Write Permissions for Devices

I'm running Red Hat Linux 9 with the KDE gui.
My floppy disk drive, CD-RW drive, and USB thumb drives will read, but I can't write to them.
I tried putting an "x" in the write permission box for the floppy drive and my permission reads rw-rw-rw, but when I try to write to the device, I get a message saying that I can't.

Is there a terminal mode command that I can use to give myself write permissions for my floppy disk drive, CD-RW drive, and USB thumb drive?

If anyone knows, a step by step would be appreciated.

Send me an email at

Many Thanks!!

edit your /etc/fstab file and add a umask option for your floppy, cdrw, and usb device. save the changes and mount your floppy, cdrw, or usb device.


/dev/fd0 /mnt/floppy auto noauto, owner, umask=0000, rw 0 0

a umask = 0000 will set the permissions on that drive to 777.

although for the cdrw you don't have to do anything really. you just need to get a cd burning program that will set a "non-root" mode for access to the cdrw. something like xcdroast or k3b does this. others like gnome-toaster, eroaster, etc.. may, but i'm not sure about those.
