Hi Ralf, here is my config :

Device {
  Name = "Sony SDX-700C"
  Media Type = "AIT"
  Archive Device = "/dev/nsa0"
  Device Type = tape
  Autochanger = no
  Always Open = yes
  Volume Poll Interval = 1 hour
  Removable Media = yes
  Random Access = no
  Requires Mount = no
  Hardware End of Medium = no
  Backward Space Record  = no
  Backward Space File    = no
  Fast Forward Space File = no
  BSF at EOM = yes
  Two EOF = yes
  Close on Poll= yes
  Offline on Unmount = yes
}

To label a new tape I do the following :
# mt -f /dev/nsa0 rewind
# mt -f /dev/nsa0 weof 2
# bconsole
* label
* ....

Regarding the hardware problem I'm 100% sure that it doesn't come from
the SCSI card (I tried with 2 differents, an Adaptec and a QSI), it
doesn't come from the tape drive too because I had the same problem in
the past with a Sony SDX 500C, the medias are OK too (sometimes it fails
with a media that didn't fail in a previous rotation cycle), and I
tested with another SCSI cable too. The only thing I haven't changed is
the SCSI terminator ..
What's strange is that all the it happens randomly (it could run 5+ jobs
without any problem).

Best regards,
Julien
