If you're not in one of the scenarios above, you can also apply the tips detailed below to have a try.

Fix 1. Recover Files from RAW USB Drive before Formatting

Applies to: Fix USB becomes RAW.

There must be file system errors on your USB flash drive that make your USB device not recognized as RAW. It could be file system missing, corrupted, or not compatible with Windows.

To repair a RAW USB, all you need to do is to recover data from the USB that is not recognized and then convert RAW to NTFS or FAT32 file system by formatting. Formatting will erase the existing data on your USB stick. That's why you need to perform data recovery first.

To retrieve data from an inaccessible device, you can use the professional disk recovery software - EaseUS Data Recovery Wizard. It perfectly supports deleted file recovery, formatted data recovery, RAW partition recovery, and other data loss situations.

To recover data from the RAW USB:

Step 1. Choose the flash drive to scan.

Launch EaseUS Data Recovery Wizard and choose your flash drive where you lost important files. Click 'Scan' to start.

Step 2. Check and preview found flash drive data.

After the scanning is finished, you can quickly locate a specific type of file by using the Filter feature as well as the Search.

  • Filter: A quick way to your wanted files.
  • Search: e.g. File name/file extension.

Step 3. Restore flash drive data.

After checking and finding lost flash drive files, select them and click Recover to restore. You shall save the found files to a safe location on your PC rather than to your flash drive.

After retrieving all the files, you can now format the USB flash drive and assign a new file system to the device, which will make it usable again.

Fix 2. Update Unallocated USB Driver and Create New Partition

Applies to: Fix USB shows as unallocated space.

If your USB is not recognized by the computer and becomes unallocated space, it probably results from outdated USB driver. Thus, you should try to reinstall the USB device driver.

Step 1. Connect the USB flash drive to the PC

Step 2. Navigate to 'Control Panel' > 'System' > ‘’Device Manager' > 'Disk drivers'.

Step 3. Find and select your USB device, right-click and first choose 'Uninstall' and then choose 'Scan for hardware changes' to refresh the drivers.

Step 4. Restart your computer.

After all the operations, you may find USB not recognized issue is fixed and the flash drive is detected. If reinstalling the USB driver doesn't help, you can recover data from the unallocated space with EaseUS Data Recovery Wizard introduced above and then create a new volume to make it ready for data storage. (The unallocated space will show up as 'lost partition' in EaseUS data recovery software. Choose the right partition to scan and then recover your data.)

To create a new volume on unallocated space:

Step 1. Go to 'This PC', right-click it and choose 'Manage' > 'Disk Management'.

Step 2. Right-click the unallocated space and choose 'New Simple Volume'.

Step 3. Follow the wizard to finish the remaining process.

Fix 3. Change USB Driver Letter to Make It Detectable
