Unable to mount CD. Possibly my CD-ROM just dead?
 
Hi all.
That's what i get when trying to mount a CD:
Code:

mount /mnt/cdrom
mount: No medium found

Output of 'dmesg' showing a long list of errors like these:
Code:

hdd: tray open
end_request: I/O error, dev hdd, sector 24
Buffer I/O error on device hdd, logical block 6
hdd: tray open
end_request: I/O error, dev hdd, sector 28
Buffer I/O error on device hdd, logical block 7
hdd: tray open
end_request: I/O error, dev hdd, sector 24
Buffer I/O error on device hdd, logical block 6
hdd: tray open
end_request: I/O error, dev hdd, sector 28
Buffer I/O error on device hdd, logical block 7

I'm on Yoper Linux, kernel 2.6.8.1-3.
My fstab entry for this drive is:
Code:

/dev/cdrom1    /mnt/cdrom      auto      ro,exec,noauto,users  0      0
It worked fine untill today. How can i figure out if this is hardware problem or something just misconfigured in my system?

Well, you could go the easy route and just stick a bootable CD into your drive and reboot.

I seem to have the same problem as z-vet

Whenever I attempt to mount either of my two cd drives with a cd in them, i get the message

mount: No medium found
Please check that the disk is entered correctly.

My output of dmesg also shows a long list of errors similar to z-vet:

cdrom: open failed.
cdrom: open failed.
cdrom: open failed.
cdrom: open failed.
hdd: tray open
end_request: I/O error, dev hdd, sector 64
hdd: tray open
end_request: I/O error, dev hdd, sector 8388600
hdd: tray open
end_request: I/O error, dev hdd, sector 8387576
hdd: tray open
end_request: I/O error, dev hdd, sector 8387352
hdd: tray open

My fstab entries for these are:

/dev/cdrom /mnt/cdrom udf,iso9660 noauto,users,dev,ro 0 0
/dev/cdrom1 /mnt/cdrom1 udf,iso9660 noauto,users,dev,ro 0 0

I am on Mepis 3.3, kernel 2.6.10.

Here is where I start to differ from z-vet

First, let's establish that i have two cd drives; cd drive A and cd drive B

1-I just installed Mepis 3.3 yesterday from cd drive A and have successfully booted from a boot cd multiple times from cd drive A
2-I could not successfully boot from drive B
3-BUT prior to installing Mepis 3.3 I could never get cd drive A to mount, but never investigated why because i could get by using cd drive B
4-Prior to installing Mepis 3.3 cd drive B would mount without any problems

To put it short: I can boot from CD drive A, so it works, but it won't mount
CD drive B won't mount, either, but it won't boot, so it's possible it is just dead

Also, please be patient with me, I am just some girl who has a friend who loves linux, so I don't really know that much, but I can follow good directions. I won't be surprised at all if this is all a result of some small, stupid mistake.

BTW, said friend doesn't know what to do about it

I am just wondering if I should just give up on these old cd drives, or if I need to change some settings? I have tried to include all the info that is pertinent.

My CD-Rom was dead, i just checked it on another machine, so i bought a new one...
adorablesquire, i had an exactly same output of dmesg about my drive, so i think yours is finished his career too...
