To throw some more into this.

I have just installed FC4 and have had an issue with a USB HD that I was 
trying to mount.

In the past I was having problems with various USB sticks where they 
would not mount on FC1.

My procedure was to open a terminal window and run tail -f /var/log/messages

Plug the stick in and see what happens and what messages I get.

I found that all my stick problems were related to no filesystems. 
There were file systems on the sticks but they were not readable by 
Linux.  On an empty stick, fdisk the disk on the device that was 
indicated in the "messages" listing.  Delete all partitions and create 
the necessary vfat partitions.  Make the file system and all worked well.


Here is an example of what happens when I plugged my stick in.

Hope this helps.
