NTI Drive Backup Behavior

I purchased a DVD recorder two months ago and used it to do Drive
Backups. I used CD-R disks for my larger C: partition boot
partition and a DVD+R disk for my other smaller partitions. It took
about twenty CD-R disks to backup my C: partition. Yesterday I
decided to backup my C: partition using DVD+R disks. The software
estimated that it would take three disks to do the backup. I was
watching the football game while the backup was going on. I would
periodically watch the progress of the backup while following the
game. I would have to occasionally move the mouse to turn off the
screen blanking. The backup was moving right along. Finally I saw
the verification screen in progress. The game got exciting so I was
not paying close attention to the backup. When I finally
remembered, the backup had started on the second disk. I wracked my
brain because I did not recall changing the disk. Usually the tray
slides out and waits for me to replace the disk. It backed up
several files and went through the verification. The tray popped
out and the screen asked me to label Disk 3 and insert it. I put my
SECOND disk into the drive and continued the backup. It went
through two "disks" and asked me to label a Disk 5. The backup
finished on the third disk and the report said that it used six
disks.

In further reading, I saw that the Drive Backup creates a virtual
2.88 megabyte drive on each CD so that you could boot from either of
the disks. I do not recall the program doing that when I created a
Recovery Disk set back in December using CD-R disks only on the boot
drive.
