Fix 1. Recover Files from RAW USB Drive before Formatting

File system errors can render a USB drive RAW, meaning that it can't be read by a computer. In this situation, you'll need to recover the files from the drive first, then convert RAW to NTFS or FAT32 format so you can use it once more.

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

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 drive shows as unallocated space.

If your USB drive is showing as 'unallocated space' in the Disk Management utility, then it could be that the driver is out of date or corrupted. To fix this you'll need to install a new 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, then right-click and choose 'Uninstall'. Next, select 'Scan for hardware changes' to refresh the drivers.

Step 4. Restart your computer.

If reinstalling the USB driver doesn't help, you can recover your data from the unallocated space with the help of the free EaseUS Data Recovery Wizard . Then, once they’re safe, you can create a new volume on the drive to make it ready for data storage once more. (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 a drive showing 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 process.

Fix 3. Change USB Driver Letter to Make It Detectable

Another reason that could cause the ‘drive not detected’ issue is if the drive letter assigned to the USB drive is already occupied by another drive on the computer (or the letter on the USB is missing). To solve this problem, you just need to use the EaseUS free partition software to assign an unused drive letter to the USB drive. This should clear the issue and allow you to recover all the inaccessible data with ease.

You can also assign a drive letter to your USB drive by using the Disk Management utility in Windows.

Step 1. Keep your USB connected. Right-click 'This PC' and choose 'Manage' > 'Disk Management'.
