I did a bit research on it and was able to do a workaround.The issue is caused by the ID string delivered by the disk ( USB 3.5"-HDD), which contains a double-quote character, and this confuses the scripts that auto-mounts the disk and some other things.
I modified the file /etc/inc/func_exthdd.inc to remove that " from the disks name.
Here is the modified file:

I tried to attach the file to the post, but all extensions i tried got rejected, so just copy the text in the code box and save it as /etc/inc/func_exthdd.inc on your MSS2.If you use a windows pc, just ensure you save the file in unix format by use of an appropriate editor ( e.g. TotalEdit etc.) or use the DOS2UNIX tool on your MSS2 commandline to convert the file.Not sure if this will create issues when saved as DOS format, just to be on the safe side.
There are more places affected by the device ID string ( usb device listing and power management in Web UI) unfortunately, so i will have a look if i can fix these as well.
With the modified func_exthdd.inc the TOSHIBA drive got mounted automatically and i was able to run a backup from the web UI, even though the UI says there are no disk drives attached.
Please let me know, if that worked for you ok or if you need some help with this.
