(AFTER
the tape has been tensioned the first time it is
inserted - which may
take as long
as a few minutes - but can often be done while other
things are
happening - like
booting the OS). In RT-11, I also use VBGEXE to
increase the size of
the
buffers when I do a "/VERIFY:ONLY" command
(yes I know - that notation
can't be used with VBGEXE which requires CSI switches). I may have a
spare
controller. Do you have anything to swap? I may also
have a few
spare cartridges.
The drive uses standard DC600A tapes (1/4" QIC cartridges). The only
drawback
compared to a TK50 is that the capacity is less than 2
RT-11
partitions, but when
it comes to doing a "/VERIFY:ONLY" on a
TK50, it takes so long that I
never
used the TK50 for regular backup, only as an off-site
exchange media.
And then,
a VERIFY operation consisted of doing a RESTORE to a
scratch partition
followed
by a BINCOM with the original file or partition.
