Flash drive asks to be formatted, then doesn't appear at all

Hi all:

My flash drive seems to have crashed and I'd like to restore it or recover the files if I can.

It started when I took my flash drive to a Snapy's to print and scan something. At Snapy's, the guy had trouble disconnecting it, and when I got home, clicking on the drive only prompted the message, "You need to format the disk before you can use it."

I tried [Chkdsk /f D:], but received the error message, "CHKDSK is not available for RAW drives."

I took it back to Snapy's, and they plugged it in and messed around a little but couldn't do anything about it. Then when I got back home, my computer wouldn't detect it at all. First, it gave me the "USB not recognized" message, and now it isn't showing up at all. It's like the drive isn't even plugged into my computer.

Anything I can do to at least recover the files from the drive?

Thanks,
Phil

Try partition recovery with the Partition Recovery Wizard in MiniTool Partition Wizard Home Edition 7.6 Free Partition Manager for Window PC | MiniTool Partition Wizard Free Edition

or TestDisk (Windows version) TestDisk - Partition Recovery and File Undelete

A trial using these for partition recovery that should help, here: Recover a flash drive turned RAW – Partition Wizard and TestDisk.
( Read only the partition recovery portions in it. Do not attempt zero-write which I did to convert a good pendrive inaccessible for the recovery trial. You already have a bad drive. )

You can try Recuva and see whether it can see the other files and recover. Recuva - Undelete, Unerase, File and Disk Recovery - Free Download
