If you haven't already, try formatting the drive via the right-click options menu from within the Computer Management console (right-click the drive under Storage--> Disk Management, and select "Format".)

i tried that on my computer and it didnt work, so i put it on my laptop and formatted it to ntfs and fat32 again. sry forgot to add that in there.

have you assigned it to a different volume letter yet?

[XeCuTiOnR]

yes, i tried that but like on the first pic up there, i r-clicked then change driv letter, then
it said this drive is not accessible please restart computer management, or reboot your
computer, i did both, and no luck. when i install it doesnt install it as a storage device, it
says the usb drive is an unknown device.

Does your laptop have Vista on it?
Try a different thumb drive on the Vista PC.

laptop has xp, and on my computer, i tried a microvault by sony, returned it, and my
mothers drive for her school work, same thing.
YET weird thing that my segate 250gb ex. hd works perfectly fine!, just weird how it doesnt consider my drive to be a storage drive...
