Hello
>From "man dump":
-a ``auto-size''. Bypass all tape length considerations, and enforce
writing until an end-of-media indication is returned. This fits
best for most modern tape drives. Use of this option is particu-
larly recommended when appending to an existing tape, or using a
tape drive with hardware compression (where you can never be sure
about the compression ratio).
I have Sony DDS DG90M (90m/295feet) data carttridge and:
(ncr0:6:0): "ARCHIVE Python 28388-XXX 5.45" type 1 removable SCSI 2
st0(ncr0:6:0): Sequential-Access
st0(ncr0:6:0): 6.7 MB/s (150 ns, offset 8)
density code 0x13, drive empty
Do I have "modern tape driver" or not? :-)

Box freezes, hand reset.... :( I have 2.2.5-STABLE from 11. jan. 1998.
Thanks for any help,
