when try to read any sector:

Starting LBA of RW Request=00000100 Length=FFFFFFFF
ProcessRWError -Read- at LBA 00000100 Sense Code=43110081
SP is invalid
Unrecoverable Error Reported

So far I have tried a donor pcb, Translation Regeneration, s.m.a.r.t clear, disable media cache etc with no luck.
Translator recovery did't work on it.

will highly appreciate any help.
