What to do, often the digital flash drive (most often the controller in it) breaks down, generates errors, the flash drive does not open on the PC - not even a month will pass. One day the flash drive may need to be restored. The reason that maybe:

incorrect, careless operation of the flash drive
incorrect formatting of the storage medium
a low-quality flash drive bought on the market or cheaply from a Chinese (probably by mistake)
physical or software failure of the flash drive (the most likely reason)
also, an incorrectly removed USB flash drive from a computer or laptop can serve as a reason for inoperability. This happens when an impatient user literally rips the flash drive out of the USB socket while copying or transferring files.

I finish with the lyrics and go directly to the topic of the post ..

If your flash drive stopped be defined like a disk does not want formatted, does not allow the information to be recorded or something else happened to it, BUT it has no mechanical damage, then you should know that all is not lost. Most likely bug controller and you have to tinker with it a little. This procedure takes about 5 minutes.

I must say right away that there is no universal programs for recovery of all varieties flash drives... You will need to find exactly the one that can work with the controller of your flash drives.

First, we need to define VID and PID non-working flash drives.

Determine VID and PID for flash drive recovery

Stick uSB flash drive into your computer and run device Manager. Start – Execute - mmc devmgmt.msc.

Then go to the section USB Universal Serial Bus Controllers.

Find your own in the list uSB flash drive... Usually, everyone flash drives have a name USB storage device.

Press the right key on the device and open Properties.

Go to the tab Intelligence.

In the drop-down list, select the item Instance code devices or Equipment IDs.

In this window we see PID and VID.

Search for a program to recover a flash drive

We go to the website FlashBoot.ru and enter the received VID and PID.

Click on the button Search.

In the results, we look for our manufacturer and model of the flash drive. I have this Kingston DataTraveler 2.0.

The right column will contain the name of the program we need or a link to it.

All. Now search Google for the program by name or download from the specified link. Launch and follow the instructions. Usually, in such programs for recovery there is only one button, so you shouldn't have any questions.

That's all!

If you have any questions - ask in the comments.

Cure for the Flash Drive! (software repair of BAD blocks)

Good day!
The reason for writing this article is my two Kingston sticks.
One of them was not used for quite a long time, and when I decided to use it, it turned out that it was not possible to write data to it! Using the HD Tune 3.5 utility, it was found out that a decent part of the surface is marked as unreadable! Attempts to format using Windows did not lead to anything, due to the fact that when formatting a USB flash drive, only service information is created. Low-level formatting was required, a utility for this was found without problems using Google. The format was produced and it worked.
A few days ago, when trying to copy sources from a second flash drive, a message was issued that it was impossible to copy such files. Moreover, you could delete these files! The first thought is that BAD blocks have appeared.
Checking the flash drive with HD Tune 3.5 did not reveal any BAD s!

The reason for the unreadability of the files remained undetected for several days, until I came across the HDD Scan 3.2 utility.

The surface test carried out with its help immediately revealed the presence of BADs, which actually explained the unreadability of the files! In addition, the reason for the failures in the speed of writing and reading files immediately became clear, these are sectors with an access time of more than 150 ms.

To eliminate them, the previously found utility for low-level formatting HDD Low Level Format Tool was used.

After the end of formatting, a surface test was carried out using the same HDD Scan 3.2.

BAD blocks were eliminated, we also managed to get rid of slow sectors, which eliminated gaps in write and read speed.

Output.
Using HD Tune for surface testing is not recommended, it gives incorrect results, so it is better to use other utilities such as HDD Scan or similar.
To disinfect BAD blocks, you must use low-level formatting utilities. In addition to eliminating bad sectors, it eliminates clusters with long access times, which ultimately eliminates read and write speed gaps.
Using a similar method, you can return to work as if it were not working flash drives, but it is worth remembering that it is no longer worth trusting such media, the wear process that has begun can no longer be stopped and over time the number of bad sectors will grow and eventually the time will come when the media can no longer be used ! The time of complete failure depends on the intensity of using the flash drive!
This technique and a set of software can be used not only for flash drives but also for hard drives, both portable connected via USB and stationary with an IDE and SATA interface.

Best regards - StrateG-1.

We express our opinion

Broken sectors are an integral part of our digital life. Many of us are already accustomed to this kind of crash from time to time, but a new user who sees an error message while connecting a removable disk to a computer can lead to panic. Removable drives store a small amount of data in each of their sectors and sometimes it happens that one of them gets damaged. Such sectors are called broken.

In this article, we are going to walk you through the steps required to fix bad sectors on a flash drive or any larger storage medium connected to your computer. This method will require using a device with Windows operating system installed on it.

Logical - storage space that is not working properly. The operating system, while trying to read the sector data, receives an correction error code that does not match the content. Then the system marks it as broken and stops using it for storing information. Such drives can be recovered by overwriting the disk (low-level formatting).
Physical - physically damaged media space. Such damage cannot be repaired.

So how do you fix bad sectors in a removable storage device? Fortunately, there are several ways you can help you deal with this crisis.

Eliminating bad sectors using Windows Explorer

The first and most important troubleshooting method is Windows explorer... An easy-to-use interface will allow you to check the media connected to your computer for bad sectors and eliminate them.

Note: We used Windows 10 to run the disk analysis utility. The Windows 8.1 user interface is similar, however it may differ from Windows 7.

Troubleshooting steps:

Recovering bad sectors using CMD in Windows

If the UI-based utility does not resolve the issue, try using the Windows Command Prompt. Check Disk is used to perform an operation to check the connected media for errors. To open CMD in administrator mode, right-click on the Start button and select Command Prompt (administrator).

Use the following command to test your drive:

chkdsk C:

Here C is the path / drive letter assigned to your media. You will need to write the symbol corresponding to your drive (in our case, this is E). Open My Computer to see the correct drive letter.

To correct errors on the media, enter the following:

chkdsk / f E:

The command will help you find and eliminate the broken sectors:

chkdsk / f / R E:

The Check Disk utility will recover any “logical” bad sector present on the removable drive. Restart your computer when the recovery process is complete.

The above methods will work for SD cards, MicroSD cards (connected with an adapter) and for external / internal hard drives.

If you need to restore and save information in advance, the Starus Recovery tools will help you. You can download and try programs for recovering deleted data on removable storage absolutely free! The functionality of each program has a preview window. This function will help you make sure that a specific file is not damaged or overwritten, which means it will be successfully restored.

Perhaps every user sooner or later faces the problem of the performance of the flash drive. If your removable storage device stops working normally, do not rush to throw it away. In case of some failures, performance can be restored. Let's consider all available ways to solve the problem.

It should be said right away that all procedures are performed quite simply. Moreover, the problem can be solved without even resorting to some unusual means, but just use the capabilities of the Windows operating system. So let's get started!

Method 1: Check Flash Program

This software effectively checks the performance of a flash device.

Install the program. To do this, download it from the link above.
In the main window of the program, follow a few simple steps:
- in chapter "Access type" select item "Like a physical device ...";
- to display your device, in the box "Device" click the button "Refresh";
- in chapter "Actions" check the box "Reading stability";
- in chapter "Duration" indicate "Infinitely";
- press the button "Start".

The check will begin, the progress of which will be displayed on the right side of the window. When testing sectors, each of them will be highlighted with the color specified in the Legend. If everything is in order, then the cell glows blue. If there are errors, the block will be marked in yellow or red. In the tab "Legend" there is a detailed description.

At the end of the work, all errors will be indicated on the tab "Magazine".

Unlike the built-in CHKDSK command, which we will discuss below, this program erases all data when it checks a flash device. Therefore, before checking, all important information should be copied to a safe place.

If after checking the flash drive continues to work with errors, then this indicates that the device is losing its performance. Then you need to try to format it. Formatting can be normal or, if that doesn't help, low-level.

Our lessons will help you to complete this task.

You can also use standard Windows formatting. The corresponding instructions can be found in our article on how to record music on a USB flash drive for a car radio (method 1).
