Hi,
Well i use freebsd for sometime and i know many things in here but
 anyway i do NOT consider my self advanced user... So i am sorry if
 i cannot explain my problem properly.
First of all i am running at the moment FreeBSD  5.2.1-RC2 on a DELL
 Latitude C810 Laptop. I have a problem with my sound card it is an ESS
 Technology Maestro3 pci card as FreeBSD recogizes also. The thing that
 makes me worry here is that when in X-windows i open the Info Center
 and press on storage devices section it gives me this screen with
 the storage devices which actually are my partitions or cdroms. (Sorry
 i am no sending a screenshot) so there is the root  /  paritions
 among with /var, /tmp, /usr and /dev. Now all of
 them shows a normal output for usage and  Full% and for size
 but /dev has the following attributes: device: devfs (where others:
 /dev/... are having the path) - Type:  ?  (where
 others ufs or cd9660) - Size: 1024B (where others ..MB
 or ...GB - Free: 0B - Full:100.0% and finaly the Usage bar
 is red and full!
Is this normal?
Yes. Devfs is not a file system that exists on a disk, it is a device 
listing that is organized into a file system hierarchy. It (and procfs) 
are always full.

Yes, devfs is a virtual filesystem, it takes no space on any real device
like a hard disk.  All files under /dev are a special type of file
called character or block device files and have no data in themselves,
but are basically symbolic names for various devices in your system.
Also, as devfs is maintained in memory and all files are created
automatically as hardware appears and disappears, like usb devices, it
only uses as much memory as needed and, therfore, will allways show up
as 100% full.

 (If you have problems understanding what i am describing in this e-mail 
 please let me know and i am terribly sorry)

 Please advice
 Thank you in advance

I sense much NT in you.
NT leads to Bluescreen.
Bluescreen leads to downtime.
Downtime leads to suffering.
NT is the path to the darkside.
