Find out what chip is on the flash drive. Determination of the memory chip, VID and PID of the flash drive

Utilities for low-level work with flash drives allow you to restore the actual volume of the drive, eliminate errors in operation, improve the operation of the controller, etc. But the main feature of such programs is that they are very narrowly focused. And only with their help is it possible or memory cards. Each chip and even controller has its own specialized program. And until you find it, there can be no talk of any recovery or resuscitation of the flash drive.

How to determine the memory chip, VID and PID on a flash drive without opening the drive?

All the programs below are completely free and show the most accurate data.

For this, there are special programs for diagnosing flash drives and memory cards. It is with their help that you can find out all the necessary information. First of all, these are such programs as Chip Genius, CheckUDisk, UsbDeview and others.

one . Determination of the memory chip, VID and PID using ChipGenius. This is one of the most convenient and powerful utilities in its class. main feature programs - automatic update when recognizing the memory chip. The utility connects to the server and updates the database, so it shows the best results.

2. These parameters can also be found using CheckUDisk. A pretty good functional program that allows you to find out all the information about flash drives in a matter of seconds. However, in some cases, the memory chip cannot be recognized, especially when it comes to Chinese memory chips from little-known manufacturers.

3 . USBdeview is another USB flash drive diagnostic tool. Allows you to quickly and effortlessly find out all the necessary information to search for low-level flash drive formatting utilities.

These are the most comfortable and functional programs to work with USB flash drives that must be used for recovery. Of course, this is not a complete list. possible ways resuscitation of memory cards. Depending on the situation and the availability of free time, you need to try others.

Probably, many of you, friends, have come across a situation where you urgently need to write something to a USB flash drive, but the recording goes on and on and never ends. How to understand whether our flash drive is really writing data slowly or does it just seem to us so? Maybe this is the norm for this type of device? We can measure the speed of reading and writing media data special programs. But what will it give without understanding how it should be normal? Maybe other people are even worse off? There are no official standards fixing the standards for real (namely, real, not potential) speeds of flash drives on each of the generations of the USB interface. Only practice can give such information, but where can one find its generalization? In this article, friends, we will measure the speeds of flash drives with other people and try to answer all the questions posed.

A long write of data to a flash drive is by no means a subjective phenomenon, exacerbated in moments of haste or when we are annoyed. This is a real fact, for the fight against which today we have grandiose prospects, but, alas, their poor implementation. USB 3.1 interface specification Gen 2 with maximum throughput 1250 Mb / s was adopted back in 2013. However, not all new computers are equipped with this interface today. Novelties on the flash drive market, if they provide for compatibility with USB 3.1, actually work at the level of real USB 3.0 performance. Those models that can actually offer modern speeds are usually sold in large volumes (starting from 64 GB) and are more expensive. USB flash drives 3.0 of the same capacity.

Conditional standards

There are conditional (of course, unspoken) standards for the speed of flash drives, which determine the minimum that the device should produce:

On the USB 3.0 interface: reading - 65 Mb / s, writing - 15 Mb / s;

On the USB 2.0 interface: reading - 20 Mb / s, writing - 5 Mb / s.

When specifying the speed, we mean the maximum developed during sequential reading and writing data. The higher the indicators from the indicated minimum, the better, respectively. And if the flash drive lags behind these standards, it is either bottom or faulty. And, perhaps, you should think about purchasing a new, better device, with good type flash memory.

Such conditional standards give a primitive understanding of whether our flash drive is bad or good. But how bad or good it is compared to other models, specialized benchmark services will be able to answer in detail. Such as, for example, Usbflashspeed.Com.

About usbflashspeed.com

Usbflashspeed.Com is an English-language benchmark project created to test and compare the performance of flash drives from users around the world. The database of the project is created by us, ordinary people. The service offers to download special utility, which measures the performance of flash devices and publishes them on the service website.

On the home page Usbflashspeed.Com presents test results various models flash drives, SD cards and SSD drives:

In the top ten in terms of data reading speed;

In the top ten in terms of data recording speed;

In the last ten tested devices.

Well, friends, I propose to start by looking at the performance of top-end media, and then proceed to testing and analyzing our flash drive.

Best Devices

Because Usbflashspeed.Com published test results different types flash drives, respectively, with different connection interfaces, in order to see the standards of USB flash drives, we filter the site data by media, for example, with a volume of 8 GB. Of course, this is a very rough method of screening, but, alas, the service does not provide filters for the types of flash devices.

And now we are looking at the TOP 10 best drives in terms of data reading speed. From the fourth position, these are supposedly ordinary USB 3.0 flash drives, and their data reading speed ranges from 74-100 Mb / s. A somewhat strange TOP-10, it is obvious that there are USB 3.0 flash drives that read faster than 100 Mb / s. But oh well, that's not the point.

And now let's see the TOP 10 devices in terms of data recording speed. Not the coolest, but one of the best flash drives, according to the benchmark service, can write data at a speed of 26-81 Mb / s.

Top Ten Devices Tested

The third ten of the service - "Last 10 benchmarked Flash Drives" - is a list of the latest tested devices. And this list reflects objective reality better than others: in it we will see those high-speed capacities that are checked by users who, for the most part, are not owners of super-flash drives. In the list filtered by the criterion of 8 GB, of course, SD cards can be confused, but basically the list will consist of USB flash drives. So, at the time of taking the screenshot below, the last ten of them had speed:

Readings - 13-83 Mb / s;

Recordings - 5-19 Mb/s.

Although the boundary indicators are not bad, it still turned out to be a sluggish list. Let's, friends, diversify it with more remarkable figures. If the trend continues, with our flash drive Kingston DataTraveler 3.0 in the last ten devices tested, we will lead until we are chronologically removed from view. Well, let's go.

Flash drive speed test and its comparison with others

Download the portable FlashBench utility from Usbflashspeed.Com.

Unpack, run, specify the media disk in the utility window and start testing.

Note: The FlashBench utility not only tests the speed of reading and writing data from a flash drive, it also displays its characteristics like this: serial number, volume, VID and PID. The last two characteristics may come in handy when looking for software for flashing the controller.

As a result of testing in the utility window, we will receive a link leading to the benchmark service website. Copy it and paste it into the browser window.

To begin with, my friends, I launched testing a flash drive on a USB 2.0 interface in order to evaluate its speed capabilities within the limits of computer devices. Quite average results were: reading - 31 Mb / s, writing - 13 Mb / s.

The Usbflashspeed.Com service removes our results from the dozens of the last tested devices over time, but stores everything in its database, combining data for each model. Thanks to this, we can compare our flash drives with the same models that are used by other users and differ in other test conditions (another USB interface on a computer, another file system). Well, and, perhaps, differing in other modifications of the model itself. When you click on the link of the device name, we get a chronologically built list of tests for this model.

You can view such information on your drive without participating in testing. To do this, you need to find it by name using the site search engine.

Eventually

Extremely, friends, the site Usbflashspeed.Com is useful. First of all, of course, those who want to buy a good, fast carrier and are faced with a choice. A leisurely review of the contents of this benchmark service, perhaps, will be added to the tips outlined in the article “How to choose a USB flash drive”.

USB flash drives are reliable devices, but there is always a risk of breakage. The reason for this may be incorrect work, firmware failure, format failure, and so on. In any case, if this is not physical damage, you can try to repair it with software tools.

The problem is that not every tool is suitable for repairing a particular flash drive, and using the wrong utility can permanently disable it. But knowing the VID and PID of the drive, you can determine the type of its controller and select the appropriate program.

VID is used to identify the manufacturer, PID is the identifier of the device itself. Accordingly, each controller on the removable drive is labeled with these values. True, some unscrupulous manufacturers may neglect paid registration ID-numbers and assign them just at random. But mostly it concerns cheap Chinese products.

First, make sure that the flash drive is somehow detected by the computer: a characteristic sound is heard when connected, it is visible in the list of connected devices, displayed in "Task Manager"(perhaps as an unknown device) and so on. Otherwise, there is little chance not only to determine the VID and PID, but also to restore the media.

ID-numbers can be quickly determined using specialized programs. Alternatively, you can use "Device Manager" or just disassemble the USB flash drive and find information on its “insides”.

Please note that MMC, SD, MicroSD cards do not have VID and PID values. Applying one of the methods to them, you will get only the IDs of the card reader.

Method 1: ChipGenius

Perfectly reads the main technical information not only from flash drives, but also from many other devices. Interesting that ChipGenius has own base VID and PID to give guessed device information when the controller fails to poll for some reason.

To use this program, do the following:

Run her. Select the flash drive at the top of the window.
Bottom opposite value « USB device ID" You will see VID and PID.

Please note: older versions of the program may not work correctly - download the latest ones (you can find just such one at the link above). Also, in some cases, she refuses to work with USB ports 3.0.

Method 2: Flash Drive Information Extractor

This program gives more detailed information about the drive, of course, including VID and PID.

After you have downloaded the program, do the following:

Method 3: USBDeview

The main function of this program is to display a list of all devices ever connected to this PC. Additionally, you can get detailed information about them.

Instructions for use are as follows:

Method 4: ChipEasy

An intuitive utility that allows you to get comprehensive information about the flash drive.

After downloading, do the following:

Run the program.
Select the desired drive in the top field.
Below you will see all its technical data. VID and PID are in the second line. You can select and copy them "CTRL+C").

Method 5: CheckUDisk

A simple utility that displays basic information about the drive.

Further instruction:

Run the program.
At the top, select the flash drive.
Check out the data below. VID and PID are located on the second line.

Method 6: Studying the Board

When none of the methods helps, then you can take drastic measures and open the case of the flash drive, if possible. VID and PID You may not find it there, but the marking on the controller has the same value. Controller - essential part USB flash drive is black and square in shape.

What to do with these values?

Now you can start using the information received and find an effective utility for working with your flash drive. To do this, use where users themselves form a database of such programs.

If you have been using a flash drive for many years, and there were no problems, but one day when you connected it to a computer, it was defined as an unknown USB device, or it was not detected at all, then you need to deal with the problem. Remember if you dropped it. If there was such a case, then the damage is physical, and these tips will not help.

If you did not use safe removal when disconnecting the flash drive from the computer, or it was no longer detected after formatting, then you can use VID and PID to select some program that will help restore the USB drive to working order.

What is VID and PID, and how to find out these parameters, will be discussed in this article. VID - identifies the manufacturer, and PID - the device itself. From flash drives that are produced by large companies, certain values \u200b\u200bof each parameter are taken and assigned to all USB drives. For example, everyone flash drives Transcend The VID is 8564 and the PID is 1000. Some manufacturers leave the VID and PID for the USB drive the same as the controller installed in it. Well, if you have a cheap Chinese flash drive, then VID and PID are just random, meaningless numbers.

If you format the drive with some unsuitable program, then it may stop working altogether. Let's look at the ways in which we can find out the values we need. Then you just need to use the online service, which contains a database of suitable programs for restoring a flash drive of a certain model.

Using Device Manager

The easiest way to find out the VID and PID is to look at these values by opening the Device Manager.

In Windows 7, click on the "Start" button and select from the list on the right. If you do not have such an item, type "control panel" in the search bar and click on the appropriate result.

If you have Windows 10 installed, then right-click on the "Start" button and select from the menu.

Then double click on the item "USB Controllers". In the dropdown list, select "USB mass storage device" and click on it with the right mouse button. If your flash drive is not defined, then you will have an item like "Indefinite USB device» . Further from context menu select .

In the next window, go to the "Details" tab. In the upper field "Property" from the drop-down list, select "Hardware ID". A little lower in the "Value" field, VID and PID will be indicated.

Using Utilities

There are many programs that will help you find out the VID and PID values \u200b\u200bof a USB drive. In addition, they will show other information about your device. Let's look at a few popular programs.

Flash Drive Information Extractor

Flash Drive Information Extractor shows all necessary information about USB storage. Insert the flash drive into a free USB port and wait a minute. Then run the program and click on the button in the window that opens. "Show flash drive information".

The program will give the result very quickly. Find the VID and PID fields and see what values your flash drive has.

ChipEasy

ChipEasy will show a little less information than the previous program, but you can see the parameters we need. Run the program and double-click on the required USB drive in the upper field.

In the detailed information area, the VID and PID will be shown in the "Device ID" field.

ChipGenius

With the ChipGenius program, everything is also very simple. Launch it and click on the connected flash drive in the upper area to view detailed information about it. Then, a little lower in the "USB Device ID" field, look at the parameters of interest.

USBDeview

The USBDeview program must be selected depending on the bit depth of your operating system. If you have 32-bit Windows installed, then select the appropriate USBDeview file and run it, if 64-bit, then run the file with the number 64 in the name.

The main window of the program displays all the devices that have ever connected to your computer or laptop. It can be difficult to find your flash drive in this list, so click on the “Settings” button and uncheck the box.

Now the main window displays only those devices that are connected to the computer on this moment. Find your device in the list and click on it.

The properties window will open. In it, we will be interested in two parameters: “Product Code” is the PID, and “Supplier Code” is the VID. The same parameters can be viewed in the lower right field "Device instance code".

How to look at the USB drive itself

If you can’t find out the VID and PID data using various programs, then you can disassemble the USB flash drive. Do this carefully so as not to damage anything, otherwise the device will definitely become inoperative.

On the board of each flash drive there is a black rectangle or square - this is the controller. You can see the label on it. For example, a Kingston flash drive has a PS2251-37KS controller installed. Knowing the marking of the controller, you can also choose the right recovery method for the flash drive.

After you know the VID and PID values, you can use the iFlash online service. Here is a database that is created by the users themselves, which program, which flash drive is best to reanimate.

On the main page of the service, enter your data in the fields "VID" and "PID" and click the "Search" button.

A table will appear on the page. The first column will write who the manufacturer is, the second column will be data about the model. The Chip Model column provides information about the controller.

Find your flash drive according to these parameters, and if you're lucky, the last column will contain the name of the utility that you can use to restore your flash drive.

Bring your flash drive back to life with the right program. You can pick it up by finding out the VID and PID of the USB drive. And how to do it, you already know.

Greetings to all blog readers!

Probably the majority of those who more or less often work with a computer have a flash drive (or even more than one). Sometimes it happens that the flash drive stops working normally, for example, when formatting is unsuccessful or as a result of any errors.

Quite often, the file system can be recognized in such cases as RAW, the flash drive cannot be formatted, go to it too ... What to do in this case? Check out this little guide!

This instruction for restoring the performance of a flash drive is designed for a variety of problems with USB media, Besides mechanical damage(the manufacturer of a flash drive can, in principle, be anything: kingston, silicon-power, transced, Data traveler, A-Data, etc.).

And so ... let's get started. All actions will be listed in steps.

1. Determining the parameters of the flash drive (manufacturer, controller brand, amount of memory).

It would seem that it is difficult to determine the parameters of a flash drive, especially since the manufacturer and the amount of memory are almost always indicated on the body of the flash drive. The point here is that USB drives of even one model range and one manufacturer can be with different controllers. A simple conclusion follows from this - in order to restore the performance of a flash drive, you must first accurately determine the brand of the controller in order to choose the right utility for treatment.

A typical type of flash drive (from the inside) is a board with a microcircuit.

To determine the brand of the controller, there are special alphanumeric values specified by the VID and PID parameters.

VID - vendor ID
PID - Product ID

For different controllers, they will be different!

If you don't want to kill the flash drive, then by no means use utilities that are not designed for your VID / PID. Very often, due to an incorrectly selected utility, the flash drive becomes unusable.

How to determine VID and PID?

The easiest option is to run a small free utility CheckUDisk and select your flash drive in the list of devices. Next, you will see all the necessary parameters for flash drive recovery. See screenshot below.

VID / PID can be found out without using the utility.

To do this, you need to go to Device Manager. In Windows 7/8, it is convenient to do this through the search in the control panel (see screenshot below).

In the device manager, the flash drive is usually marked as "USB mass storage device", you need to right-click on this device and go to its properties (as in the picture below).

On the Details tab, select the Hardware ID option - VID / PID will appear in front of you. In my case (in the screenshot below), these parameters are equal:

2. Search for the necessary utility for treatment (low-level formatting)

Knowing the VID and PID, we need to find a special utility suitable for restoring our flash drive. It is very convenient to do this, for example, on the site: flashboot.ru/iflash/

If suddenly nothing is found on the site for your model, it is best to use a search engine: Google or Yandex (request, type: silicon power VID 13FE PID 3600).
