It looks more like a corrupt support (media) rather than a bad file... Have you tried cleaning the heads, check the hmmm what is it DAT? or real tape or??? DAT can go faulty if not properly rewound before loading...
I had a case where a sysadmin was desperate and asked me to help him, when I ejected the DAT to look at its state
I noticed the tape was broken
...
Poor guy was trying for hours...

amtape
AMTAPE(8) System Manager's Manual AMTAPE(8)
NAME
amtape - user interface to Amanda tape changer controls
SYNOPSIS
amtape config command [ command options ]
DESCRIPTION
Amtape performs tape changer control operations. It uses the underlying tape changer script defined by the tpchanger option for a particu-
lar Amanda configuration as specified by the config argument.
Tape changers maintain a notion of the current and next slot for each configuration. These may or may not correspond to an actual physical
state of the device, but do tend to minimize searching through the tape storage slots. If the desired tape is in the current slot, it is
likely the next tape needed is in the next slot rather than at some random position in the storage slots.
See the amanda(8) man page for more details about Amanda.
COMMANDS
reset Reset the tape changer to a known state. The current slot is set to the first slot. Other device-specific side effects may occur.
Some gravity stackers need to be reset to the top position by hand. This command notifies Amanda the stacker is back in that posi-
tion.
eject If a tape is loaded in the drive, it is ejected and returned to the slot from which it was loaded.
clean If a cleaning tape is defined for the changer, it is used to clean the drive.
show Show the contents of all slots. This can be slow.
label label
Search for and load the Amanda tape with label label.
taper Perform the taper scan algorithm. Load the next tape in the configuration's tape sequence, or a fresh tape with a suitable label.
device Display the name of the current tape device on stdout.
current
Display the current slot.
update Update the changer label database, if it has one, to match the tapes now available.
slot slot
Eject any tape in the drive and put it away, then load the tape from slot slot and reset current.
slot current
Eject any tape in the drive and put it away, then load the tape from the current slot.
slot prev
Eject any tape in the drive and put it away, then load the tape from the previous slot and reset current.
slot next
Eject any tape in the drive and put it away, then load the tape from the next slot and reset current.
slot first
Eject any tape in the drive and put it away, then load the tape from the first slot and reset current.
slot last
Eject any tape in the drive and put it away, then load the tape from the last slot and reset current.
slot advance
Eject any tape in the drive and put it away. Advance current to the next tape, but do not load it.
This is useful with non-gravity stackers to unload the last tape used and set up Amanda for the next run. If you just use eject,
the current tape will be mounted again in the next run, where it will be rejected as being still in use, ejected and the next tape
requested. Using slot next followed by eject does an unnecessary mount.
Note: most changers optimize the slot commands to not eject the loaded tape if it is the one being requested.
