Good day.  This is turning into a typical Monday, with plenty of problems 
first thing in the morning.

I came in to work this morning to find the weekend backup job failed.  the 
Status window showed error code 84, and between the event, system, and 
bptm logs, it looks like there was a bad block.  Not really understanding 
what would cause or fix the problem, I power cycled the tape drive and put 
in a different tape, labelling it the same as the one used for the failed 
job.  No media was frozen.  Manually launched the backup, and it failed.  
However, I'm pretty sure this was due to me starting it too soon after the 
drive powered on.  I waited five minutes or so and tried again and it went 
just fine.

Could any of you folks write a few lines lending your knowledge to me?  
I'm wondering what when wrong, and more importantly how to avoid it in the
future.

Thanks very much,
Ron Lyman.
