Ahhh, maybe I've already made a mess then. In reality, I only have 7 to 10 
actual backups on each disk. After that, they were full or I had the 
opportunity to send the backup off site, so I rotated to the next one. But I 
pre-allocated 20 'tapes' on each disk. 

Another reason I want to erase them is my backups are growing, so backup #101 
is not going to fit in the space used by backup #1. I need to erase #1 through 
#20 just to be sure I'll have room on the disk for even 1 backup.
