CD-ROM in Linux

[[email protected] media]# dmesg|grep -i hdc

hdc: ATAPI 1X CD-ROM drive, 32kB Cache, UDMA(33)

The placeholder <medium-mountdir> is used for either <cd-mountdir> or <dvd-mountdir>.

Procedure:

• Log on as user root.
• To create a mount point for the CD / DVD, enter the following command:

mkdir <medium-mountdir>

Example: <medium-mountdir> is /mycd

• To mount the first CD / DVD device, enter the following command:

mount -t iso9660 -r <device> <medium-mountdir>

where:

• <device> is /dev/cdrom for non-SCSI CD devices
• and /dev/scd<n> for SCSI drives with the device number <n>.

Example:

mount /dev/hdc -t iso9660 -r /media

If the file names on the mounted CD / DVD are written in lowercase letters, remount the CD / DVD with the following commands:

umount <device>
mount -t iso9660 -r -o map=off <device> <medium-mountdir>

After the cdrom is mounted you can check with the disk free command (df) that it is correctly mounted at the /cdrom directory:

[[email protected] media]# df

/dev/hdc               2850578   2850578         0 100% /media

#umount /media

or alternatively you can type

#umount /dev/hdc

In case of the scsi cd this is:

#umount /dev/sdc0
