Notice

Before trying any one of the methods of fixing the broken USB stick, please do not format or wipe up your USB stick without backup.

Case 1. Fix the USB with File System Error

Errors would occur when the USB file system becomes RAW. The common error messages include 'the disk is not formatted. do you want to format it now?', 'you need to format the disk in drive X: before you can use it', and 'this volume does not contain a recognized file system...', etc. 

Such a problem will cause data inaccessible. To fix it, you can format the USB drive to a normal state. But formatting will erase all data on the USB. If there is no backup, please use data recovery software to recover data from the RAW USB first and then format it.

Procedure 1. Recover data from the raw USB drive

Download USB data recovery tool - EaseUS Data Recovery Wizard and install it on your computer.

Step 1. Select and scan the RAW partition

If the RAW partition contains a partition label, you can directly select it and click "Scan" to look for the lost files. 

If the RAW partition lost its label, it will be recognized as "Lost Partition", just select the "Lost Partition" and click "Scan" to find the lost data.

Step 2. Preview found data from the scan result

When the scanning completes, find the lost files in "Other Lost Files" folder. You can also use "Files Lost Original Name" or "Tags" to locate the files in RAW partition. "Filter" > "Type" can help you to locate a specific type of file.

Then, check and double-click to preview found files.

Step 3. Recover found data from RAW partition

Select all found files and click "Recover" to get all the data back.

Select another secure location to save the found data and click "OK" to start the RAW recovery.

Case 2. How to Fix a USB that Won't Read

The most common reason why your computer won't read the USB stick is that the drive letter Windows is trying to assign to your device is already taken. To make your USB stick shows again, you just need to assign a drive letter to it.

Step 1. Right-click "My Computer" or "This PC" (for Windows 10) and select "Manage" from the menu.

Step 2. The Computer Management window will pop up. Select "Disk Management".

Step 3. Right-click on the USB that won't read by Windows PC and choose "Change Drive Letter and Paths".

Follow the wizard and assign a drive letter to your 'missing' drive. Your USB drive would read and write properly now.

Case 3. Fix USB Not Showing Up

Sometimes when you insert the USB stick into the computer, it'll not show up as expected. And check the USB status in Disk Management, you can see the USB partition becomes an unallocated space. This problem probably happens because of deletion and virus attack. To fix this problem, you need to create a partition on it.

Step 1. Right-click on the unallocated space and select "New Simple Volume".

Step 2. Follow the wizard to create a partition on the unallocated space.

Case 4. Fix a Broken USB Port

If both restarting or reinstalling USB drivers can not fix the broken device, it's probably related to a hardware issue. For example, the USB port is damaged. There are 3 ways you can try to fix the damaged USB port manually. You can preserve the tutorial graphics to a local drive so that you can refer to the methods anytime.

Case 5. How to fix a bent USB stick

"The USB memory stick was bent in the port, the light comes on when inserted but the computer cannot recognize it... any advise if the information on it can be saved?"

I guess that bending a USB flash device is not uncommon, and the fact is that we don't decide to give instructions here about how to fix a USB that was broken in this way. To tell the truth, without a huge investment in a professional USB repair service, it's beyond repair. Once a USB port is bent or greatly deformed, it's unlikely for a computer to recognize it. The suggested EaseUS data recovery tool can't help, either. It's time to buy a new one.
