Update information:

The problem still isn't solved but I don't consider it as a problem any longer. I'm using floppy discs once more like I've done it before.

I'm guessing that Nigel was right and the K's terminators have to be installed as long as I only use an internal or an external HDD. In that case if I want to use both options (int.+ ext.) then I have to uninstall the K's terminators.

Unfortunality I can't check this statement because I still didn't get a compatible drive. Also I still don't have the required SCSI cable...
