Unfortunately I have one 120gb seagate alive and a 500gb toshiba dead (disk plate problem). If you manage a toshiba 500gb with circuit board problem you can get the circuit board from me @ your price choice .
Have a Samsung 320gb HDD. Got it in a Sony Laptop and upgraded to a SSD. You can have it for 1.5k+shipping. It is 2.5 years old. There is no warranty as far as I know. Let me know.
