Unable to Read USB Flash Drive

I have a 512MB PNY Attaché USB flash drive. Have been using it without any problems until recently. I am running WinXP Pro which recognizes the drive as H: but when I try to open the drive I get " Please insert a disk into drive H:".
Have I lost everything? Is the drive no longer functional? I am not sure how it got this way we had some power failures recently while it was plugged in and running. Obviously I can't insert a disk.
Any help would be appreciated.

Same with my Lexar jumpdrive...

Same thing happened with my Lexar jumpdrive. My computer says it's not formatted.

Just came back from plane trip. Could security equipment at airport wipe out jumpdrive? J2

I have a 512MB CRUZER MICRO USB flash drive. I can,t open and look dobles

Just an idea...but have you tried putting it into other usb slots in your computer? I remember when I had a Sandisk usb, It would not read @ the front of my bay, but only @ the back.

I have seen that same exact thing before myself. With the 256 Cruzer Mini on several POS Dell's at work.

x-rays do not affect thumb drives.

I have a 1GB SONY Micro Value USB flash drive. I used it for few days every thing was ok. My systems is a WinXP Home Edition which recognizes the drive as E: When I try to open the flash I get a message " Please insert a disk into drive E:".

Please how can I make this flash to work again so as to recover my data?

Please help

Isaac...........Welcome to Techspot!!!

Have you read the link that Tedster posted above??

So you're saying it's a FAT32 problem since XP is using NTFS it might not open the these USB drives after sometime of use. Still if you can't solve the problem a lot of these USB drives comes with 3 years free replacements or just buy a newer one. I know I almost drop the bomb when my PNY fell into well lets say bowl of water sounds better . It just floated so I was sure luckly my data it go down the drain..

well, i have a 128mb memory stick(manutan international-printed on stick) and it has worked fine untill a few weeks ago. my friend thinks he may have done something to it.
Anyway, it reads it in my computer, but when i try to open it, it says
Please insert a disk into drive e.
it always says this. when i right click on it and select format, nothing happens. but, i have opened my computer management from my computer and now i dont have a clue what to do.
Please can someone explain what i need to do, or any other ways of getting it sorted.I do need this memory stick.

Thanks

My computer crashed and burned the day after I

posted my question, so I had nothing but an old cd backup.

Still don't know what caused my stick information to crumble.

Was able to reformat my lexar but now back up everything TWICE.

They say 3.5" floppies aren't reliable but I never had trouble with any of them all the years I used them. J

again I state:

Lots of respect.
