I Came across this script a few years ago when I had a problem with a hdd formatting. Its using the dos debug command. It worked that time and a few times with viruses. Now I'm being told it does'nt work. Even though I dont know how to explain it I know it works. Can anybody explain to me whats going on. Here is the script. -F 200 L1000 0 (ENTER) -A CS:100 (ENTER) xxxx:0100 MOV AX,301 (ENTER) xxxx:0103 MOV BX,200 (ENTER) xxxx:0106 MOV CX,1 (ENTER) xxxx:0109 MOV DX,80 (ENTER) <-- "80" for hd 0, "81" for hd 1 > xxxx:010C INT 13 (ENTER) xxxx:010E INT 20 (ENTER) xxxx:0110 (ENTER) <---BLANK LINE - IMPORTANT! > -G (ENTER) Program terminated normally -(CTRL)-(ALT)-(DEL) Of course this is ran after booting to a dos or startup disc. I know it deletes all partions causer after I run it when I go to format it says there is no partions. Any help is appreciated.
