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?
