Rein Stop driving it löppt ..

not. X)
The CD is to start in 8cm format and the slot-in drive can thus nix.
After a bit of googling I found yet the driver and the device works.
Attached hard drives go almost as fast as eSATA port directly on connected devices -> matches.
The piece looks at approx 4mm out of the PCMCIA port, unfortunately locked not, can be pulled out to easily.
After a little tinkering, too, is no more a problem anymore.
