I didn't see anyone else respond, so I'll jump in with a guess.
Are you sure your  changer script works properly?  Can you
watch the changer while running amcheck and see if it actually
loads every tape?  My guess is that you are just re-reading
the label off the same tape 30 times.

Perhaps your OS doesn't see all the devices.  Linux kernels,
for example, need the option set to scan for multiple LUNS
(CONFIG_SCSI_MULTI_LUN=y) or it will only detect the first
device.
   You should be able to manually control your drives and changer
before trying to debug Amanda, since if the mt (or mtx or whatever)
commands fail, Amanda won't be able to work.
