Hmm, weird... tapedev should be on a separate line, but I guess something was 
wrong with your copy/paste (?), otherwise amcheck would have choke on it

Anyway, your setup seems to be wrong: tapedev should be a directory containing 
the tapes, not the tape itself, and data must be a sym link pointing to one 
of the tapes. For instance, I have tapedev="file:/backup/archive" and:

amanda@pc-cedric:/home/omer$ ls -l /backup/archive/
total 12
lrwxrwxrwx 1 amanda amanda   21 2007-03-28 07:02 data -> /backup/archive/slot1
-rw------- 1 amanda amanda   15 2007-03-29 17:12 info
drwxr-xr-x 2 amanda amanda 4096 2007-03-27 16:07 slot1
drwxr-xr-x 2 amanda amanda 4096 2007-03-27 16:09 slot2

(don't worry about the info file, it's created by the changer)

I set it up like this (first delete any changer-* file and make sure tapelist 
is empty) :

cd /backup/archive
mkdir slot1 slot2
ln -s slot1 data
amlabel archive archive1 slot 1
amlabel archive archive2 slot 2
...

I think that calling the directories 'slotN' is mandatory, but not sure about 
that
