Am currently using a Asus mobo and a seagate 7200.12 1TB (that the mobo detects correctly).
However when I try to add a new sata hard drive, the bios detect only the new drives and not the original seagate drive. And it can only detect one sata drive at a time (i.e even if I plug in 3 drives, only 1 drive will be detected).
I have updated to the latest asus bios. The seagate is plugged to sata port 1 and the other drive, sata port 3.
Might anyone have any solution to the problem? Appreciate your advice!
