Thanks a lot. Just tried to format a 20 GB disk with mke2fs -j /dev/sda1 
- it also hanged the device. So I will format the hdd in a normal way 
(but probably not today, it would require some DIY again), but here is:

Here the numbers from the board:

1. The interface board reads:
2PCB03U-OI30478
IDE---XXX304718
C26

2. The chip reads:
Q811USB
0351WHGA6-24

(I am not sure about the H in the second line - it is written in very 
small letters)

Maybe it is of interest, that my BIOS does not recognize the big 250 GB 
Maxtor which is now in the normal internal IDE slot. The BIOS says 
"none", but FC2 mounts it and I can use it without any problem. So I attach:

[root at localhost root]# dmesg | grep BIOS
