Linux cannot write to, delete files from, or even rename files on a NTFS partition. If you do manage to write to the NTFS partition you will most likely corrupt it, which may be apparent immidately or may take a little time to show up. A gift from Microsoft who hate Linux and seem to be going to a lot of effort to be sure that Linux can't safely write to NTFS. Windows users frequently need a tool to do this, as sudden failures of XP to boot are well known, but the maker hardly wants users to be able to fix XP's mess with Linux. XP users are advised to always have good backups, as XP is not ready for the desktop. Beyond this there is some advice in the wiki on ways to recover files from a XP system (Knoppix can usually read the files just fine, even when XP can't), but they don't involve writing to the NTFS partition with Linux.
