Seagate 7200.12 - 1.0 TB | ST31000528AS | P/N:9SL154-568 | Firmware : CC35 | Data Code : 09456Hi guys Happy new year to you,
I'm pulling my hair out with this drive and just want to know if there is anything I can do before chucking it in the bin

Its come from a external HD and It spins fine and shows up on the pc, it is seen in the device manager and shows up on Disc manager but cant be accessed or formatted??
I have tried to boot off my windows disc and re partition it that way but keep getting errors too.
Is it likely needing a new PCB? I am happy to buy one if its likely to work again.
Is there anything else I can do to try to get it to work?? sorry im a bit of a noob when it comes to HDD
Thanks in advance for your help

Bilko.
