Fix 2: Check Disk Management

If you’ve tried Fix 1 and ruled out the possibility that your USB drive or the USB ports is at fault, you can then check Disk Management to further narrow down the problem. Disk Management is a system utility in Windows that manages all the drives installed on your computer.

Here is how to open Disk Management:

1) On your keyboard, press the Windows logo key and R at the same time, then type diskmgmt.msc and press Enter.

2) Check to see if your USB driver is in which of the following situations:

Situation 1: The USB shows as Raw

Situation 2: The USB shows as unallocated space

Situation 3: The USB shows without a drive letter

Situation 1: The USB shows as Raw

If your USB becomes RAW, it means that there are some system file errors with your USB flash drive. So you should format the drive to convert RAW to NTFS or FAT32. Please note that formatting will erase the data on your USB drive so it’s highly recommended that you use EaseUS Data Recovery Wizard to do a data recovery first. EaseUS Data Recovery Wizard is a professional data recovery tool that supports deleted file recovery, formatted data recovery, RAW partition recovery, and other data loss situations.

IMPORTANT: Once you find your data lost, please DO NOT save, download or install anything to the disk where you lost your data. Since this may very well erase and overwrite the deleted files and reduce the possibility of getting them back.

Here is how to recover data from the RAW USB with EaseUS Dta Recovery:

1) Download and install EaseUS Dta Recovery.

2) Plug your USB drive into your computer.

3) Run EaseUS Dta Recovery, then under External Devices, choose your USB flash drive and click Scan for it to start scanning the files in your drive.

4) Once the scanning process finishes, select the files you want to recover and click Recover to restore the lost files. Be sure to save the files to a safe location on your computer instead of your USB flash drive.

5) Once the files are restored, you can format your USB flash drive, assign a new file system to it to have it back to use again.
