I know that there is a program that completly write zero's (Binary I/0 0) over everything in a computer, i need it but don't know where i find it. It should be small enough to be installed at an floppy disk.

If you go to the site below it gives you debug routines for doing things like erasing the HDD/partitions/CMOS etc...It would definitely fit on a floppy, debug is around 15K. The cooresponding script file you'd need to write would just be a few K as well. I don't know how complete a job it does. I used one routine I found in the microsoft.com achieves to erase partitions via debug. It works well for me. http://www.computerhope.com/rdebug.htm http://support.microsoft.com/default.aspx?scid=kb;en-us;106419

Go to http://www.jetico.com/ and download BCwipe. install it and copy BCwipePD.exe to a clean floppy disk. Use a bootdisk to bypass harddrive startup. Use bcwipe and do a single (1) pass. and this will wipe all partitions off your hard disk. Multiple passes are recommended to completely destroy Data. Extract from Documentation: Main features of BCWIPEPD 1) The utility is able to destroy contents of whole hard drives, including partition tables, boot records, filesystem structures, operating system files and user files. 2) The utility shredds data according to U.S. Department of Defense recommendations to destroy data (DoD 5200.28-STD): seven pass extended character rotation wiping. 3) Contents of hard drives is wiped without any dependance of filesystem used to format the drives (FAT, NTFS, HPFS or other). 4) BCWIPEPD is designed to provide a high performance of shredding. On modern hard drives performance of write operations is up to 15 MBytes/sec. So seven pass wiping performance is up to 2.5 MBytes/sec.
