A little program I know might be able to fix the file system (as long as you do not use chkdsk first)...

The problem is more likely due to not using the "safely remove" option to eject the flash drive before unplugging it. Have you restarted the system at all since the flash drive was plugged in?

Try restarting the system by first right clicking to remove to unplug the drive and following the restart plug it in and then go to the DM to give it a new drive letter. The files would still be intact but likely it still has a Fat 32 factory format seen. Assigning it a new letter however may initialize the drive for you right away making it available for use.

Windows when not recognising the existing Fat volume on a drive from improper removal will often prompt for a reformat to the native NTFS.

It that happened the drive is likely no good. If you can plug it in on another machine you may filnd it works ok there where you can at least recovery files from it.

Once you have them backed up you simply reformat it to NTFS or better use DiskPart to clean off the factory Fat 32 volume and add a fresh NTFS one. That will show if the drive itself works ok.
