WIPE OUT : as the name implies, this utility will absolutely WIPE your hard drive. For those
times when an industrial strength cleaner is needed to remove any pesky files Fdisk may have
left behind. A readme file is included in the zip file. WARNING...WIPE OUT will remove ALL data
from the Hard Drive.
DIRECTIONS
1- Unzip file
2- Copy WIPEOUT to a Win9x boot disk
3- Boot with Win9x disk
4- At the A:\> type "wipeout c: /nq /np" (no quotes)
/nq = no queries - you will not be asked if you are sure.
/np = no partitions - this will overwrite the MBR
Press Enter .
Now run fdisk to set up partitions .
When done reboot & format .
