I have got a clicking western digital WD10EARS-00Y5B1. So I searched on the internet for a spare-part .
I searched for model WD10EARS and the DCM code 5 en 6 letter identical.
So I opened the drive and saw that there was a difference for the amounts of heads.
both drives have are 1 TB.
What mistake did a make ?

Trying to fix it yourself . . .

These really cannot be fixed without the proper equipment, knowledge, and experience.

You opened the drive without a clean room number one. Number two you had no idea what you were looking for when you ordered your donor drive. Number 3 you opened your donor drive. Number 4 not all drives that click are head problems and you need to understand what is wrong with this drive first and proper diagnostics is needed before you order a part or even open a drive up. I think you can understand you made a lot of errors on this one and there is no need to go on much more. Now recovery will more than likely cost you a lot more becasue this drive has been exposed and not in a clean room and this will give you a lot of problems.

Two : thinking you could do it and trusting the internet .

I opened it in a cleanroom.
I worked 5 years ago in a datarecovery company
I found out my mistake I thought de firts part was only important like I said it was 5 years ago.
I have to search for WD1010EARS-OOMVWB0

The last part -OOMVWB0 should everything match ?. or is it enough to match only certain positions ?

Setting aside any further criticism, are you aware that: 1) the problem may have been the PCB; did you eliminate that possibility first? 2) replacing the entire head assembly at the outset makes it extraordinarily difficult to achieve any recovery; 3) although there are multiple heads it's possible that not all of them are bad; those good heads could be read before replacing head assembly (of course, this requires specialized professional equipment); 4) finding a 100% compatible set of heads that will suddenly allow you to read your data is a dream. Although nothing said here will probably dissuade you, I think you've made a not-necessarily-too-bad situation far worse for yourself. I'd save my money and not bother ordering additional head sets because I don't think you can pull this off.

@ msurgeon:

Sometimes a fellow gets lucky. Here is one that I'm imaging on all heads today:

PATIENT:

Model: WD10EADS-00P6B0
DCM: HBRNNT2CHB
PCB: 2060-771640-003
Date: 12 MAY 2011

DONOR:

Model: WD10EAVS-00M4B0
DCM: DHRCNT2MBH
PCB: 2060-771640
Date: 08 JAN 2010

Well, you hit on the lucky exception rather than the rule. Also, I don't believe you can equate this person's skills set with that of a professional. However, as I said in my previous post, I don't believe anything said here will dissuade him from going forward. And, as we say in the DR biz "hope springs eternal".

@msurgeon

Good point. I'm doing folks a disservice by implying that head swaps are doable without a lot of specific knowledge and experience - not to mention a clean room environment and the proper tools.

In almost every case, an amateur attempting a head swap on a WD drive will fail.

I think that with WD, for example, it takes YEARS of practice & study to reach reasonable competency. Training can shorten that interval, but the self-taught route is long.
