Cdrom

and /dev/scdfor SCSI drives with the device number .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:

[root@ebs121 media]# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                      18219452   2487644  14791368  15% /
/dev/sda1               101086     11940     83927  13% /boot
tmpfs                  1521384         0   1521384   0% /dev/shm
/dev/hdc               2850578   2850578         0 100% /media
