I could manage to install my first productive FC5 system in a very short time. I am really impressed. The PC is mainly used for making and editing DVB-S recordings. Everything works perfect. With one little exception: My external USB 2.0 disk normally running at about 20MB/s when writing
and 25MB/s when reading on any other Linux system (Ubuntu, Knoppix,
SUSE) reads only at about 11MB/s when reading under FC5. Writing is ok.

Is there a sort of tuning parameter to get this speed back to normal?
