Windows 7: Lacie Hard Drive help

Hi everyone! So I have an external hard drive thats a Lacie brand.. I have had it for a while and it works great. I use it for movies for my PS3. BUT lol I upgraded to Windows 7 and I connected my drive to load some files on to it and Windows 7 said it need to "fix" my drive in order for it to work on my computer. So I clicked fix and it took about 3 seconds and it said it was fixed. Now my hard drive isnt showing up on my PC or my Mac or my PS3... Is there any way I can recover my files? Your help would be greatly appreciated!! Thanks you!!!

Welcome to Seven Forums.
Sadly I only have some questions for you.

1.Is it USB powered or AC powered?
2.Is it an IDE or a SATA drive?

The reason I aks is if you can hook it up internally by removing it from the case will it show up then?
Fabe

It can be powered by either or. If I attach it to my computer via USB it turns on or I can power it by AC..

And I'm not sure if its an IDE or SATA.. The name is Lacie mobile drive. Its a small hard drive that I can take with me anywhere I go. like 150 gigs... Let me know if that helps.. Also I dont think i can hook it up internally...

anybody have any solution?? I'm desperate lol
