. . .
DDO is the OnTrack Disk Drive Overlay utility that allows you to use
that larger drive without an updated BIOS.  Your best bet is to remove
it altogether.  Do this by running Disk Manager and choosing the Remove
option.  This will require that you reformat and start over, but the
long term results will be worth it if you have a BIOS that doesn't
require the software solution.  Personally, I prefer to install a drive
controller with a more modern BIOS or just drop in a BIOS card to using
solutions like Disk Manager or EZDrive.  HTH
