Hello,

I have a guitar learning CD that I got awhile back. It used to work in
under Wine in openSUSE 10.3. However, when insert the CD into the DVD
drive (same as before), I get the following on 'dmesg'

end_request: I/O error, dev sr0, sector 0

Other CDs work fine. It seems to be just this one CD.

The CD does work in Windows. I used Roxio in Vista to make a copy of the
CD onto a CD-R. The CD-R works in vista but not in openSUSE.

Anyone have any ideas on how I can get this CD to work again. My system:

openSUSE 10.3
KDE 3.5.10 release 23.1
Kernel 2.6.22.18-0.2-default

Thanks.


Make a new copy with k3b, maybe vista made the cd to a windows only disc
:-)

on the same machine or a different one?

Same machine. Works if I boot into Vista (cringe!). If I reboot into
openSUSE 10.3, all I see are those errors in dmesg.

Well, I think the problem is KDE now. I manually mounted the original CD
using:

sudo mount -t iso9660 /dev/sr0 guitarws2nd

Where guitarws2nd is a directory in my CWD.

The CD mounted. If I ommit sudo or "-t iso9660", then it get the same errors
as before.

actually this is what I originally suggested - I must not have been clear.

in your post preceding this one, you were trying to mount an .iso file. I
I don't recall iso files being mentioned before; to mount such a file you
use the '-o loop' syntax but not the '-t filetype' syntax.

you might have a look at 'man mount'.

if you are mounting the cd itself (as opposed to an .iso file), then you
use the 't filesystem' syntax. '-t iso9660' is the standard file system
for cds. (do not add '-o loop'!)

have a look at 'man mount'.

you need 'sudo' because it is an operation done by root.

I don't know what problem you are having with kde. you will have to
explain that a bit more. once mounted the cd should show up on the desktop
somewhere and you can click the icon to view it.

3. As suggested earlier in this post, I used k3b to create a CD but I ran
out of CD-Rs, so I made a .iso instead. I had to set k3b to make a raw
copy. If I told it to a normal copy, k3b would freeze. Once the .iso was
created, I think right-clicked on the .iso, in Konqueror, selected
Actions->Mount ISO. I entered the root password. The ISO still failed to
mount with a non-descript error message dialog (i.e. failed to mount ...).

5. I gave up on the .iso and tried again with the original CD. I did:

# mount /dev/sr0 /mnt/guitarws2nd
mount: block device /dev/sr0 is write-protected, mounting read-only
mount: you must specify the filesystem type

Then I added the iso9660 fs type:

# mount -t iso9660 /dev/sr0 /mnt/guitarws2nd mount: block device
/dev/sr0 is write-protected, mounting read-only

And the CD mounted! I can go into the /mnt/guitarws2nd and use wine to
start the software. This is what I get from dmesg after the successful
mount:

ISO 9660 Extensions: Microsoft Joliet Level 1 ISOFS: changing to
secondary root

I have no idea what the "secondary root" is, but I suspect that is the
problem?

out of curiosity, what was the point of step #3? I'm sorry but I feel I am
being incredibly dense! I thought the problem was mounting a cd. why are
you creating a cd or making an .iso file?

problem with what? you are mounting the cd, right? what is the remaining
problem?

sorry for being so dense, maybe I am getting lost in all the details.

The reason for duplicating the CD using k3b was in the hopes that k3b would
create a CD that would work. Perhaps by ignoring any funky
format/filesystem issues...burn a plain old iso9660 CD.

Though I can mount the CD manually, the problem, as I see it, is that it
will not automagically mount in KDE eventhough the CD used to mount by
KDE before. I'm not sure it's a KDE issue or not though. Inserting the
CD into the drive (while in KDE) causes those read errors in dmesg.
However, they go away when I mount the CD manually.
