WD Black issue

[teerp]

Hello. ( thanks Michael i have emailed you)

I received the new donor today , but unfortunately the drive still clicks. and the bios does not see the drive.

so I presume the preamp is damaged and I need to replace the head stack.

I have a dust free environment box, the type you put your arms through and a glass panel to see through.
so I could attempt a repair, if i had the correct parts and tools.

I think I need to find a duplicate working drive and also a special tool to prevent the heads from touching.

It may be worth a try one day.

I'm sorry that your hard drive still has other problems.
Yes, very likely the pre-amp is burned because i have found on your original pcb the following issue:
1) SMOOTH chip burned (VCM controller).
2) Shorted D3 (5 volt TVS diode).
3) Open R67

You can't fix pre-amp, anybody can't fix. The only way to recover your data is to send the drive to some DR with clean room so that they can change heads.
I'm sorry

If data are really important don't change head stack on your own, let do it to pro.

Hello teerp,

I doon't know from where you are, but I think that yould be the best way to found pro DR near you to recover your data. Otherwise you will spend a lot of money and final result will be, that data will gone and you will have some new knowledge about datarecovery and tools.
Good luck
