BackupEXEC works on WindowsNT, but I'm not sure if that works with XP. There are a few out there that are made by Veritas, BackupMY PC (I think that's the correct name) is a personal backup software. I think the backup program that comes with XP might also work. From my experience with Python drives (an external and internal Seagate drive), it does not support formatting a tape, but you can erase the information off of it using the software. Hope this helps.
