SOLVED 32 ISSUE AS IT WAS FOUND BAD. Still inaccessible data area.
All critical module looks fine

Can you access any LBA at all?
What is the outcome of a head test?
Are heads still working ok in donor drive?

Used 3 DONOR so far, all with same symptom
Yes, the HEAD is working fine while taken back

The HEADS are working fine without issue.

According to ACE TS - there is an "unknown error code 4593"
