[KangKung]

Hi

I got ST500DM002, f/w KC48, 500Gb but Capacity 3.86 GB.
- No clicking, spin as normal, no error.
- Drive ready but unable access to UA, SA and terminal.

ID displayed look likes load to ST default, find the attachment.

Googling but nobody solved this problem in detail.

Your help is really appreciated

Thankyou

Did you check if PCB is native?

yeah, either pcb is not native or both heads are weak. 1st one is more probable.

Cannot read data from Media.
Contact point problem or Head issue.
If remove PCB from HDD. Seagate PCBs usualy shows 3,86 Gb
