Unlike traditional hard disks, USB flash drives are not easy to stop working as they have no moving parts to wear out. But there are still times when USB drives can become corrupted and unreadable as a result of sharing the drive with many different computer systems. Then all data stored on the drive will become inaccessible. Here is a real example:

Hi, I was previously getting a message telling me the drive hadn't been formatted but I think it may have been failing as it's got all my photos on and has been in regular use. I have tried the check disk command but it tells me the drive is RAW(?) which appears to be a problem. I have downloaded Recuva but when I specify the E: drive for file recovery (where my USB stick is!) it says "Unable to determine file system type". Any ideas about what to do next, please?
