Hi, I got a 120GB Seagate Laptop hard drive that just suddenly stopped working. It wasn't dropped, banged or anything and was installed in its original machine since new.
I took it out and hooked it up to my USB SATA adapter (that works fine) and my P.C recognized it instantly. However it failed to install and showed the old,' Your new hardware is installed but may not work properly blah blah...'. The disk sounds normal and spinning correctly.
I unplugged it and plugged it in and the sound notification is heard but nothing happens. Also with it plugged in I am unable to open, 'my computer' or 'disk management'. I can open device manager which shows the yellow exclamation mark on the drive. I have tried to update the driver / un-install & reinstall but the yellow baby won't go.
If I disconnect the power then re-power and plug it into a different USB port, it does the same again and fails to install.
I'm guessing that there is a problem with the PCB rather than the disk? If this is the case I will do a dreaded board swap of the same revision as the customer doesn't want to pay for professional expensive data recovery.
Just wondered if anyone else could suggest anything. There are 4 pins on the drive, I don't know what they are for exactly on a SATA.
The Drive is a: SEAGATE ST9120822AS / F.W: 3.CDD / MOMENTUS 5400.3 / 120GB
Any help most appreciated.
