TOSHIBA 5055GSX ecc SECTORS

[positivebit]

TOSHIBA 5055GSX with a head stiction, after head swap was extremely slow and full of ecc sectors.
Glist not read and not possible to clear it.
Than i swapped secont time, no differences.
THIS behaviour is not localized in a part of the drive, but is the same everywere.

I vote for servo troubles. Dropped drive most probably, I would move the pack (and heads) to WORKING chassis, but I would be EXTRA careful. Further investigation may help....

I've seen this behaviour many times with Toshiba drives, that same pattern on 3K. If you have a ddi then stick it on there, with the right setting it will make light work of it.

On 3K, try setting it to udma 33 and hit the play button to start the copy process. When it starts, power the drive off and back on again with the task still running. Sometimes this is all it needs.

... and what can be the cause ?

Exactly so, had an MK6021GAS today with stiction, easily fixed.

DE did not want to know, loads of errors.

DDI made light work of it and imaged it almost perfectly in a hour or so.

i have tryed Nick_CT smart solution, and it is working - but my drive, that was dropped down, has got too many bad sectors and i have to restart the procedure manually many times - will be a long attended recovery without ddi.
Anyway should be interesting to ask ace support the fixing and the reason..
