Re: 6390 data capacity

["Dave Shaw" <daveshaw@xxxxxxxxxxxxx>]

Dan,

There are several 8mm tape densities.  The lowest density, which was used by
the 7208 model 2 (if I'm remembering correctly) would be 3.5GB uncompressed
and 7GB compressed on 160m tapes, although I had always thought that those
older drives wouldn't handle tapes longer than 112m.  The next higher (and
most common) density would be the 7GB/14GB capacity, using the newer drives
like the 7208 model 12 and the 6390.  If your tapes say 3.5/7 then I would
suspect that they might be cheap tapes that aren't rated for the higher
density.  Do they work okay?  When you do a DSPTAP, what's the value shown
for density?
