I had wd4000fyyz 4TB hard drive which the board burned out due to using alcohol for cleaning. then i replace the board with same REV A brand and transferred the old BIOS to new Board. But when i connect the hard drive to my system it does not detect. But i can fell the board warming up and the disk is rotating. Since the board cannot be detected after few seconds the disk stop from turning. is there anyway still to fix that?

 

Thank you
