    This simple program can destroy your hard disk. But don’t worry it will only happens if you run it within your PC with some provisions.

    This is how it works:

    Line1: It loads AH with 5 which means "format track”

    Line2: DL contains Drive number (ex. 0= drive A:)

    Line3: DH contains the head number(in this case it is 0)

    Line4: CH contains the track number (in this case it is track 0)

    Line5: CL contains the first sector to process, here it is sector 1

    Line6: AL contains the number of sector to process (This will process 8 sectors)

    Line7: BIOS Interrupt for a disk access

    Line8: Ending process

    Line9: Int 21 for end process

    It actually format a certain track which will cause that you may not able to use the entire HDD.

    Note: Please don’t use this harm other people’s computer. This is for educational purpose only.
