I have a Simple Tech Pininfarina 320 GB external hard drive that is no longer recognized by two different PCs, even under disk management. When plugged into the USB, the PCs do try to install the driver, but fails. It is recognized under Devices and Printers as Unspecified and with the information Model-Simple Drive, Category - Unknown, and Status-Software is installing for this drive. The troubleshooter searches for a driver, but does not find one. Basically I get the information that "There is a problem wiht the driver for USB Mass Storage Device. Reinstalling the driver might fix this problem." But I cannot find a driver for this hard drive. Can anyone steer me in the right direction? Thanks in advance!
