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.
