amrecover, extracting the files

[nejat onay erkose]

Hello,

I am stuck in a very basic step of recovering with amrecover.I tried to 
execute amrecover  with: (by the way I use file-driver)

amrecover -C test -d /var/lib/amanda/bande/t12  (where the data that I
want to extract resides in)
(if i don't put -d /var/lib/amanda/bande/t12, it takes /dev/null as the
default tape device.  Am I doing the right thing here?)
and after running amrecover, I always have to change the disk to
/home/noe (the dumped directoy) via:
setdisk /home/noe
The only thing I wanted to do is simply to extract some files from this
dump and as it is seen below at the first line, I have added Capture.png
in to the list...
amrecover> add Capture.png
Added /ReportAmanda/Capture.png
amrecover> list
TAPE test12 LEVEL 0 DATE 2004-04-21
       /ReportAmanda/Capture.pngstill
amrecover> extract list

amrecover: short block 0 bytes

Continue [?/Y/n/r]?
and that is the result, still I couldn't extract the files.

I would be glad,if you could help, thanx!
