wiping hard drive with debug.exe?

Comment:
I am reformatting and reinstalling Win98. Someone suggested to me that prior to formatting, I should use debug.exe (which can be found on a Win98 boot disk) which can totally overwrite the hard drive with random data (to help wipe out anything that may survive a reformat, ie. certain viruses). Then to use fdisk to make a partition, format it, and reload Windows. I'm handy with fdisk and format. The only problem is, I can't seem to figure out the cryptic debug program. What command should I give debug to do something like this (totally overwriting the hard drive with random data). TIA
Here's a debug script that will remove absolutely anything from your drive. Type the following:
debug -F 200 L1000 0 -A CS:100 MOV AX,301 MOV BX,200 MOV CX,1 MOV DX,80 (80 for the main hard drive - hd 0, or 81 for the second hard drive - hd 1) INT 13 INT 20
I wouldn't say "don't bother with debug". A boot sector virus will not be removed by Fdisk or formatting.

I find it hard to believe that a virus (even a boot sector virus) could survive a repartitioning. Repartitioning removes the partition boot code and rewrites sector one (MBR & partition table).

Boot sector is sector 0 (zero).

A boot sector virus will not be removed by Fdisk or formatting. A virus can lock a HD by damaging the volume label... then there's nothing you can do about it... debug is completly neccessary.
