Hi Gregor.
I've been through this one many times!
Your problem is that your drive cable is
closing (shorting ) the drive select pins which makes
the drive #2, not #1.
This problem is a real engineering screw-up.
The fix is to either get another cable or to
modify the one that you have.
If you hold the drive with the pins facing you
and the pc board facing down, the offending pins
are the last two on the right.
I modify the cable by using a solder sucker to
unsolder the connection and then using an RTV (slastic)
goo to isolate the last two pins.
Not pretty but it works.
This is almost microsurgery, it would be easy to ruin the cable.
The other way to fix this is to obtain a cable from a thinkpad
caddy where the drive is 2.1 or larger (they eventually fixed this).
Feel free to ebail me if you need more information.
Cheers, Bert
