I tried to keep my email short and not write a book describing my problem. 
In doing so most of the replies centered on the cleaning tape being the 
problem. However, the original problem was that the drive would do backups 
fine and then it would refuse to do backups. The first 2 times I had just 
done a restore and then it refused to do backups again. The first time the 
leader came off, I now remember, I put in a SuperDLT tape and the leader 
came off. That tape was ruined and had to be replaced. The next 2 times it 
happened to be the cleaning tape. It seems to me that whatever the next 
tape you put in would cause the leader to come off, but I can't prove it at 
this time. The third time, I had problems, I did a backup over the weekend 
just fine and then on Monday it refused to do backups.
Compaq was here yesterday and gave me a new tape drive. Things didn't go 
well and several processes got hung and I couldn't kill them. In order to 
get rid of them I tried a reboot and then the system refused to boot until 
I turned off the tape drive. I know the scsi id was the same as the drive 
we replaced, we checked that. So, Compaq will be backup today with another 
tape drive. I'll let you know what happens.
Original question:

SuperDLT is so SUPER.

Cheerfulness is contagious, but don't wait to catch it from others. Be a
