Hello,
Drive in topic came with clicking heads.
After replacing heads I could retrieve 75% of important data.
After power reset the drive stays busy and shows :

Rst 0x80M
Spin Up
SpinOK
TCC:0018
Humidity:50.2%
Dither
Dither
Dither
Dither
Last Saved GlobalHeader EraseInProgress:00 DiscDataValid:00
No HOST FIS-ReadyStatusFlags 0002A1A1

I could unlock SA and access sysfiles.
Backed up important sysfiles except 28 ( MRT report read error after 51% of reading )


Any suggestions would be appreciated.
Thanks in advance.

Well,
You Were Able To Save 75% Data After a Head Swap ,Then Why did you not save SA Before That ,As Far As The Problem Now you have is 28 is not reading or might be flag is set ,Clear flag and try other you will have to regenerate the Translator

MRT lab wasn't support unlocking this family. ( Sep. 2019 )

That's why I didn't get a full backup from SA.
