And I found if I have 2 partition in the drive, the logical drive space GO WRONG everytime (FDISK 1.2.1), it shows 2% only, if I enter 100% it shows "divided by zero" and return to DOS prompt.

I've checked the BIOS, nothing related to INT13, just normal settings, also the Adaptec SCSI BIOS keep INT13 "ON" by default. >An interesting point arises from this; as discussed earlier, the o/s >would usually go on a mirror.

I don't know the exact answer, by theory MBR should exist on the other disk as a "parity".
