Hi John Please remove confusing references to me and Pen when you're answering Gerald's question. > Windows contains a format command. For example: > FORMAT A: > formats a disk in drive A: > The principle applies to all writable drives in or connected to the > system. Formatting a hard drive does not remove the data! It's easily recoverable. See http://www.webopedia.com/DidYouKnow/Hardware_Software/2005/harddrive_format.asp When you format or reformat a hard drive it doesn't erase the data on the hard drive -- only the address tables. > If you want to remove a partition, a program called DELPART can do that > with one command (highly destructive). > It removes the partition and everything in it.

No, no, delpart does not remove the data on the partition! It's as ineffective in protecting your data as the format command. See http://mirror.href.com/thestarman/asm/mbr/WIPE.html for more info, also about incorrect use of the term "low-level format".
