Thanks, Barracuda, that must have costed you some time.

I must admit however that I hit my limits of juggling with Linux here. My general understanding of such non-routine complications under Linux simply is not profound enough. I even already have forgotten again how I once managed to mount the HD... I will try once more tomorrow to get the Steam game library accepted on the HD - and if not, it is no big deal since I cannot play my preferred titles under Linux anyway.

If I would have known before, I probably would not have even bought the second HD.
