Renaming CD-ROM drive

Brian of Gep · 07-15-2003, 01:42 PM

I have a CD-ROM drive that is located at /dev/hda - how do I tell my computer it is at /dev/scd2?
(I want to do this so cdrecord will recognize it)

Your cdrom can't be located at /dev/hda, that's your ide. Edit your /etc/fstab and add your cd-rom there.

type :
cat /var/log/dmesg |grep hd[a-d]
or something like
/sbin/sfdisk -l
and see where your cdrom is located...

Well, it is set at /etc/fstab to /mnt/cdrom/,
but it isn't detected by cdrecord or cd roast.
the command:
cdrecord -scanbus
returns my DVD-ROM drive, but not my burner, which is on a seperate IDE cable, or my other CD-ROM drive.

Post the content of your /etc/fstab so we can see if something is wrong.

Which of them are working? cdrom/cdrom1/cdrom3. Two of them should be working.

If for example, you're sure that cdrom2 is your dvd. Then change in your fstab your /dev/cdrom2 to /dev/scd2

Brian of Gep · 07-15-2003, 10:21 PM

My DVD-ROM is cdrom3.

My CD-RW drive is CD-ROM.

My CD-ROM is cdrom1.

They all work, and can read CDs perfectly.

But for some reason my burning programs only recognize my DVD-ROM.
(GNOMEtoaster and command-line cdrecord)

(The reason there is no cdrom2 is because I lent it to a friend, who fried it - that isn't fixable)

EDIT: Where exactly do I change it, and why?

Brian of Gep · 08-03-2003, 07:59 PM

Please?

I changed all the /dev/cdromx to /dev/scdx in my /etc/fstab.

EDIT: I rebooted and nothing seems to have changed. I have also gotten a replacement for the fried burner, so now I have all four plugged in and working, but the DVD-ROM drive is still the only one detected by cdrecord -scanbus and GnomeToaster.

DrOzz · 08-03-2003, 08:08 PM

why would you change your mount points to a block device in your fstab? do you mean you made a symlink from /dev/cdromx to /dev/scdx ?
maybe you have to add:
append = "hdx=ide-scsi"
to your lilo.conf or grub.conf depending on your bootloader..

Brian of Gep · 08-05-2003, 12:56 PM

Oops, I meant that I changed the /dev/cdromx, as I had been instructed to.

I apologize, but what is a symlink?

And does it matter where I add
append = "hdx=ide-scsi"
to my grub.conf? Or can it just go anywhere in the file?

DrOzz · 08-05-2003, 01:05 PM

what is a symlink?
just open up your grub.conf file and put it at the end of the file.

EDIT: Stupid post - doing it wrong.
