Hi

I have a HDD WD800BD-00MRA1 Sata head problem.
I change the head from donor hdd (identical model,firmware,motor number and DCM
all muched except the 2 last digit).
After i changed the head ii used the WD doctor first i got READY status when i
press the load managment i got "WDC ROM MODEL - UNICORN --" (also in BIOS).
Pls i need your advise how to repair and recover the data .


Note: 1- Before changing the head i backup the moduls and track from the donor
hdd.
2- I dont have any donor hdd identically.

Best Regards
