Just built a new pc with two sata-2 hard drives. One is 80Gb the other 250Gb, windows XP SP2. On installing XP I put it on the 80 Gb one. System works OK but in 'my computer' the second HDD is not shown. It does show in boot up screen and in device manager so I assume it is not formatted. As I cannot see it how can I format it? I want the drives to operate seperately not as a raid array.
