Frozen 7200.10 spindle motor

[crecomp]

Hi guys

i have a 7200.10 Barracuda drive that was dropped during operation.

heads looks fine and no scratches which is a good thing
motor however is jammed solid so i have 2 choices of either moving platters and heads to a different drive or i can try and loosen the motor.

just wanted to know if the procedure for the 7200.7 from pc3000 manual works on this drive of 7200.10 also or not?

i would like to move the heads of the platter before doing any work of freeing motor spindle but as i cant rotate the platters i cant move the heads off, does anyone have any ideas of tried solutions?

thank you for your help

these heads can take quite a pounding so just slide them off. If motor is seized you have no choice. I think a platter swap is your best option.

if u want to take them off the platter u got ony one choice, gently in one smooth move take them off the platter. there is no other options.

Hi

I would try first to unlock the engine as he says the manual, but with very well-taken care of not scratching out platter and damaging head…

Agree with sempre, better to try to free up first...

I don't recommend breaking out the grinder, as suggested in the manual. To many risks and not very professional when the client gets back a hard drive with grinder marks all over it. Moving the platters is your best option...however, the likelihood that one of the platters shifted during the drop is pretty high. So, the odds of a successful recovery is low, especially if you don't have any equipment to realign the platters.

The only lab that I am aware of that is capable of realigning the platters after a shift is Nortek (www.nortek.on.ca). I'm curious to know what other people's success rates are and what you do to detect and correct a platter shift.

I am very close to can say i can handle the platter shifting, missalignment, eccentricity, but yes, the true is the methode is under testing state.
I need some days and some jobs to be sure it is 100% working...

thank you for all replies

i have used the method from manual on several frozen drives that were 7200.7 and all worked well, customers are not concerned about scratches to casing as drives are not used again anyway and all they want is the data.
as i hadnt used this on 7200.10 i wanted to ask and see results.

I am happier to do a swap as there are no spacers involved in this drive so it is not an issue. i am just looking for suitable donor, as the only donor i have is the ST3320620AS, my original patient drive is ST3320820as they are same capacity drives, very similar electronic boards, site codes are different and the donor uses spacers.

has anyone used a different donor as above for this sort of job ?

thx for all replies

Any visually identical chassis will be OK
