7200.12 2 platters motor issue

[positivebit]

At power ON drive does not spin and flebily noises 'gn' ... 'gn'... so if motor is seized - but is not.
removed heads motor can spin without any problem manually.
already diagnose PCB and HEADS, they are OK.
resistence on wires looks fine so i would say OHM OK
since have spacer looking for a workaround before platter transplant,
if must be done will be done but you know what i mean

Check if the spindle rotates freely by himself when receives power, instead of checking only by hand.

Do not even start rotate

[dmarques]

If PCB and Heads are tested, so the only chance is damaged spindle.

Another option to platter swap is swap the spindle.

[positivebit]

Platters swapped, but motor still does not rotate and same noises

[dmarques]

So... not a spindle issue... another good conclusion to mess things up

[labtech]

Something not adding up. It seems like the spinning problem carries over where ever the platters go and the platters should have nothing to do with it. WTH?

[dmarques]

So spindle issue is out of question.

I had a case where ROM was the problem.

[positivebit]

Another pcb already tested so not rom related.

[dmarques]

How did you test PCB ?

[positivebit]

Hard drive under recovering problem fixed (after platter swap i badly re-assembly heads and released them near but not exactly in their resting zone causing a micro-stiction )
to say that motor in .12 is not powerful.

Nice

SEMPRE controllare due volte quando riassembli lo stack ! E' andata bene perche' poteva succedere di peggio alla partenza.

ALWAYS double check when reassemblying the stack. Everything went well, at startup a catastrophical event could have happened.

This is the kind of risk that is involved in DIY and is why we discourage users to attempt a DIY recovery themselves. IT really does pay to double check and even triple check!
