If you can see the drive listed in the bios then the Maxblast software on a bootable cd or floppy should have no problem erasing and reformatting the drive. If not, there may be some bios setting you need to look at, or consider wiping the drive and formatting the drive under windows disk manager....make sure its a basic drive not a simple, otherwise it will not be bootable.....then place the jumper to the master position and reconnect the drive as a master and see what happens....you may have to clear the cmos for it to take effect.
