When I plug in my portable toshiba hdd (320gb, 2.5" model), it shows up in my computer as a removable media drive. I got the hard drive about a month and a half ago, so I no longer have the box for a return, but just now got around to trying to use it. I'm wondering if there's anything I can do to get it recognized properly, or if it may just be a dead drive.
Check out the manufacturer's website and see if there are any drivers/software available for the drive. If so, install the software, restart and see if the HDD shows up correctly. If not, try plugging it into a different computer to see if it still shows up as a removable media drive. If it does, there is something amiss with it.
