Ebay or seagate.com may be a solution.
I've used those Seagate portables and 2 have caused problems.
Or disassemble the unit, remove the drive and buy a portable case or USB adapter.

You can use it, just make sure that the polarities are the same as the original.

SOURCE: please i need the power adapter rating for seagate

Have you got the original power adapter?
If so the voltage details are printed on the label on the bottom of the adapter.
If the external USB Seagate hard drive houses a 31/2" drive then it requires an power adapter that provides +12 volts and +5 volts both supplying approx 2000mA of current.
If the Seagate uses a 21/2" (laptop) hard drive then it only requires +5 volts power adapter.
The only problem is the power connector to the external drive, make sure it suits the external hard drive unit and the power pins are correctly wired for the Seagate. If the polarity of the plug is incorrect lt wired (ie reverse polarity) then it could damage the USB hard drive and adapter case.
