I know this discussion was a few days back, but ...

I have initialized every tape I have used in the last 16 years here (granted the tape drives have come and gone) with a 2 week rotation of tapes, and monthly and quarterly archive of tapes, with weekly sets going off site.

I have *NEVER* had a tape break on me. Not the 1/2" reel, not the 1/2" cartridge (3590E) not the 1/4" cartridge, and not the 3570.

I have had poor quality tapes go bad, but not usually in the header area.


FWIW

An old time IBM'er once told me that the INZTAP command did an extra erasure
function prior to writing the label info, plus there is some extra
tensioning that takes place. I've had more than a couple of tapes break on
me at client sites where I've walked in behind this one particular software
company's "system setup expert". One of the first things I do for these
clients is to throw out the software company's backup routine and to set the
client up with a backup utility that really works. Sorta helps to follow the
rules in the chart about backing up the right stuff. :-))

The IBM'er in question is now retired, but considering I once watched him
manufacture a jumper for a S/38 circuit board from a paper clip, I pretty
much have followed his "gospel rules".
