I'm trying to tighten up our process of backing up Sun SparcStations and
servers to Exabyte tapes. I have several questions related to the lifespan
of these tape volumes and ways to avoid unreadable data.

1) What is the expected shelf life of these cartidges?
2) How does the number of times a volume is read or written affect the
   integrity?   (i.e. is there a heuristic in terms of shelf life, write
   access, read access, other variables)?  
3) Is there a certification utility available which would help me anticipate
   tape media failures?
4) Is there a way to keep a count of correctable hardware errors (and then
   junk a volume when an error theshhold is exceeded)?
