DCM HBBHNTJCHN

Who can sell it to me?

Do you need a same DCM or do you need a hard drive for a recovery purpose?

Do you need for fw or headswap?

A technician said me that heads failed.
So I need to swap platters, and then I have to buy a donor drive.
Someone said me it is important to match not only the drive model but also DCM.

My internet search for such drive failed misarably.

Do you think it is important to match DCM too?

My second question is: it is possible to avoid resoldering ROM with a head swap?
Or head swap is more difficult than platter swap?

Please help a poor guy.

How does the technician know that the heads failed? What are the symptoms? Clicking? What kind of tests did they run? The best solution is to have a donor that matches the whole model number plus the 5th and 6th characters of the DCM. I have had several cases in which a bad PCB caused clicking.

symptoms are clicking. I don't know what kind of test he ran, but the probability of head failing is very high because bios doesn't detect any more hard drive and it was hit badly (sorry for my english).

Before you do a head swap, you should check the alignment - especially if it was dropped. Search this forum for alignment on WD drives. I'd try to re-align and PCB before jumping to heads.

thanks for your reply.

SO you are thinking it is possible that heads are misaligned?

I will search for that in the forum

thanks a lot!
