Hitachi DeathStar IC35L030AVV207-0 Help????

Hi all!

Got an interesting case here...

Hitachi DeathStar IC35L030AVV207-0....

Originally knocking/scraping, so concluded heads....

Swapped head (1)...

Spins up OK and calibrates..

But ID not read...

Found NVRAM corrupt..

Swapped PCB from 100% good donor..

Now ID's perfect, all SA modules check out OK....

BUT NO DATA :-(

ALL sectors reporting as "AMN"

This from Universal utility surface check..

Set Max LBA............................. : No restriction
Attrib 5 has value (1) lower than treshold (5)

Tried original PCB back again and re-wote NVRAM, still same.

NVRAM in patient drive was corrupt.

Re-wrote from donor drive.

Worth re-writing from library?
