Hi,
I recently installed Slackware linux 10.1 today, and almost everything works great.

However, I have a minor problem. My IDE DVD/CDROM (set as "slave) drive is marked by /dev/cdrom as hdc, and /dev/dvd also as hdc. This is all fine and good, but my IDE CDRW drive (set as "master") is not detected at all. Also when I got to the device thingie in Konquer, I can not eject, mount, or otherwise access the drive labeled "CDROM".

As far as I can tell, my master IDE drive is not being detected, although at bootup it shows as being loaded. As per the wiki, I did a:
and I get the one marked /dev/cdrom -> hdc, however there is another one called /dev/cdu535 (or something very close to that).

Is there any way to get the CDRW drive to show up/be detected?

check how your kernel recognises those drives:

dmesg |grep hd

or post the output here...

egag

Here is the output:

----------
hdc: LITE-ON LTR-16102B, ATAPI CD/DVD-ROM drive
hdc: ATAPI 40X CD-ROM CD-R/RW drive, 2048kB Cache, DMA
----------

strange, is it possible that those are your two drives ?
if so...i would check the jumpers for master/slave though i
thought it was not possible...

if it's one and the same drive, then the other is not recognised .
maybe check the cables ?

egag

I already did check the jumpers, and unless they are lieing then they are in the proper master/slave position. But no, they are the two drives that I have.

do you have a spare ide cable ?
or do they have also a "cable select " ( cs ) position for the jumper.
if they both have that, try that setting.
my guess is that they both respond when the kernel is looking for hdc.
( never new that it could be )
so i would try another cable or jumper setting.

egag

Out of the clear blue sky (after removing the DVDROM drive), the CDRW drive began responding IF and ONLY IF I am logged in as root. Is there a way to change the permisions on a drive?


Oh yeah, and they both have a cabel select section, I'll try it tomorrow if I can't find a way to make the CDRW work for users.

Ok I tried your suggestion of changing the jumper to cs:

1) It caused an interupt or something to happen repeatedly on boot
2) Fixed nothing =/

If I could just acess the cdrom drive as a user I would be all set

well...how about another cable...?
or connecting one of the two as slave on the HD cable ( it will be hdb ).

egag

7smurfs, do you run a 2.4 kernel with ide-scsi emulation ?
If yes, it is possible that your 2nd drive is recognised
as /dev/sd<number> or /dev/sr<number>

Also what is your output with :
dmesg | grep -i cd
(just the relevant line about drives)

Ok, I disconnected my DVDROM drive, and had to reinstall slackware due to the fact it wouldn't boot up anymore

Well, it is recognized now as a CDRW drive, though I haven't tried burning to it yet. Also, it still won't mount from a user -> how can I change that?

Hello!

Take a look at your /etc/fstab file. For users to be able to mount a CD-roms to have "user" as an option

Example for a line for a cdrom in /etc/fstab:
Here you will find more detailed info abou the /etc/fstab-file:

Thanks Razze, I'll go try it right now.

EDIT: It worked, thanks again!
