Hello everybody.
I just move to Slackware 10 and I've been trying to set my system, but I'm having a bad time with my DVD Rom and my CD-R/RW (both liteon).
First I had the idea that Slackware was detecting more device. I got this Idea after checking my dmesg...

Here is a copy of my dmesg file:

hda: ST340823A, ATA DISK drive
hdb: LITE-ON LTR-52246S, ATAPI CD/DVD-ROM drive
blk: queue c03b3360, I/O limit 4095Mb (mask 0xffffffff)

Now I read on a different thread that by editing my fstab file it should work. (assuming that my DVD is on hdd and my CD-R/RW is on hdb). So I changed it. Here is a copy of my fstab...

/dev/hdc2 swap swap defaults 0 0
/dev/hdc1 / reiserfs defaults 1 1
/dev/hda1 /WindowsXP ntfs ro 1 0
/dev/hdd /mnt/dvd auto noauto,users,ro 0 0
/dev/hdb /mnt/cdrw auto noauto,users,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
proc /proc proc defaults 0 0



But still is giving me problems. Now when I try to mount any of them (using the following command: ) it gives me the following error...

/dev/hdd: Input/output error
mount: you must specify the filesystem type


any suggestion????

Although I posted my problem on a different thread I was advice to create a new one, so I'm doing it....

You've got:
You should try:
Additionally, I add nosuid to both of mine, but that is just me.

Change your entries for the CD-RW and DVD-ROM like this:

Thanks for the quick response.
I tried your suggestion (both of you suggested the same thing) and I actually got to see the data on a data CD using both devices but when trying to use a music CD now the error message changed to this...

mount: wrong fs type, bad option, bad superblock on /dev/hdd,
or too many mounted file systems

any idea ???

You can't mount music CDs in Linux - that I know of - at
least not the .cda files. You can play them, however,
and for this I install the xmms-cdread-0.11d.tar.gz plugin
and then just stick them in the drive without trying to
mount them and play with XMMS.

this reply might be a bit late but I had a similar problem. If you are using the 'hdc=ide-scsi' flag with your kernel then to mount a dvdrom I needned to mount it like 'mount /dev/sr0 /mnt/dvd'

hope this helps
