I already tried that. The problem is the disk doesn't show up at all in disk management console.
I tried with another extra 250GB disk and the same happens.
Disk1: 80GB, RAID 0 OK
Disk2: 80GB, RAID 0 OK
Disk3: 1TB - doesn't show up anywhere. NVidia nforce control panel reports it as unformated but disk management doesn't see it.
Disk4: 250GB - doesn't show up anywhere.
If I move the disks to the secondary controller they work ok.
The problem is I already have a Raid1 setup in the second controller, so the disks have to work on the primary controler (and they do work in Vista and XP)....
I already upgrade all the drivers
Thanks in advance for your help.
