ftmt -f /dev/nzqft0 status
This is a Conner TSM850R/1700R/TST3200R floppy tape drive, (drive type =
0x0156)
drive status         = 0x00e35965
generic drive status = 0x49000000
(In particular: * at begin of tape * at end of data * tape online * )
sense key error      = 0x00000000
residue count        = 0
file number          = 0
block number         = 0

MTIOCVOLINFO result:
file number          = 0
block size           = 10240
physical space used  =    1.5 gigabytes
real size of volume  =    0.0 kilobytes

MTIOCGETSIZE result:
total bytes on tape  =    1.5 gigabytes
total bytes used     =   29.0 kilobytes
total bytes left     =    1.5 gigabytes

Problem:  We have recently found that we cannot restore from any of our
tapes in rotation; we can restore from a tape
made with same version of  ftape 3.04d and dump from July 1998; so I would
assume this means our tape drive and
installation of ftape 3.04d is stable.

These tapes have been in rotation for a number of months without any
indication of problems until we tried to restore.

I dump to /dev/nzqft0 to get the compression from zftape. I realize that
zftape was taken out; but I haven't had a need
to upgrade since 3.04d was working fine. Last restore in December of 1998
was fine.

Is there anyway to test the media? Here is the message I get when I try to
do a restore:

restore ivbf 10 /dev/nzqft0
Verify tape and initialize maps
End-of-tape encountered
Mount tape volume 2
Enter ``none'' if there are no more tapes
otherwise enter tape name (default: /dev/nzqft0) none
Tape read error while trying to resynchronize
continue? [yn] n

Here are the commands I use to make a backup, the email from the script
shows that the dump takes place
with NO errors:

date
/sbin/swapout 15
echo Rewinding
mt -f /dev/nzqft0 rewind
echo Erasing
mt -f /dev/nzqft0 erase
echo Rewinding to begin Full Backup

I'm looking for alternatives to ftape; I'm beginning to think moving to a scsi
based solution may be better than the floppy drive controller. I would be
interested in hearing comments on this idea.

I expect maybe my media has gone bad; all tapes are kept at the same
place. But find it hard to believe 7 tapes can all go bad at the same time;
and that dumps continue to run and write to the tape but the restore command
cannot read from them.

The other thing that I have noticed is that ftmt -f /dev/nzqft0 fsf 1 now
comes back
with invalid argument. In December, last time I did a restore this worked
fine and moved
between dumps on the tape.

Look forward to any input ftape users can provide.
