possible scratched platter
January 16th, 2009, 1:24
hi all
I have recieved a drive for repair HTS541060G9AT00 for recovery that has been in to another recovery company, one of the larger well known ones.
the customer has advised that he has been told the platters are scratched. Upon opening the drive i found some finger prints on the platter but no visible scratches on the top platter. I am not sure about the other platters however.
the drive has a bad click when powered on, after backingup the nvram, finding an exact donor drive ( eact board numbers, model numbers, just different MLC numbers ) i replaced the board, and was able to get the drive to only have 1 click at power on, then it becomes ready, still does not id,
I did a SA check with the results posted below.
My questions are
looking at the reports attached is there any way of actually saying if there would be some platter damage somewhere?
should i look at replacing the heads, i dont really want to loose a working set of heads to this drive?
if i replace the heads wil i need to match the exact MLC number for this drive or can i assume that the above donor with identical board will be ok?
i have inspected the chamber in detail under a microscope and found no traces of anything that would indicate any kind of platter scratch on there.

ok for a start it looks like your drive is beyond recovery point
service area has gone bye bye
as it can not pickup the service area of the drive.
this could be down to possible to other problems
1)logic board is damaged (which is possible not)
2)possible underside of platter is damaged which you can not see. (remove the headstack and see if its bent upwards
3)service area is damage (inner rings which would normal show platter damage)
4)service area of the drive aka Module are destroyed
5)the bottom platter has shifted
i would not waste any more time on this problem
as for opening a drive up and finding finger prints tell you that the company who had it before is not a pro
and is a novice.

Hi thankyou for the reply
With the original board there was always clicking and did not reach ready state.
At least the donor board gets to ready state with no click.
I suspect it isbeyond recovery as you never know the history especially since finger prints were found on the platter so you can imagine what else may have been done.
Looking at the heads under microscope they look perfect and not bent in anyway which is why I didn't want to give up just yet.
As with other cases I have found in the past that sometimes these larger companies have no clue and I have found this accross of repairs and with 2 cars I owned.

After you swapped the PCB, did the heads move out of the ramp?
I've noticed that with the Hitachi J9SA00 series, drives can come ready but nothing is actually read from the platters.
I'll bet you'll see a difference in head behavior upon start-up when you use the original PCB vs. the donor board.

Hi jono ats
It sounds like heads are moving of the ramp I will double chech this to confirm
When I replaced the board with a donor board I did reapply the nvram from the patient board so I currently have donor board with original nvram from patient drive
If I install the original patient board to patient drive there is severe clicking
Thx for reply will keep you posted

hmmm if the head stack is no damaged that means that it wont have any platter damaged
unless the company who had it to begin with has done something to it.
possible shifted the platters out
did they say to the client they can do the recovery or not possible.
this sounds like dirty tricks
