A second mount almost always works for me. But I have seen the second mount 
fail and 
then a third mount work.  So if your problem is the same as mine, then the 
issue is 
not that the tape loses its label, it is that the drive doesn't successfully 
load the 
tape sometimes.

I have modified the mtx-changer script so it loads a tape and then tries to 
read the 
label with btape.  If it fails, then it unloads and reloads and tries again.  
If it 
fails again, then a third attempt is made before giving up.  In theory, this 
reduces 
a 20% failure rate to .20 x .20 x .20 = .008 or 99.2% success.

The 20% failure rate is a guess.  I haven't actually counted my successes and 
failures, but if anything I suspect it fails even more often than 20%.
