Hello Guru's

I received WD5000AAKS which is dead. Drive is not spinning. I need some help with diagnose the drive.
So far checked all the DIOD's (D3, D4) and registers( R67 and R64) all seems to be fine.
I connected drive to SD Compass and it show ready, but drive is not spinning and voltage show fine on PCB.
I am not sure if issue is with PCB? or the internal motor? How can one diagnose this issue?

When I remove the PM2 jumper, drive spins for few seconds and then stops. ( not sure why it spins when jumper is removed? )

Any help or clue is appreciated..

PCB: 2061-701477-800 AF
DCM: DBRCHV2CBN

Thanks

The PM2 jumper enables PUIS (Power Up In Standby).

See sections 4.20, 4.19.4, 7.52.7, 7.52.8, 7.18 (bits 5 & 6 of words 83 & 86) of the following document.

Working Draft ATA/ATAPI Command Set - 2 (ACS-2):

Thank for Document.

This drive was came out of WD my world book NAS box. Box is not working any more. How do I start this drive without external box.

Given the command in the document, how to use this?

Thanks for your help.

The SD Compass is for cloning good drives. Your drive has other problems on it. You need other tools to determine what your problems are before going on with this one. If you think the PCB is good then it can be internal and you need to determine this one before proceeding on. When you say it comes ready does that mean it is spinning up and clicking like three times and tries to do this repeatly 3 times then comes ready and you have no more spin up on your HDD? Normally this is common issue with WD and you need to understand this and how to go from there to fix this problems. The SD Compass can not do this one for you sorry.

I gone through the document from fzabkar. It make sense now. It need to SET Command to spin the drive.
Jumper is set to PM2 (If the device implements this SET FEATURES
subcommand and power-up into Standby is enabled, the device shall remain in Standby until the SET
FEATURES subcommand is received to power-on the drive)

Drive does not spin at all. Until unless if I remove the PM2 jumper. When Jumper is removed it spins for couple seconds and then stops.

Question is how to disable this features and how to run this ATAPI command set?

Thanks

The PM2 jumper enables PUIS. It takes precedence over any software/firmware setting. When the jumper is removed, PUIS is determined by the firmware.

If PUIS is enabled via either method, then the drive waits for an appropriate command before it spins up. However, once it spins up, then it does not spin down again unless it receives a power management command, or its own internal APM timeout is exceeded.

If PUIS is disabled in the firmware, then the drive spins up immediately after power-on. The fact that it spins down again within seconds would suggest an internal fault, as stated by poehere.

It seems I found the issue. Need to replace swap a head for this drive.
Anyone know a reliable source in Santa Clara, CA? Who can swap the head for WD drives for a reasonable price?

Thanks

It depends on what you mean "reasonable price" - this series are difficult even for seasoned pros...

Well, we had some bad experiences, with some DR company. They asked for the price to replace the head, we gave them what they asked and in end we did not get any Data or money. There are people, who think they are pro's, but they are not.

It is better to ask in the form, so that someone who has already dealt with a reliable source, who has done head swap.

If someone who knows it is better.

I don't understand the fascination with finding someone in the same city or state... In the US 99.9% of people are going to have to ship the drive and lots of times even if you do deliver it to a location it is just a virtual office who will then ship it to the main lab facility.

Any reputable place should be able to handle that with no problem (Ontrack, i365, Drivesavers, etc.) There are also plenty of folks on the forum who can do it but many/most of them don't advertise their companies here. Personally I have referred or seen referred plenty of people to jono-ats in Atlanta and he always gets the job done.

Indeed. I don't get what's the problem. In any case FedEX or TNT or everything else can ship the drive everywhere.

P.S. in my opinion, many bad experiences should have been avoided if in the first instance people didn't ask or search for the lowest price or try to "pull an easy one" . Real pros are not cheap but do the job AND we say "non si sputtànano" (they don't waste foolishly their reputation)... customers get what they want and most of all WHAT THEY DESERVE (this doesn't mean that getting money for botchered job or job not done is fair - the exact contrary, instead ! )
