Yes, that' a nice one too, but this runs instantly instead of off a floppy, making it slightly faster

My typing is painfully slow.  :wink:

[defusion]

this doesnt destroy all data does it?
i mean the overwrite everything with 0's destruction

[Bipolardivide]

Yes, it's a complete 0 write of the drive

Pfft. No error checking really so it's not guaranteed to set all sectors to 0. Add some conditionals, some jumps and some internal routines.

You're looking for something more like:

Code:

   ; Refering to 8-bit reggies for clarity

    mov ch, 0
    mov cl, 1

    .set_to_0:
        mov ah, 3
        mov al, 1
        mov dh, 0
        mov dl, 0
        int 13h
        ; Remember, BIOS interrupts don't work in Pmode
        jc .set_to_0

        inc cl
        cmp cl, 9
        jne .set_to_0
        inc ch
        mov cl, 1
        jmp .set_to_0

... a 5/10 min job I just threw together. Probs will need modding.
