WD Scorpio Blue 640GB WD6400BPVT spins up, 4 beeps, powers down
James
I have a WD Scorpio Blue 640GB WD6400BPVT which spins up, beeps 4 times then spindle powers down. The beeps are in a particular pattern of 3 fast beeps, slight pause then 1 beep. After 5 or so seconds the process repeats. I can hear and feel the motor spinning so stiction out of equation. I removed the PCB and noticed a tinge of brown colour on outer copper pin contacts for heads on the PCB. I’m thinking a heat issue and possibly suspect board. Am I on the right track please?

Hi folks
It appears my second thought was correct, the heads were lodged in the park ramp. Not sure if the platters have been scored in any way as I cannot see any residue inside the drive, however I do realize though that does not mean all is well. Will try to source a donor for heads, transplant and hope for the best. I also managed to retrieve the separated head slider (fat load of good it will do though).
Please don’t roast me for this comment, I know there are some very knowledgeable people in this group and that is why we join to learn from you, but if a drive has two platters will a head stack from another of different capacity with two platters interchange? I cannot recall from Scott’s class or his curriculum if the pre-amp is married to the capacity of the drive?
I’m also still looking to purchase a deepspar does anyone have one for sale?
Have an great weekend everyone.
Jamie

Thanks Loki will check that out.

If the actual platter density has changed then I wouldn't expect the heads to swap.
We match the dcm and everything else as close as possible first.
However...something that does work is using heads from the next larger model.
Example: we have a drive with 2 platters and 3 heads and capacity is 300gb - 100gb per platter.
So we buy the same model with 400gb and we get a 4 head head stack - that will work for 3 and 4 head recoveries...
I hope this helps...

Using heads from the next larger drive makes perfect sense. Thanks for letting me know that. I appreciate the help.

Your asking if you can use heads from a drive with same platters but different capacity.
If the actual platter density has changed then I wouldn't expect the heads to swap.

I forgot to mention I tried cleaning the contacts but the symptoms persist. I'm still leaning towards a controller board but also curious if the heads may have lodged in the ramp. Is this known to occur with this particular drive? The owner has not dropped it as far as I am aware so I can not see this being the case. I will resist opening the drive unless its an absolute last resort.

Having a hard time sourcing a donor for the patient WD Scorpio Blue as follows:
WD6400BPVT–22HXZT3
Date: 14 Jul 2011
DCM: EHCTJBN
Country: Malaysia
I managed to find a possible donor with the following details:
WD6400BPVT-24HXZT1 (at least 3 characters match)
Date: 23 Jan 2011
DCM: HVCVJBB (3rd, 5th and 6th characters match)
Country: (still trying to ascertain)
I note the possible donor is some 6 months older than the patient. Any thoughts on if this will suit?

then it was probably dropped.
There is probably platter damage somewhere.

Platter damage is certainly a concern. On that point anyone know is there a tool available that allows inspection of the space between and under the platters without removing them from the drive? There are some pretty small bore scopes and things available but they are still too large to be of use.

If there is a head ripped off,
then it was probably dropped.

The parameters are certainly very close except for the donor manufacture date which is some 6 months prior to the patient. I managed to match the country also so that might help. I will give it a go and see.

Its hard to say about the donor match, sometimes the only way to know is to try as these rules are to try and deduct the best choice but not always right.

Swapped the heads from the donor. The platters did not look damaged as best could tell. Drive spins up and the head moves but now beeps 4 fast beeps then shuts down. Repeats continually spinning up and doing the same thing. I understand the alignment issue with the top screw over the head stack on the WD drives. Could this be the problem or maybe a bad PCB?

If you find something with close parameters and as close as possible manufacturing date from the same country most chances that the heads will be the same, but WD can change the heads and we wouldn't know unless you already have some pre-knowledge about that from previous experience with same family of drives.

When it comes to head swap compatibility on WD drives is the date really crucial? I’ve done a head swap on this one and think the age difference from my donor to the patient must be too much. Interestingly the rest of the details matched quite well as below:
Patient details
WD6400BPVT–22HXZT3
Date: 14 Jul 2011
DCM: EHCTJBN
Country: Malaysia
Donor details
WD6400BPVT-24HXZT1 (at least 3 characters match)
Date: 23 Jan 2011 (well over 6 months older)
DCM: HVCVJBB (3rd, 5th and 6th characters match)
Country: Malaysia (match)
Symptoms
The drive spins up, head moves, 4 beeps then shuts down. I thought that was normally indicative of head failure. The heads have come from a working donor so I am leaning towards an updated component on the assembly line on this one. I’m thinking about the pre-amp. Could it be the head pre-amp has changed during the 6 + months?
I don’t have a deepspar yet unfortunately. Quite stuck on this one, any clues?

Really need to be closer than 6 months....try 2 weeks or less

Head Stack Assembly Exchange Part Requirements
1. First part of model number and 2 or 3 middle characters of the second part. Example: WD6400AAKS-65A7B0, WD10TMVW-11ZSMS1
2. Country of Manufacturer. Example: Product of Malaysia or Made in Thailand
3. DCMs 5th character. Try matching 4th, 5th, 6th, 7th character if possible. Example: EANNHV2MA
4. Closest date of manufacture possible. Preferably within 3 months.
The easiest test would be to see if you can put the heads back on the original drive and have full functionality. These drives can be very finicky when you put the cover back on. You can follow these suggestions from Frank Meincke which are very helpful:

Good luck.

Thanks for the help. I did try putting the heads back into the donor and it did not work unfortunately. I might try the torque sequence provided by Frank first and see how that goes. That sequence seems like it is very relevant as I know with a drowned WD drive I did it took a long time of tweaking the tension on the cover to get it to fire up in windows. Failing that I will source another donor. Are there specific torque settings for these WD drives? Judging by feel it only seems to be a couple of pound at most.
Thanks again for the help
