I have 2 cdrom drives in my machine, one cd-r, one cd-rw. Both are
recognized at boot time as hdc and hdd:
$ grep -e "hd[c|d]" /var/log/dmesg
ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:pio, hdd:pio
hdc: CRD-8480C, ATAPI CD/DVD-ROM drive
hdd: HL-DT-ST GCE-8525B, ATAPI CD/DVD-ROM drive
hdc: Disabling (U)DMA for CRD-8480C (blacklisted)
hdc: ATAPI 48X CD-ROM drive, 128kB Cache
hdd: ATAPI 52X CD-ROM CD-R/RW drive, 2048kB Cache, UDMA(33)
But only one special symlink is created in /dev :
$ ls -l /dev/ | grep cdrom
lrwxrwxrwx 1 root root 3 2004-10-24 21:22 cdrom -> hdc
brw-rw---- 1 root cdrom 22, 0 2004-10-24 21:22 hdc
brw-rw---- 1 root cdrom 22, 64 2004-10-24 21:22 hdd
I would have expected possibly a /dev/cdrom1, which is the behaviour I
have seen before in other distros. Should I normally expect this in
Ubuntu?
One interesting thing, which may be related to this, is the fact I
have never been able to get hdc (i.e "cdrom"), to automount a cd when
inserted in the drive (as defined in the Preferences --> Removable
Storage menu). But hdd automounts a cd without any problem. Not sure
where should I check to try to force hdc to automount disk.
And what I ended up having in my /etc/fstab file is :
/dev/cdrom /mnt/cdrom udf,iso9660
noauto,user,ro 0 0
/dev/hdd /mnt/cdrom1 udf,iso9660
noauto,user,ro 0 0
