I've done it at once. So not step by step and no logging.
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.
Will try to log as much as possible.

I've checked the BIOS, nothing related to INT13, just normal settings,
also the Adaptec SCSI BIOS keep INT13 "ON" by default.

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