You are not alone.  We have had ongoing problems with SDLT media and similar 
errors.  Tru64 server, HP ESL9326 library.  On average, we probably get 2 of 
these a week.

All,

I am perplexed by a problem that appears to be getting worse, not better,
over time.  Media verification failures using brand-new Fuji SDLT tape in a
new SDLT320 drive driven by a known-good SCSI bus and cable.  Below the log
file snippet is a summary of stuff I've tried so far...

Environment:  Solaris 8, running NetWorker 7.1

Sun has recommended that with the latest st driver and patch that no
modification is necessary to the st.conf.  Is that an acceptable
recommendation?   Not sure.

I'm really at wit's end here folks.  Any feedback would be very much
appreciated.  Since I only bought the library four months ago and am
already having problems on my third drive, I'm about ready to tell STK to
swap out the drive for an LTO.

TIA
