It's common for there to be an abundance of /dev/nodes for all sorts of 'devices' you do not have, and it is also common on many distros for there to be a whole bunch of mount points in /mnt and /media that you don't use.
If you do an `ls -l` on the /dev directory, you will see what sorts of
block and
character devices there are in there, such as those /dev/cdrw/ and /dev/cdrom devices; perhaps one of them is a packet device (udf read+write) while the other is a read-only cdrom device. Or, maybe both nodes point to the same thing, and if you're interested, you can find the list of "Linux kernel device allocations" via Google or perhaps on your machine somewhere (like a /doc folder), to identify exactly what type of device each is. You'd want the
major &
minor numbers to figure that out - here's a snippet of my /dev directory:
Code:
lrwxrwxrwx 1 root root 3 Aug 5 12:38 cdr -> sr0
lrwxrwxrwx 1 root root 3 Aug 5 12:38 cdr1 -> sr0
lrwxrwxrwx 1 root root 3 Aug 5 12:38 cdrom -> sr0
lrwxrwxrwx 1 root root 3 Aug 5 12:38 cdrom1 -> sr0
lrwxrwxrwx 1 root root 3 Aug 5 12:38 cdrw -> sr0
lrwxrwxrwx 1 root root 3 Aug 5 12:38 cdrw1 -> sr0
lrwxrwxrwx 1 root root 3 Aug 5 12:38 cdwriter -> sr0
lrwxrwxrwx 1 root root 3 Aug 5 12:38 cdwriter1 -> sr0
# look at all the above 'devices' pointing at /dev/sr0 which is a CD-DVD RW drive..
brw-rw---- 1 root cdrom 11, 0 Aug 5 12:38 sr0
# above is /dev/sr0 which is a block device, major# 11, minor# 0
Hope this helps a bit, but if you tell us what you were trying to 'test' we might be able to offer a particular syntax of burn command to get you the result you want.
