I have a dead Seagate hard drive:
Seagate Barracuda 7200.11
S/N: 9QM887J9
ST 3500620AS
P/N: 9BX144-033
Firmware: DE12
Date Code : 09163
I can't see the drive under BIOS, Windows or SeaTools for DOS on either the Dell Desktop PC it was installed or another PC.
Sadly the user who owns the hard drive has no backup whatsoever. Does anyone have an idea how much it would cost to have the data recovered professionally?
