We have a 1.9G drive (with which I hope to replace the 1.2G which just died), Maxtor, with Dynamic Disk Overlay, which is something like EZ-DRIVE, lets an older BIOS access a larger disk.

This one only works if you boot from hard drive, then it offers partway through boot to let you press space bar to boot from floppy disk.

I read about this and these things are hard to remove, and can interfere with the use of floppy boot disks and also 'alternative' OS-es, and you cannot remove them with fdisk or format.

I got EZ-DRIVE off with a low-level format but this won't low-level format (on the same computer). The computer BIOS auto-detected the drive but the utility said 'hard disk install failure'.

I am told to use the removal tool that came with the drive - is it somewhere on the drive?

Can I somehow wipe out this monster with dd from BL instead? Where might the DDO be located and can I just write zeros over that part? Is the MBR the first 1024 bytes, or half that? Could I damage anything important, irretrievably, by trying dd if=/dev/zero of=/dev/hda bs=1024 count=1?

Or try bs=512 first? I don't care if Win98 gets wiped off the drive.

I have an 800 number for Ontrack but they will probably say to use Windows and the tool that came with the software for the drive.

The drive crashed while I was trying to copy to it a kernel which I compiled for a 486 with imm.o support.
