PostPosted: Thu Jun 01, 2006 8:10 pm    Post subject: cdrom - "no media found" Reply with quote

I am runing a Compaq 6370 with linux dual booted with Win-XP. I have 2 cdrom drives. Both work fine in XP but one of them gets a "no medium found" message when I try to mount it running linux.
I have googled till I just can't anymore.
cdrom hdc /media/cdrom1 is a cyberdrv cw078d and is the drive that fails.
cdrom hdd /media/cdrom0 is hl-dt-st dvd-rom gdr8161b and works fine.
/etc/fstab is the same for both cdrom0 and cdrom1, 2 lines only cdrom0 is different than cdrom1.
/dev/hdd and /dev/hdc do exist as Block device.
I use kde to eject cdrom1 and it does the eject.
I use kde to eject cdrom0 and it says "failed /dev/hdc"

Anyone have any ideas???

Thanks Ray

just to make sure : 'mount' may fail if there is no cd-rom in the cdrom station, so if you've been trying to mount an empty cdrom station, try with a cd in it first.

according to your fstab, you have the 2 cdrom stations attached to the secundary IDE controller. So one should be master, the other one slave.
Do both of them show up during POST (Power-on Self Test : all that info about drives and ram and pci-devices and irq's that shows on the screen when your machine starts up) ? As Master and Slave ?

Last time i bouth a cdrom drive (about 7 years ago Smile ) cdroms were sold with a jumper set to 'slave'. Don't know if that's still the case but you might want to check the jumpers on both cd-drives. hdc should be set to 'master' and hdd should be 'slave' -- or the other way around : the one with the jumper on 'master will become hdc, etc
Some people advise also to have the master attached at the end of the IDE cable, and the slave in the middle.

Hi Koen,
Thanks for the reply. Sounds like you know a lot about Linux and cdroms. I would like to pick your brain a little.

I do know to have a cd in the drive before I do the mount so that is OK.

I have had this system with the 2 cdroms for 4 years and have been using the drives with no problems under Win XP. I think the drives are OK.

I just made a discovery, If I bootup Linux and put a Debian Linux distribution cd in hdc: and mount and open it, I can read it fine.

I unmount the debian cd and mount a win xp cd in hdc: and I get a message "no medium found"and I also cannot do an eject, I get "eject /dev/hdc failed".

I manually remove the win xp cd and put the debian cd back in and try to mount it. I get "no medium found". Strange !!!

Well it gets stranger. If I put the debian cd in hdd: (the other drive) it works well. I eject that cd and put in win xp cd in hdd: and mount and open it I can read the data on the cd. I then unmount and insert debian cd and mount and I can read it fine. I can switch back and forth between
win xp cd and debian linux cd as many times as I like and all is OK.

It seems that hdc: is the only drive with a problem.

If I reboot and try a debian linux cd in dc: it works fine.
If I then try a win xp cd it renders hdc: useless for linux cds and win xp cds until reboot.

Sorry for so much blah blah.

Anyway here is a snipet of my dmesg file:

Sure, there's probably nothing wrong with the drives. Still, they may be misconfigured, and Linux is more demanding at that in order to maintain a certain level of stability and performance.
After all, you say it yourself :
[quote]It seems that hdc: is the only drive with a problem. [/quote], and that happens to be the master, but probably has a default 'slave' configuration.

check those jumpers. Either it will solve the problem, or you can eliminate one (very) probable cause and take it from there.

Hi Koen,
I checked the jumpers and found both drives jumpered for CS (chip select). I guess that is OK but am not sure. Have to go for now, another project. I'll be back in the morning.

Buy the way .... Thanks again.

that's CS for Cable Select, it means that the order of the drives is determined by their position on the cable. It should work, but doesn't always. personally I like to set the jumpers ( MA for master, SL for slave) so that I know what I'm dealing with.
guess it wouldn't hurt to give that a try.
An other thing to try is switch the position of the disks while they are jumpered for CS. The outcome of that might give us a clue.

Hi Folks,
Koen, Embarassed I didn't know what CS meant so I googled and found as usual (old-out of date-incorrect-too much garbage) which said CS was chip select in terms of master slave relationships. I stand informed by Koen that it is cable select. Well I learned something anyway. By the way I am just learning Linux so please don't be too hard on me.

I swapped the drives leaving them CS. The problem follows the drive, now hdd: fails.

I changed to hdc: Master, hdd: Slave. hdd: still fails.

I swapped back. now hdc: fails.

I swapped Master jumper to Slave and Slave to Master hdc: fails.

I put everything back to original and hdc: fails.

At least no hard done.

I tried some things and found that any product cds I have around like the Debian cds and Sierra LandDesigner all work fine in both drives. I then tried a CD-R written on Win_XP and it worked fine in both drives.
I then tried a NEW BLANK CD-R in drive hdc: and got:
"mount: wrong FS type, bad option, bad superblock on /dev/hdc"
I was able to eject and try a debian cd with no problems.
I then tried the NEW BLANK in hdd: and got:
"no medium found".
I was able to eject and try a debian cd with no problems.

I then tried a CD-RW in hdd: (which is a dvd/rom) and it works fine.
Then I tried a CD-RW in hdc: (which is a cd/rw) and got:
"mount: no medium found"

Now I get the "no medium found" for a mount of any cd in hdc: until I reboot.

All I proved and I guess it is good is that the position of the drives using CS or Master slave make no difference. A new blank cd from the store does not work in hdc: or hdd: unless I write it with win xp (then it is ok) and a CD-RW does not Work in hdc: but does work fine in hdd:.

If I boot Win XP I can use the drives normally.

This cannot be a hardware problem because if I reboot Linux I can use hdc: as long as I don't put a CD-RW or a new blank CD-R in hdc:.
Somehow linux is remembering this and needs a reset of some kind.

Thanks,
Ray

Ok, this is beginning to look like there may be a problem in mounting the hdc drive.

After you get the "no medium found" error on hdc, what happens if you try [code:1]umount -l /dev/hdc[/code:1] ?


How (with which commands) do you mount your cd drives ?

I've done some googling on the subject and there seems to be tons of people who have (or had) this problem, but no definite answers anywhere. Some sources suggest a bug in kernel 2.4 and the related drivers. What kernel are you using ? (uname -r)

excellent feedback.
It is possible you're mounting with the wrong filesystem type.
iso9660 is common for production cd's and cd's written "Disk-At-Once" or "Track-At-Once". CD-ROM and especially CD-RW may be created with Packet Writing and then mounting with [b] -t udf [/b] might work.
This seems more or less consistent with your posts saying you can read Debian setup media OK, but fail on CD'-RW wriiten under Windows XP. The buit-in "copy files to CD" feature in Windows XP uses Packet Writing.

So, you could try to mount the CD's that produce the error with
[code:1]mount /dev/hdc -t udf -r /media/cdrom1 [/code:1]
you will need the full command, the abbreviated form will read the wrong filesystem type (iso9660) from fstab.

If this works, it would explain the "wrong fs type" error. The 'no medium' error might refer to the fact that the cd wasn't "closed" after writing the data and can therefore not be read if the software that reads it expects an "EndOfFile" or "EndOfStream" before it starts rendering the data - but here I'm just guessing Smile

Again, I've found post about udf-failures in kernel 2.4, and developers discussing patches in kernel 2.5 (de development kernel that is released as 2.6). So you still may need to dist-upgrade, as you're running 2.4.27-...

Hi Koen,
I tried what you suggested (mount /dev/hdc -t udf -r /media/cdrom1 ) and got the same results.

I think I found the problem. I started all over creating CDs and trying them in 2 PCs.
One pc is running WIN XP only and uses a collection of CDROM programs that came pre-installed.
These are the roxio directcd programs. The CDROM drive is a CD-R/CD-RW DVD. The program Doc. leads me
to believe I can create a data cd with CDCREATER but it will not it always uses DIRECTCD. The rub
is that DIRECTCD only uses UDF. When the data cd is created and you try to eject the cd you get
a message asking if you want to leave the cd as is so you can continue to use it as a drive letter
access cd or close it as UDF or close it so it can be read in ALL or ANY CDs. Well of course I
choose the later. When I make this choice the program does format work to do its thing and then ejects
the CD and messages that it can now be read by any CD.
Now to the other PC, its a dual boot WIN XP and LINUX. It has as you know 2 CDROMS, hdc: CDROM1
CD-R/CD-RW and hdd: CDROM0 CD-R DVD. I can read any distribution CD in both drives. I can read any
CD I created on this PC because RECORD NOW is the program I use and it does not use UDF it uses
Joliet which is really iso9660. So now I finaly get back to the real problem.
CDs created with DIRECTCD (UDF but closed in some way that WIN XP can use in any CDROM) can be
read in both drives when running WIN XP but only in hdd: CDROM0 when mounted in LINUX. I guess I can
live with this for now. I can read the CDs from DIRECTCD in the hdd: CDROM and move the data.

For your info and anyone else lurking it is good to note that in the heat of battle I forgot
that you can't just mount a new blank CD. You need some kind of software to handle new blank CDs
and to burn them.

Thank you very much for ALL the help. I am off to my next bucket of snakes, cdrecord mkisofs
or whatever LINUX uses.

glad you got a situation you can live with, even if it's not a complete sollution.
So, at least it head something to do with the filesystem type though it does still puzzle me a bit - e.g. that "close it so it can be read in ALL or ANY CD" renders your CD unreadable in the CD-reader (/writer) you have as hdc.

FYI, Joliet isn't exactly iso9660. It's a microsoft extension to iso9660, i.e. iso 9660 + some added microsoft features such as support for long file names, very long directory paths, filenamls with 16bit characters (Unicode) in stead of 8bit characters (ascii), etc. But they're compatible.

If you want to create cd's under Linux, there are probably some desktop tools with GUI's that make it real easy, but as you mention mkisofs, you may be interested in command line interface and see what goes on behind the windows. Here's something I came across :
[url]http://www-128.ibm.com/developerworks/linux/library/l-cdburn.html[/url]
maybe a little outdated (2003 !) but it 'll give you an idea.


oh, and maybe the trouble your having with these Windows-created unreadable cd's got solved in kernel 2.6 or the modules that come with it. Smile

If I don't do this I can't read it in hdd:either because it is pure udc without the added magic of which I do not know.

That is exactly what I meant to say only you said it better.

I installed the xcdroast package a few minutes ago and it works real well.
It is a GUI cd burner that is very well done.
I created a data cd on a CD-R blank cd. I then read it in both my drives and it worked fine.
