I was encouraged to see someone reported successful operation of a usb cdrw,
so decided to try my iomega. It's the Iomega CD-RW USB 16x10x40 external
drive.
It reads fine, but won't write.
I'm using RedHat 7.3 with kernel 2.4.18-4. I set up /etc/fstab with this
line:
/dev/scd0 /mnt/usbcdrom iso9660 noauto,user,ro 0 0
When I do cdrecord --scanbus, I get:

When I try to erase a cdrw, I get a message saying it doesn't recognize the
medium (output shown below). When I try to write to a blank cdr disk, I get
a similar message (output from KOnCD at end).
I check the permissions and they appear OK, as follows:
[root@localhost root]# ls -l /dev/scd0
brwxrwxrwx 1 root disk 11, 0 Apr 11 10:25 /dev/scd0
but, when I try to mount it, I get a write protection error, as follows:
[root@localhost root]# mount -t iso9660 /dev/scd0 /mnt/usbcdrom
mount: block device /dev/scd0 is write-protected, mounting read-only
mount: /dev/scd0 already mounted or /mnt/usbcdrom busy
mount: according to mtab, /dev/scd0 is already mounted on /mnt/usbcdrom
Any thoughts as to how I can get this burning?
