Hi,
Using bacula 5.0.1 on a netbsd 5.0 machine with a Quantum SDLT320 tape 
drive The moving to the end of data is very slow. It is configured as a 
freebsd machine but going by bacula's behavior it is unlikely to be a 
operating system problem as drive works perfectly well in all other 
situations.

When moving to the end of data bacula seems to exam every file on the 
tape. Can any one tell me how to fix this?

  Shown below is the out put from bacula-sd in debug mode.

  .... and so on until it finds the last file written


The device is configured as below, and passes the btape test

   Device {
   Name = BACKUP-DLT
   Description = "Tape drive on backup"
   Media Type = DLT-1
   Archive Device = /dev/nrst0
   AutomaticMount = yes;               # when device opened, read it
   AlwaysOpen = yes
   Offline On Unmount = no
   Hardware End of Medium = No
   Fast Forward Space File = No
   BSF at EOM = yes
}

Any help would be great.
Cheers
Royce brown
