Hi
I have this drive from 2020. Client reported that the drive had failed and stop working. After examining I found out that PCB was dead with few comoponets shorted and dead. I swapped PCB with donor same 100% and I have read ROM with external programmer XGECU.Put the ROM on donor and then I found out that heads are dead too. So I swapped head and disk initilze now. I have read SA even it reports me that head 4 is bad. Drive catch ready state but no UA access. I also unlocked ROM and blocked SA writings but still I get abort when access user area. Also I have read 3 files 3f.40,41 SED files and ther was a lot FFFF fields which I tried to fill with zeros and write back to drive but still cannot read user data.
Can you help me with this case?
Thanks
