My new WD SATA 16MB cache 500 GB internal hard drive is recognized by the BIOS, but is not seen in Windows XP. I read the instructions on the WD web page that said to jumper pins 5 - 6 to make it compatible with older mother boards. I did that, but still it is not seen in Windows. The PC is an HP Pavilion a1540n. This is a secondary drive to be used as storage, since the primary is filling up too fast. Any ideas?
The same thing happened to me, but none of the suggestions helped. The disk shows up on the boot up BIOS screen but not on Channel 2 in CMOS. It shows up on device manager, which says the device is working properly, but not on Disk Management. I have a Seagate 750 GB drive that I’ve connected using the same cables, and it works just fine.
