Problems with Dynamic Drive Overlay

By jeremy ·
I am trying to configure a 233 system to run with a 540MB Conner hard drive as the slave. The drive used Ontrack's dynamic drive overlay, seemingly because it was in an old 386 pc that would not support the 540MB size. Anyhow, now that I am using it in a system in which the BIOS supports LBA, how do I remove the DDO so that I can use the drive in windows 98? It is currently not showing up with the DDO installed.

fdisk should remove all partitioning details.
if problems within 98, then create a boot disk that has the fdisk.com executable, boot from that - run fdisk - dont forget to change to the problem disk within fdisk then remove all partition details.

reboot Pc, assign drive letter and format disk

good luck!

Get a DOS boot floppy with DEBUG.EXE on it and follow the instructions at this site: http://www.computerhope.com/rdebug.htm#3

(Repeated below for simplicity, but there are text formattings that are lost.)

This routine is useful in clearing DDO. If this routine completes successfully it will erase everything in Sector 2.

In the following debug routine only type what is in bold from line 3 to 9 you will get a response if it corresponds with the following type the text after the response without putting in a space between the response and what you type in.
