Why is it not detected?
When I plug in the computer USB port the drive is not detected; the green led blinks and I can hear weak continuous beeps. It is a Seagate 750GB external hard drive.
External storage options by Seagate, usually connected by USB, available in many storage sizes and form factors.
External HD is composed by two parts: a controller and a classic HD. I would try to open it and conect the HD directly to the mainboard with the right interface (sata or parallel) ... if it works by anothe case/controller (very cheap) if it's not recognised ... it's above my knowledge ....
