My WD10EAVS has got some overvoltage (20V instead of 12V).
Where can I get a new pcb for it ?
Heinz

Have the PCB get burned ?

post a picture, to see the damadge if visible.

no, nothing to see, but the HDD don't work

USB Case is ok, power supply is ok

Maybe chip on block-heads (inside HDD) is damage!! Check it.

do not do that.

Don't open your drive in any circumstances!

Does your drive spin up? Makes any noises?

the HDD is dead

Is your data Important ?

PCB replacement would be a good start, but this model has unique adaptive data stored in processor.
Start by searching TVS chip on this forum.
Do some tests and report your results here.

If you want someone to help you, post a photo of the component side of your PCB.

I mean Check it with analyser!!!

do you want to repair the drive or do you need the data ?

i am in germany maybe i can help. i have two of these drives with working pcb's. anyway posting a photo of hdd's top cover and both sides of pcb does help.

hi i have just finished posting a new topic on the same wd drive. swersig could you tell me if a replacement would work..? you have one..?

well simon75, cant find your new post...

you cant just replace the damaged pcb with any 'looking the same'. you have to make sure that flashed part of firmware on replacement pcb matches firmware on patient platters and of course you have to use the adaptives from the patient drive if possible. so there are two ways:

1.repair the damaged pcb
2.get flash rom content from damaged pcb and write it to another electrical compatible pcb.

solution 1 is often quite simple if only tvs are damaged and the preamp inside the disk is ok but it can be challenging and you may need to know some things about electrics.

if solution 1 does not work you can try solution 2. often you can read the flash rom of damaged pcb with external reader but the pcb needs to have an isolated rom chip (not the case with this disk).

in any case you have to make sure that the preamp is ok otherwise you may damage the replacement pcb and you start all over again. and a defective preamp CAN DAMAGE the data on your defective disk further making it harder if not impossible for a pro to recover your data.

if you managed to get a working pcb but the drive does not id and/or makes strange sounds its definetively a case for a pro and you shouldnt power it on any more.

hope this helps a little...

ps
i have two of these disks (see other topic) with working pcbs but other defects. they are most likely not compatible because there seem to be many different firmware versions for this disk and of course because of the adaptives. i could use my pcbs for building a donor this is why i mentioned it to heinzrm who like me lives in germany. i think there are people living/working more closely to you on this forum.

thanks for the reply. i am trying to look for the tvs('s) now and i cant locate them ill take a picture and post it on my thread. i think admin is checking it before publishing. ??? as i only posted it a couple of hours or so ago. i think the first thing to do is to locate the tvs and then check its resistance. anyone interested please from now refer to my thread. so sorry for hijacking this topic but it just looked like a good place to start..

many thanks swersig

swersig,

I will remove the pcb and scan in both sides and the HDD cover.
I need the datas. My complete bookkeeping is on it, many files of clients (web design), and some other very private files (750 GB). So I don't want to give the drive into other's hands.
When I can rerun the drive, I will backup all files to another computer.

Heinz

well its your choice and i can understand if you dont want to give your drive away. you have a good chance for recovery if it is only damaged tvs otherwise you WILL HAVE to give your drive to a pro since any tingering makes the situation worse. this should be no problem since any GOOD dr company consideres private data private (take a look at the contract). you should only find one with a good reputation. if you change your mind or need help on the pcb just say so.

happy new year,

swersig

It took some time to remove the pcb - no tools ...

Now I scanned the hdd cover and both sides of the pcb.
You can dowenload it from

http://www.enp-beratung.de/downloads/WD10EAVS_1TB.pdf

Once again : the hdd got some overvoltage. 20V instead of 12V

The contacts from pcb to hdd are a little colored ...

Heinz

Check R64 and R67; probably one of them (or both) are open circuit.
Check D4 and D3; they could be short-circuited.
If so, replacing them COULD help, but it could also destroy more and make the recovery much harder.
Since it is your data, you decide

Today i went to an electronic store to repair my harddisk.

It was quite simple. Important are the diodes D3 / D4

D4 was ok, D3 was replaces by a standard diode. After this, the hards disk was running again, with all datas on it .... expense : 10 Euro
