We had the same problems with a Certance LTO-2 drive. Reason was that
"Fast Forward Space File = yes" didn't work with this drive. Updating
to a an LTO-3 solved the problem.For reference here is my Device
section, the last 5 lines are crucial for drive performance.

Device {
  Name = ArcVaultDrive
  Description = "HP LTO-3 inside Overland ArcVault24 lib"
  DeviceType = Tape
  Media Type = LTO3
  Archive Device = /dev/nsa0
  AutoChanger = yes
  Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
  DriveIndex = 0
  Maximum Network Buffer Size = 65536
  SpoolDirectory = "/var/spool/bacula/data"
  MaximumSpoolSize = 850G
  AutomaticMount = yes               # when device opened, read it
  AlwaysOpen = yes
  Offline On Unmount = yes
  RemovableMedia = yes;
  RandomAccess = no;
  Use MTIOCGET = yes
  BSF at EOM = yes
  TWO EOF = yes
  Hardware End of Medium = no
  Backward Space Record = yes
  Backward Space File = yes
  Forward Space Record = yes
  Forward Space File = yes
  Fast Forward Space File = yes
}

You may consider updating to 6.3 RELEASE/STABLE since you may get into troubles
when running concurrent jobs.
