Hello,
I recently had my Western Digital 1200JB-00DUA3 become "invisible" to the BIOS. I was running Windows XP, and without warning, it lost the ability to see my IDE drives. When I rebooted, it did not detect either of them. (I found out later that removing the master IDE allowed the slave IDE to be recognized). I don't believe there's any physical media problems (yet), as there were no unusual clicking sounds or access problems prior the failure. I switched it to the slave IDE position in the first computer, put it into a USB enclosure and tried that in several computers--none of these methods have allowed it to be recognized.
I think (hope) it is a problem with the circuit board. Before sending it off to a data recovery service, I am in the process of obtaining HDs with the same model #, identical LBA #. Most of this effort was driven by this:
http://forums.actionfront.com/showthrea ... t=wd1200jbThe DCM I have heard different things about. Some say the last 3 have to match, others say it does not matter at all:
hard-disk-drives-repair-and-data-recovery-f1/can-i-fix-this-western-digital-raptor-newbie-wd360-t7396.htmlI have also heard that the PCB board model should match, which makes perfect sense to me.
A couple of questions:
1) So does DCM need to match? I read on this post what it stands for:

Thanks.
