, or they were not at all.
In order to install the drivers, you need to insert the drive, the second action is to turn off the computer, connect the device with the SATA interface and turn on the computer.
- Connection adapter (cable) does not work.
It is required to check the motherboard connectors for the presence, cracks, fractures, and other damage. If there are any violations, the cable must be replaced.
- The drive does not rotate.
To find out, he rotates or not, It is necessary to turn off the computer, open the system unit, turn on the computer and listen to the sound if there is vibration, then everything is in order, if not, then the problem is in the accumulator.
The reasons why the drive will not rotate, this is the lack of nutrition or its insufficient amount.
- The hard drive is faulty. In this case, it is necessary to return or exchange it in the store if possible.
Winchester Connection Instructions
1. Turn on your device, next instantly you need to press "DEL", the BIOS menu will unfold. Next, go to the "Main" window and click "Enter". Options will open where the hard drives will be listed. You need to find the necessary hard drive if it is not, you should select the "SATA" connector and press the auto mode.
After these actions, the hard disk will be available in the computer.
2. If the first action did not help, but most likely the controller is turned off sATA interface. Select the "SATA Configuration" string and in the Controller tab, click "Enable".
3. After the actions have done, you must restart the system, and update the equipment configuration. After that, the BIOS should determine having hard disk.
After checking the connection of all elements and devices of the hard drive, motherboard and other components, you can solve this problem that the hard disk is not defined in the BIOS.
However, it should be considered that it is best to choose a hard drive in a specialized store, with a certain period of warranty.
Do not purchase HDD discs on the market, or in doubtful organizations. It is also necessary to take into account the characteristics, features and properties of the hard drive.
Most problems can be solved by the proposed methods at home and independently, but it does not always help it and to prevent its full breakdown, better contact a specialist.
