Ubuntu MATE 17.04 and external disc on Firewire port

Hi,

I have trouble with connection of external WD 320 GB HD through Firewire port located on my notebook. The disc is recognized on Ubuntu MATE 17.04 but it can not mount it. Drive’s LED flashes during procedure. External case where disc is located have also USB port and that connection works fine. The trouble is within the Firewire.

Here are the output of following commands:

lsblk:

Disc can be even test with hdparm:

sudo hdparm -Tt /dev/sdb:

If I chmod a-x /lib/udev/scsi_id then the disc is recognized in Caja but it still can not be mounted ( wrong fs …)

May be you can give me any ideas…
Thank you
