- I figured that unless tape drive hardware is what determines where a volume
- begins and ends then fragmentation of volumes could be done. If this is
- the case there has to be some software out there that will do it. If not
- then there should be a way to do it youself (after several hours of
- painstaking coding though).
-
- The reason why I'm so bent on this is because I want to use my new tape
- drive not only to backup my harddrive but also make it sort of a removable
- hard disk that I can throw software on that I don't plan on using for a
- while. I know I could've gotten one of those SyQuest 88MB removable drives
- but when you consider the price difference I went for the tape backup.
