WD5000AAKS fails to init

[shaun]

Hi all,

I just need your guess on this one: WD5000AAKS, spins up, bangs the heads repeatedly, spins down and up again and finally shuts off completely. No mechanical impact according to customer, temperature problems not to be excluded as it was in an external enclosure.
Weak heads?

Head 6 and 7 could be damaged, remaining heads could be OK, or PCB problems too at this models

Regards

Can you disable the heads that Beto tell, and see iff you can get ID.

PCB problems are a bit difficult to verify on these models, as they don't have an external flash ROM for the adaptive data, and for disabling the heads I would probably need PC3000, right?
If there's a way to rule out known PCB problems withput sophisticated software ( measuring equipment and electronics knowledge are available ) please give me a hint.
Information how to disable the heads without expensive software are also welcome of course

Hi friend,
You are absolutily right .as per my experience if pcb is heated and hard drive spin for some moment than thats the firmware problem(for this family /model no.) and we can get the data back with in 5 minutes after rectify /repair this firmware problem.and our clients will happy at same day.so you dont require to disable the heads and all .as per my experience

As you say it is temperature depended, I would assume a component failure. Does your method mean to copy the firmware from the failed PCB to a good one?

Hi ,
please describe your problem as pcb failure problem is diffrent or pcb heating is diffrent without the component faliure and if you are having the proper firmware tools thats diffrent with good data base.

This is a time, to seek for professional help, sorry to say that.

This problem can be SA, head, pcb related, but most likely head or SA.
You can't help yourself without professional tools and the required knowledge.

Thanks,

SA would be a real problem, as I don't have the typical software solutions nor the experience.
Heads would also be a no-go for me on a 500GB drive. I've done head transplants successfully on some drives up to 120GB, but 500 is another deal, especially as I have to possibility to tell whether it is actually a head problem on this drive.

Additionally, this is WD....
So, don't open it!

Nope, Sir I had my time getting a single-platter WD800 running after a head swap (or better: an almost-all-swap, the flex print to the VCM had blown up )

Yes, but what you can do on a low density 80GB drive is not neccessery works on a high density 500GB 6 head modell.

[shaun]

I doubt that it would work, therefore I don't do it

Hi friend,
As per my data recovery experience for solving this type of problem, first we have to check the PCB. If there is problem in PCB, we have to repair the pcb or replace with same component and at Wd please check the exact model no including DCM. After it , if problem is same then check the firmware problem , if find , repair with good firmware repairer tool. If problem is still there, replace the head of the hard drive. But before opening the hard drive, it should be confirm that hdd has head problem. So we have to test the hdd properly before replacing the head .
So if you find the problems after replace the pcb than send your Hard Drive at your nearest data recovery centre but please check that the nearest data recovery centre is having the appropriate clean room /good firmware tools and the appropriate related tools with lot of stuff including donor drive…
and many of the pro are having this facility including the proper stuff /lab...

[N.C.]

And what about the preamp checking before trying another pcb?

Hi Friend,
Thats very much great for you if you can rectify the orignal pcb or pcb supply section or you know the proper soldering and if you are having that much of knowledge and i always prefer to repair/rectify the orignal parts either that is pcb or any other part of the hard drive..but for more than pcb you have to go at nearest data recovery centre.as you will required more equipments.
