This one is really boggling me.

For the past couple of days I have sucessfully been using my two different CDROM drives. I have an ATAPI DVD drive & a LITE-ON 48x burner. I have been using both to copy files, etc.

After a reboot this morning I get this error from fstab.

'updatting fstab. /mnt/cdrom1 no such file or directory'

Now my burner-drive wont work. My fstab looks fine--like I never touched it--but the drive just isn't recognized. Does anyone have any suggestions? Could a program installation have messed with it? I don't think I did anything...

Suggestion...

If there's no.. /mnt/cdrom1 directory..


MAKE ONE!

Uhm... now I feel like a retard. I know I didn't erase it, but I just made a new one. Let me give this another shot.

Ok, that actually wasn't the problem. I mean, no, there wasn't a /mnt/cdrom1 directory but here is the exact error. (I made sure to copy it down correctly)

cannot stat /dev/cdrom1 no such file or directory [FAILED]

There may not be such a device file. You can try
ln -l /dev/cdrom1
To see if it exists. If your cd is in the second IDE channel try
mount -t iso9660 /dev/hdc /dev/cdrom1
if you have a cd burner it may be /dev/scd0
When you find the correct device file you can set up a symlink to it eg
ln -s /dev/hdc /dev/cdrom
Hope this gives you some idears.

Yeah it turned out to be located at /dev/scd0. I've got it fixed.

That does seem really odd though because for the first two days of this installation it was /dev/cdrom1 and then somehow it switched on me. Does Linux do that often? It is a LITE-ON burner so I dont know if it should be at the other location afterall... should I be worried about my other /dev moving on me?

/dev/cdrom1 is a soft link that points to a device in the /dev directory.

In order to know where Linux assigns each device, use the dmesg command.
For example:

Sweet thanks. I'll remember that command next time I 'lose' something. I am really wondering why it would change locations like that mid-day. Two days in a row it was found at /dev/cdrom1 and then it just seemed to move to /dev/scd0...

Did you add a new device or perform an upgrade ?

To find out where /dev/cdrom1 is pointing to, type:

I didn't do any kind of hardware upgrade or software upgrade (that I know of). It just seems to have moved. I got it working now by repointing the line in fstab to /dev/scd0.

I would like to recompile my kernel. Is that going to be considered an 'upgrade' and cause me to have to repoint things again?

Compiling your kernel should not move things. Never has for me and I have done it many times. Adding or changeing your disk drives around could through. Anyway glad you are sorted now.
