Donor ideal

Hi to all!!

Donor ideal of heads for this model

WD400BD-75LRA0
DCM:HSBHYTJCH
MALAYSIA

In this site(hddguru.com) one sends regards:
country + Forth character in the alphabetic code printed on the label at the rear side od the drive should match

Somebody can here tell its experience with WD? (HEADS)

Thanks advance!!!

He will be that alone God goes to help me?

Internally it has some numeration or characteristic that I can compare with the one of the donor to know itself if head is compatible?
