A USB flash drives stores all the data in its memory similar to a hard drive. The operating system can, later on, fetch this data when required to be accessed. There can be various issues that may turn your USB drive data inaccessible such as if the drive is unmounted improperly from the port then it can lead to data corruption. Another reason for the stored data corruption can be invalid data in the Master Boot Record (MBR) or Partition Boot Record (PBR) or directory structure on the USB drive.

There can be various other reasons also that may make your USB corrupt or unresponsive. This may happen either due to logical corruption or physical corruption. Some common physical corruption issues are broken stems and connectors, dead drives (no power supply), broken circuit or NAND gate, not recognized, RAW, need to format, not accessible, and Dead Drives, etc.

How to Recover Data from an Inaccessible USB Drive?

To recover data from an inaccessible USB or Flash drive, first, you must be able to identify the exact reason leading to the problem while reading the USB drive.

Reasons of USB corruption or inaccessibility can be because of:

Logical Issues
Physical Issues

Recovering Files from Logical Issues

If there are some logical/ software errors with the USB drive, you can easily fix it. You need to repair the file structure so that the USB flash drive can be used again.

This is how you can scan for logical issues using Windows:

Insert the USB drive into the USB port of your system.
Go to This PC or My Computer>Removable Disk icon.
Right click the Removable Disk Icon and open its Properties.
Click on the Tools tab.
Click Check Now button.
You will be given two check disk options “Automatically fix file system errors” and “Scan for and attempt recovery of bad sectors”.
Check both checkboxes.
Click Start. This will initiate the scanning process.
Click Close after the scan process is completed.

If you are using Windows 10 or a lower version then carry out the following steps to repair the USB Flash Drive:

Insert the USB drive into the USB port of your system
Go to This PC or My Computer>Removable Disk icon.
Right click the Removable Disk Icon and open its Properties.
Click on the Tools tab.
Click “Rebuild” button
Let the scan process get completed. Close the scan window once it’s completed.
Right-click the icon of the USB flash drive and “Eject”. Then remove the drive from the USB port.

Now that you have safely recovered the files from the corrupt USB flash drive, proceed further to fix USB drive corrupt due to logical reasons with the following methods:

Recovering Files from Physical Issues.

If you have a physical error such as a broken connector, circuit board, NAND memory chip of the drive, then the hardware needs to be replaced or repaired. Doing-it-yourself can lead to even worse situations. Better you get help from the experts in this area. You can hire any trusted data recovery company like Stellar Data Recovery which is specialized in recovering data from a physically damaged USB drive.

Below we have mentioned solutions to some common causes of physical issues with your USB drive.

a. Broken Stems and Connectors, & Dead Drives (no power to the USB):

A common indication of the physical errors is some kind of error messages or troubles that you see after connecting the USB. Common error messages are “Please Insert Disk into Removable Disk” or “USB Device Not Recognized or Malfunctioned”, “you need to format the disk before using it”, RAW partition, dead or unresponsive drives, and damaged controller chips and/or circuit boards.

If the silver USB connector is broken or the circuit board is damaged it leads to power supply cut-off to the USB. In such case, soldering and circuit repair is required. It’s not advised to do it yourself as if anything goes wrong, you may permanently lose access to your USB and also it’ll reduce the chances of getting your data successfully recovered or sometimes impossible. To deal with above physical errors, specialized equipment and expertise are required. So better you hand over it to some professional and let them deal with the scenario.

b. Error: “Please Insert Disk into Removable Disk”:

This error occurs when the flash drive controller software becomes corrupt. It can also happen if there are some issues with the NAND memory. The above error can be caused by low grade or generic NAND memory chips. With a frequent number of reads and writes, the state of the drive turns worse.

The error indicates that there is some issue with the NAND memory chips. Most probably the metadata stored in the NAND memory is corrupted or wiped and it can’t be mounted then, thus turning the drive unreadable. Whenever you try to read the drive, you will get the error message “Please insert a disk into Removable Disk”. Also, if you try to check the drive size, it usually shows its capacity as 0 MB. As the device cannot be mounted on windows, if you check Device Manager under Disk drives, a different name for the USB drive will be listed. Also, the Disk Management shows a drive letter with No Media.

In such case, you need to search for manufacturers that perform USB data recovery or flash drive data recovery.

c. Undetectable USB Flash Drive:

You may not be able to use your USB drive because of some problems with the USB port, not with the USB drive. So, before performing any repair of the USB drive also make sure that the USB port is working fine.

To test the USB Port remove the USB drive, reboot your computer, and test the USB drive again. See if it works. It is possible that one port may not be working but all others are working fine. So try each port of your computer. If this doesn’t help, try the USB drive on some other computer.

Sometimes, the Installed copy of Windows OS may not be able to recognize your USB drive due to some USB version limitations.

You can fix an undetectable USB Flash Drive by drive recognition:

Go to Start> Control Panel> Device Manager.
Expand the list next to “Disk Drives” option.
You can see a down facing arrow over your USB drive. Double click it and choose the option to “Enable Device“.
Click Next.
Click ‘Next’ again.
Finally, click Finish.

After this, you need to assign the drive letter. To do so follow given steps:

Go to Start>Control Panel>System and Security>Administrative Tools then choose “Computer Management”.
Right, click the USB drive. Select the option to “Change Drive Letter and Paths”.
Click ADD and then click OK.
Now, assign any available drive letter to the USB drive by clicking it.
Right, click the USB to designate it as “Online”.

If this fails, Windows automated “Fix it For Me” service can resolve the issue. If this also doesn’t help, then modifying the system registry will help you tackle the issue. We wouldn’t suggest you go for this option as it may harm your OS.

Conclusion

A USB Drive can become corrupt or unresponsive by any way of Logical or Physical issues. However, you can always securely use a professional USB data recovery tool like Stellar Data Recovery Professional for Windows to recover files after your USB Drive becomes Corrupt or Unresponsive.

I have a dilemma I believe my thumb drive is physically damaged. I plug it in and it is not seen by windows at all…even in the administrative device manager which can locate drives that are not partitioned. The device is not physically broken as per a visual inspection. When I plug it in it gets hot to the touch but no flashing light comes on. Is there any diagnostic than can be done if it is a physical damage issue like a broken circuit?

  Hello Adnan,
  
  Please try these common fixes once.
  
  1) Try plugging in the flash drive into another USB port. If it works that means the problem is with your system’s USB port.
  2) Try connecting the flash drive to another computer.

Hey, unfortunately, none of your suggestments is working in my case.I have USB flash drive.I forgot to eject it and afterward, when I put it back into the computer it says that the file in the flash drive is corrupted.After I tried all of the methods you suggested I end up with a bunch of files with strange names like w6╛ф;┌.╡юО.Then I try with your program that u suggest downloading and after I done all the scans (including the deep one, or whatever its name was) it turns out that all of it was just a waste of time cause in order to recover the files I have to pay almost a hundred.
However, all I want to do is just to delete the files so my flash gets empty and I would be able to use its full space capacity.
Please help me out with this issue.

  Hello Rostislav,
  
  You can scan your drive and check the possibility of recovery by checking the preview of the files. If no preview is available then files are corrupted and they cannot be recovered.
  
  If you do not want to recover the data and wish to delete you files and folders then we have BitRaser for File software which can wipe the data from the drive.
  
  You may check the details of BitRaser for File from the below-mentioned link:

Will your software uninstall cleanly? Or will it run in a VM? I don’t want to install anything on my machine that will be a legacy. I am recovering files for a friend from their hard drive but once recovered I wnat to make sure your software is cleanly uninstalled including all registry keys and hidden settings. Or will “Revo” uninstaller cleanly uninstall it?
Gratefull for a fast reply as I am using someone elses computer for an hour or so,
