So long story short, i RMA a WD Caver Black 1TB HDD 3 times, and all the 3 HDD that i got did not get detected under my UEFI(bios). I checked to see if SATA ports were the problem but nope. I have an SSD (Kingston Hyper X) that is the only drive that gets detected everytime, on all the SATA3 ports. I used different cables on the SSD as well to see if any cable were f'ed up but nope. All the cables and SATA port are good.
So why is it that out of the 3 HDD that i RMA, none of them get detected?
The motherboard is an Asrock Extreme4 Z77. Under the Dr.Debug, i get an A6 which means SCSI detect. << Only get that if i have the SSD connected. If i dont i get A9, which is Start of Setup.
