I have an older IBM desktop PC that has two partitions installed: One contains my usable Windows XP operating system, the other contains a partition that IBM includes which will reinstall XP for me. I want to reinstall XP using that recovery partition before i give the computer away. BUT, before I do that, I want to completely wipe the XP partition, completely NSA, DoD, whatever, certified wipe that randomizes the partition and overwrites any data on that partition. Then, I want to reinstall the OS, which will be on the old partition that is now wiped over.
I've seen software like Darik's Boot and Nuke which will wipe total, complete hard drives clean. I need some software that will only write over/shred that one partition - I need the other partition to reinstall XP. Does this make sense? Does anyone know of any GNU software that I can download and boot from the CD to do this?
