I've had a manager tell me that we should be discarding our LTO-1 media after
10 or so mounts.  He mentioned that anything over 20 is asking for trouble.  He
said he bases this on prior experience.  I've done some searching for what
could be described as a 'best practice' regarding the expiring LTO media and
haven't come up with anything definitive.  I'm courious what others are doing. 
As for me, I've got tapes with anywhere from a dozen mounts to over a hundred. 
I don't get write errors when I do backups. I don't get read errors when I
duplicate images or perform restores.  10 to 20 mounts seems a bit low.  I'd be
interested in hearing what limits others set before discarding an LTO tape.  
Thanks.
