Hello everyone,

When I attempt to use amlabel to label a tape on a Tandberg/Quantum
SDLT 220, it produces the following error:

[amanda@Jupiter amanda]$ amlabel -f DailySet1 DailySet100
rewinding, reading label, reading label: Value too large for defined data type
rewinding, writing label DailySet100, checking label
amlabel: reading label: Value too large for defined data type

On the same tape, (after a mt rewind), I attempted a dump/restore check to
the same tape on the same drive:

[root@Jupiter amanda]# dump -0u -a -f /dev/nst0 -L "Jupiter:/" /
  DUMP: Date of this level 0 dump: Tue Jan 28 11:56:00 2003
  DUMP: Dumping /dev/sda5 (/) to /dev/nst0
  DUMP: Added inode 7 to exclude list (resize inode)
  DUMP: Label: Jupiter:/

[root@Jupiter amanda]# restore -C -D / -f /dev/st0
restore: Tape read error on first record

[root@Jupiter amanda]# mt rewind
[root@Jupiter amanda]# restore -C -D / -f /dev/nst0
Dump   date: Tue Jan 28 11:56:00 2003
Dumped from: the epoch
Level 0 dump of / on Jupiter:/dev/sda5
Label: Jupiter:/
filesys = /
./etc/dumpdates: tape and disk copies are different
Some files were modified!
[root@Jupiter amanda]# mt rewind

Then, i went back to the amanda user, and attempted amlabel and got the
same results:

[amanda@Jupiter amanda]$ amlabel -f DailySet1 DailySet100
rewinding, reading label, reading label: Value too large for defined data type
rewinding, writing label DailySet100, checking label
amlabel: reading label: Value too large for defined data type

Just to be sure, the amanda:backup user has read/write access to /dev/nst0:

[amanda@Jupiter amanda]$ ls -l /dev/tape /dev/nst0
crw-rw----    1 root     backup     9, 128 Apr 11  2002 /dev/nst0
lrwxrwxrwx    1 root     root            4 Jan  3 12:34 /dev/tape -> nst0

...and the tape definition that I use for the SDLT 220 is:
tapetype SDLT220        # what kind of tape it is (see tapetypes below)

define tapetype SDLT220 {
    comment "Tandberg SDLT-220"
    length 96868 mbytes
    filemark 0 kbytes
    speed 9142 kps
}

Does anyone have any ideas? I've tried google searching to no avail...

Thanks in advance for all of your help,
