And, if you look at a J and a K tape on the notches you will notice that
they have a different configuration.  So, if you put a K tape in a J only
drive, it will kick it right back out.  I thought that all B to E upgrade
kits were K capable.  I did not think that kit came out until the E upgrade
kit for K was available.  If your upgrade kits were installed after July
2001, they just about have to be K capable.

Should see a "2X" sticker on the back of your 3590 drive if it is set to
deal with double length tapes. Also the internal tape spool is green (along
with one or two other internal parts, I seem to recall) so you might be able
to look in through the cooling holes in the top of the case to double check
(if you don't find a "2X" sticker on the drive)

There is a difference between the J and K tapes and the 3590 drives need to
support the extended length tapes.  If the drives are new there is no
problem but older 3590E drives may need an upgrade to support the extended
length tapes.  Check with your CE. Jim Sporer
