drive detail..

MODEL : WD5000KMVW-11ZSMS5
PCB NO : 771814-401

sir can you please tell me which sata card is match on this pcb no thanks..

for PCB 771814, 771820 and you'll need to transfer the ROM chip
or you can convert it to SATA by wiring to E71 E72 E73 E75 and removing C31 C37 C13 C18

i am trying to place 771820 and swap rom but drive not spin up

you swapped the U12 or U14 ? is all pins in good contact ?

yes i swap U12

what REV is the 771814 and what is the 771820
the REV of the donor is a later REV than patient ?

both are REV-A in the embose on the card

Check your soldering work.
And after swapping ROMs, search the forum for manual slow fix for WD.
Good luck
