i have a hitachi 60gig 2.5" laptop drive in an external usb 2.0 case that doesn't load properly.

i know this drive worked @ one time because i copied all my music files to it for someone to borrow. now, when i plug it up, i get the "found new hardware" & the "safely remove hardware" icon comes up down by the clock (forget what this area is called LOL)

when i goto device manager, it shows up in disk drives as "disk drive" & says it is loaded properly, but doesn't show in my computer as an available drive.

now i also have a 100gig 3.5" hdd in 5.25" external case that loads properly, shows in device manager & my computer & works just fine.

so what am i missing??? like i said....i know it worked @ one time, so trying to figure out if it is a defective usb case, hard drive, or just a pc glitch.

any help would be appreciated
