AFAICS, the difference is that the WriteCache is disabled for /dev/sdb in openSUSE-13.1. Could you try to enable it with hdparm -W1 /dev/sdb ?
Dmesg from boot and 'hdparm -I /dev/sdb' (both knoppix and openSUSE) could be useful as well. Thanks.
Dear Petr, thanks for the reply. After hdparm -W1 /dev/sdb nothing changed, see the attached file. I also added the dmesg and hdparm -I informations you required. Thanks for dealing with the problem.
