SOLVED: [CentOS] CDRW-DVD Mount Problem, Centos 5.1, Intel board...
Problem has been solved: "sudo mount -t iso9660 /dev/cdrom /mnt/cdrom -o" mounted the drive after adding "mount /mnt/cdrom" to /etc/festab. - Original Message From: Pam Astor <[EMAIL PROTECTED]> To: centos@centos.org Sent: Monday, March 17, 2008 1:45:16 PM Subject: [CentOS] CDRW-DVD Mount Problem, Centos 5.1, Intel board... 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 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/sr0 /mnt/cdrom -o ro,unhide mount: special device /dev/sr0 does not exist Here is info from cat /etc/fstab, cat /proc/mounts, fdisk -l, and cdrecord -scanbus and dmesg | grep -i -e CD -e CD-ROM respectively: >From cat/etc/fstab: /dev/VolGroup00/LogVol00 / ext3 defaults 11 LABEL=/boot /boot ext3 defaults 1 2 tmpfs /dev/shm tmpfsdefaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs/sys sysfs defaults 0 0 proc /proc proc defaults 00 /dev/VolGroup00/LogVol01 swap swap defaults 0 0 >From cat /proc/mounts: [EMAIL PROTECTED]/]# cat /proc/mounts rootfs / rootfs rw 0 0 /dev/root / ext3rw,data=ordered 0 0 /dev /dev tmpfs rw 0 0 /proc /proc proc rw0 0 /sys /sys sysfs rw 0 0 none /selinux selinuxfs rw 00 /proc/bus/usb /proc/bus/usb usbfs rw 0 0 devpts /dev/ptsdevpts rw 0 0 /dev/sda1 /boot ext3 rw,data=ordered 0 0 tmpfs/dev/shm tmpfs rw 0 0 none /proc/sys/fs/binfmt_misc binfmt_misc rw0 0 sunrpc /var/lib/nfs/rpc_pipefs rpc_pipefs rw 00 /etc/auto.misc /misc autofsrw,fd=6,pgrp=2758,timeout=300,minproto=5,maxproto=5,indirect 00 -hosts /net autofsrw,fd=11,pgrp=2758,timeout=300,minproto=5,maxproto=5,indirect 00 fdisk -l Disk /dev/sda: 500.1 GB, 500107862016bytes 255 heads, 63 sectors/track, 60801 cylinders Units =cylinders of 16065 * 512 = 8225280 bytes Device Boot Start EndBlocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 1460801 488279610 8e Linux LVM Disk /dev/sdb: 500.1 GB,500107862016 bytes 255 heads, 63 sectors/track, 60801cylinders Units = cylinders of 16065 * 512 = 8225280 bytes DeviceBoot Start End Blocks Id System /dev/sdb1 * 1 60801 488384001 8eLinux LVM >From cdrecord -scanbus: scsibus6: 6,0,0 600) 'TSSTcorp''CDDVDW SH-S202J ' 'SB00' Removable CD-ROM 6,1,0 601) * 6,2,0602) * 6,3,0 603) * 6,4,0 604) * 6,5,0 605) * 6,6,0 606)* 6,7,0 607) * >From dmesg | grep -i -e CD -e CD-ROM: [EMAIL PROTECTED] etc]# dmesg | grep -i -e CD -e CD-ROM uhci_hcd :00:1a.0: UHCI Host Controller uhci_hcd :00:1a.0: new USB bus registered, assigned bus number 1 uhci_hcd :00:1a.0: irq 193, io base 0x30e0 uhci_hcd :00:1a.1: UHCI Host Controller uhci_hcd :00:1a.1: new USB bus registered, assigned bus number 2 uhci_hcd :00:1a.1: irq 74, io base 0x30c0 uhci_hcd :00:1a.2: UHCI Host Controller uhci_hcd :00:1a.2: new USB bus registered, assigned bus number 3 uhci_hcd :00:1a.2: irq 177, io base 0x30a0 uhci_hcd :00:1d.0: UHCI Host Controller uhci_hcd :00:1d.0: new USB bus registered, assigned bus number 4 uhci_hcd :00:1d.0: irq 82, io base 0x3080 uhci_h
