problems with data cds

i'm on a two day old installation and using kdemod. when i put in a data cd, the device notifier does nothing. when i put in my slax livecd, it pops up, recognizes slax and asks me what to do with it. if i open a terminal and try something like "mount /media/cdrom", i get a segmentation fault.

here's my /etc/fstab:

#
# /etc/fstab: static file system information
#
# <file system>        <dir>         <type>    <options>          <dump> <pass>
none                   /dev/pts      devpts    defaults            0      0
none                   /dev/shm      tmpfs     defaults            0      0


/dev/cdrom /media/cdrom   auto    ro,user,noauto,unhide   0      0
/dev/dvd /media/dvd   auto    ro,user,noauto,unhide   0      0
UUID=830caa70-c277-4bdc-ae4c-eb7bf3e266bc swap swap defaults 0 0
UUID=910cec06-0466-4326-8a03-77bbbec57190 / jfs defaults 0 1
UUID=ac21aaad-72a7-456f-adf4-cf138287f31f /boot ext2 defaults 0 1
UUID=e966b147-a6d5-4350-a8c4-c0a21d76f049 /home jfs defaults 0 1
/dev/sdb1  /home/fuscia/ext-d  vfat  user,noauto,exec  0  0

when i installed, i let my /etc/fstab be automatically generated, as i've done with all my other arch installations.

this area is pretty much a mystery to me.

i did load my slax livecd to ram to see if that environment would recognize data cds and it did.

Re: problems with data cds

You aren't using HAL? If you do you should comment out cdrom and dvd lines from fstab.

i am using hal (and it is loading upon booting). i commented out the cdrom and dvd lines, but nothing happens. and now, when i do something like "mount cdrom", i get a response that there is no such thing in /etc/fstab.

Re: problems with data cds

Do you start KDEmod from kdm?

If I understand it right, HAL doesn't even give a message that it couldn't moutn because of "bla bla" something. To mount it manually would if there's no rule added to fstab mean you need to specify mount-points, so it sounds to me as correct behaviour.

Re: problems with data cds

no, i use startx. also, i only occasionally use kde (it gets on my nerves, so i dump it and go back to openbox).

If I understand it right, HAL doesn't even give a message that it couldn't mount because of "bla bla" something. To mount it manually would if there's no rule added to fstab mean you need to specify mount-points, so it sounds to me as correct behaviour.

is not "/media/cdrom" a mount point?

/dev/cdrom /media/cdrom   auto    ro,user,noauto,unhide   0      0

at any rate, either way, data cds are not being recognized.

my camera still mounts with "mount camera".

/dev/sdb1       /home/fuscia/camera        vfat        user,noauto,exec 0       0

Re: problems with data cds

You just wrote "mount cdrom"so I thought you hadn't specified a mount-point.

Do you start KDE with consolekit activated? I just tested here at work - yes I'm fortunate enough to be able to use Arch at work - and it has KDE (not KDEmod) started by KDM which activates a consolekit session, and no problem at all to get data-CDs mounted. At home though - Awesome with or without SLiM or CDM - I need to add "ck-launch-session" to ~/.xinitrc, and it works just as well with data-CDs.

Anyway if your camera is mounted automatically I don't know what's the issue. I sounds strange to me that HAL doesn't even react and at least spit out a error message. If HAL is started it should notice when a device is added.

Re: problems with data cds

i still can't get this worked out, but i found a pretty oafish way to work around it - comment out hal in my /etc/rc.conf, uncheck my cdrom entry in /etc/fstab and mount and cp while in the console. i guess it's on a par with grenade fishing, but it does work.

Re: problems with data cds

Since last upgrade (a week ago) I have the exact same problem, it seems to only relate to data cd's??. Nothing happens at all no msg etc.

dmesg returns lots of;

Buffer I/O error on device sr0, logical block 356611

end_request: I/O error, dev sr0, sector 1426440

When I try to manually mount I also get the segmentation fault msg.

I have been able to make an iso of the disk with dd if= /dev/sr0 of=TFT/iso

But this is of now real help.

Hal & I are definitely not friends, he regularly plays up making  my regular upgrades a lottery:-) I suspect he might be the offspring of uncle Bill.

Any help will be appreciated.

Many thanks

Re: problems with data cds

I wonder if this is hardware related, because I've been able to replicate it using a USB optical device. Or that it's some oddity between how discs have been burned and this device.

A disc probably burnt by Nero or Windows own burn functionality works perfectly on regular optical devices I have, but the USB one put out this info repeatedly (similar to the Karenslfs'):

Buffer I/O error on device sr1, logical block 199
sr 5:0:0:0: [sr1] Result: hostbyte=0x00 driverbyte=0x08
sr 5:0:0:0: [sr1] Sense Key : 0x5 [current]

end_request: I/O error, dev sr1, sector 1592
Buffer I/O error on device sr1, logical block 199

Another type of bootable data disc, a Linux distro ISO burnt in K3B, is mounted by HAL perfectly.

Just some input on what I found out, but not been able to put together as a solid explanation.

Re: problems with data cds

I wish mine was since I have exactly the same problem. CD's won't mount either auto or manually yet DVD's will.
I have another computer wth Arch installed and the same issue exist there too.
The assumption is that the problem occurred during an upgrade but since I haven't needed to read a cd in several weeks I have no idea when this happened or what hosed it . (Won't auto mount  and the "segmentation fault" error message when I attempt to mount via the terminal.)

Re: problems with data cds

Im getting the same error here. CDs are not recognised by the system and DVD's are.

Any help??

Re: problems with data cds

A couple solutions to this issue have been posted in the Workstation User forum under the title "cannot mount cdrom".

You can either downgrade a package or apply a patch to the existing offender.   

Good work Matzo, thank you. Read the bug report he gives a link to.

Re: problems with data cds

I don't think this helps:-) but...
I've just burnt a "data cd" with the normal Xfburn & put in a blank cd all seemed well, however the dmesg return still has the same error messages similar to above....

Info fld=0x0
sr 1:0:0:0: [sr0] ASC=0x21 ASCQ=0x0
sr 1:0:0:0: [sr0] CDB: cdb[0]=0x28: 28 00 00 00 00 00 00 00 01 00

sr 1:0:0:0: [sr0] ASC=0x21 ASCQ=0x0

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

also mount returns.......;

$ sudo mount
/dev/sda1 on / type ext3 (rw,noatime,nodiratime)
udev on /dev type tmpfs (rw,nosuid,relatime,size=10240k,mode=755)
none on /proc type proc (rw,relatime)

/dev/sda2 on /home type ext3 (rw,noatime,nodiratime)
gvfs-fuse-daemon on /home/tpg/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=tpg)

i.e. the blank cd is not mounted.

Now I open Xfburn & make a new data CD......
while it's burning dmesg returns the same error............

Info fld=0x0
sr 1:0:0:0: [sr0] ASC=0x21 ASCQ=0x0

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

& mount still returns ....

$ sudo mount
/dev/sda1 on / type ext3 (rw,noatime,nodiratime)
udev on /dev type tmpfs (rw,nosuid,relatime,size=10240k,mode=755)
none on /proc type proc (rw,relatime)

/dev/sda2 on /home type ext3 (rw,noatime,nodiratime)
gvfs-fuse-daemon on /home/tpg/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=tpg)

i.e. the cd is "still" not formally mounted; however Xfburn completed the making of the data CD with now errors returned.

I've just attempted to re-mount this new data CD which was just burnt with Xfburn & again dmesg gives lots & lots of  ..........

mount of course is still not seeing it.

$ sudo mount
/dev/sda1 on / type ext3 (rw,noatime,nodiratime)
udev on /dev type tmpfs (rw,nosuid,relatime,size=10240k,mode=755)
none on /proc type proc (rw,relatime)

/dev/sda2 on /home type ext3 (rw,noatime,nodiratime)
gvfs-fuse-daemon on /home/tpg/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=tpg)

Many thanks (in advance:-)) for any solutions offered

Re: problems with data cds

I don't know if this is relevant, but I had similar issues with burning CD's on my laptop, the CD cannot be read afterwards or booted from, works perfectly if burnt in Windows.
I also witnessed similar bugs on an Ubuntu laptop of a friend.
