        I'm sure it really depends on the number of mounts and
reads/write cycles that the tape goes through. The problem with the
3590E tapes is that once they are taken out of the library, the number
of mounts is lost, so actual mounts per tape is a pure guess if you have
offsite copypool tapes that you rotate through.

        The last time I looked at the tape warranty and on the
manufactures web site, I got the impression that the average expected
life of a lightly used tape (written once, read only a few times, such
as an archive) to be at least 10 years. 

        We typically re-write all our data to new media about every 5
years when we migrate to new tape media, (i.e. 3590A to 3590E, & more
recently, 3590E to 3592),  so I haven't really worried about it too
much. Oh ya, we also have copypools of almost everything, so that too
takes the worry out of a single reaching it's end of life.

Anybody out there know how long 3590 K series tapes last ( I assume in
years).  I am trying to figure if our recent batch of tape/drive errors
are from tape drives and old tapes.  Seem to be older number tapes
giving the errors, Would appreciate any knowledge on the subject or
direction of where to find the knowledge.

Thank You,
