OK! I have two identical hard drives one drive good the other is bad. And of course the one that is bad has all of wedding pictures and baby pictures of my girls. I have taken the PCB off the working drive and installed it onto the bad HD. I thought I was in the clear, the bad drive started to spin up but no luck. The drives were bought about the same time, but guess what? The DCM is different! I know that my drive still works but I am need of a pcb with the following specs.

WD6400AAKS
DCM:HHRNHT2CHB
Firmware: 2061-701537-E00 07P

If anyone knows where I can get a pcb I would greatly appreciate it. I don't want to spend an arm and a leg for data recovery.

Thanks,
Brian

You will need special tools to move the contents of the ROM of the bad drive to the new pcb board of the good drive. This is Marvell series drive and swaping pcb is not going to get your data back for you

Thanks Iorana! I have been talking to Sunny and hopefully I can get this issue resolved... I don't want to send my PCB to China but I don't think that I have any choice...

It doesn't work to just replace a PCB, you need to re-flash ROM code embedded, which needs professional tools. With the good drive, you can try hot swap, if luck enouth maybe you will get some data.

Here's the question... If my PCB is fixed on my bad HD by a professional, will the drive work again?


Thanks,
Brian

It is a possibility if nothing in the SA was damaged and it is possible to flash the ROM. The ROM has special codes inside of it to work with this drive. They are unique to each drive. You answer is yes it could and then again no it could not depends on what is actually damaged. WD can be very difficult drives to work with sometime you get lucky on this one.

If the rom on your PCB is corrupted and you transfer it "as is" to other PCB , the new PCB won't work. That's why I need THE DRIVE and THE PCB.

Post a clear picture of your burned (bad) PCB.

here is one of the situations. another is PCB damaged that can't read data from original PCB. so as well is send entire drive out.

There are also plenty of recovery labs who can take care of it more locally

OK! ESS data recovery is crazy! 995.00 for data back up.... CRAZY! I know the PCB is bad, what the he## can I do?

jono-ats on this forum is reasonably local to you, try sending him a PM.
