I'm having a problem mounting my new CDRW DVD in my new machine I just built. The motherboard is an Intel DP35DP, and I connected the CDRW DVD via ribbon cable into the motherboard IDE slot. Centos 5.1 is installed and functioning fine so far (other than this problem).
I can't mount the CDRW-DVD unit. I was able to run cdrecord with the command:
cdrecord -v speed=2 dev=6,0,0 -data /home/mydir/Desktop/backup_bootimage.iso to copy a file that I downloaded, apparently the data copy went fine, but when I ejected the CD and then tried to re mount the same CD to read the file, it would not mount. So then I tried mounting the Centos 5.1 distro disk that I used to install the OS, and am having the same problem with the distro disk. If anyone could give me some suggestions or insights I'd appreciate it. I have provided some data below.
I tried the below commands after ejecting the CD and then executing the commands while the drawer is open, and I got the below outputs:
# sudo mount -t iso9660 /dev/sr0 /mnt/cdrom
mount: special device /dev/sr0 does not exist
And:
# mount /dev/cdrom /mnt/cdrom
mount: block device /dev/cdrom is write-protected, mounting read-only
mount: you must specify the filesystem type
And:
# mount /dev/scd0 /mnt/cdrom
mount: block device /dev/scd0 is write-protected, mounting read-only
mount: you must specify the filesystem type
And:
#sudo mount -t iso9660 /dev/scd0 /mnt/cdrom
mount: block device /dev/scd0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/scd0,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
And:
sudo mount -t iso9660 /dev/scd0 /mnt/cdrom -o ro,unhide
