Writing CDs

reddwarf2956 · #1 19th March 2004, 03:38 PM

I have CD-R which I used to burn Fedora on CDs (several times). This drive read the CDs fine. One a seperate machine, a Ppro with a 52X CD drive installed, the CDs do not work.

What can I do to figure out how to get Fedora and other burned CDs to work on this machine with the 52X? Is it something with the drive speed? What about the standard differences that maybe at fault?

What speed did you burn the disks at? It's been my experiance that the higher the burn speed, the lower the chances that the disk will be readable on other machines. I can't burn CD's on my desktop machine much over 2X and have them be readable with my laptop.
About the only time you'll run into a format standards problem is with CD-RW's burned with Windows CD-RW software.

Also you might want to try different media (ie TDK rather than Memorex or something (although I have found both of those to be rather reliable)).

Will do, for now I am on hold with this problem until the lost desktop links and files are sovled. I will test these and reply later on this thanks both so far.

I got a book on FC1 which has 2 CDs. I place the first one in the CD drive and the same thing happened. Right now it boots RH9 without thinking of booting FC1.
I wonder why?

Another thing, when I mout the drive using
"mount /dev/cdrom"
I get a error:

UDF-fs: No VRS found

Why? I am thinking that the /etc/fstab file maybe incorrect. I am I wrong, what else could it be? Maybe, this is why it is not working right.

O.K. I'll get obvious question out of the way...
You do have your computer's BIOS set to boot from CDROM right?

VRS?... It's not a DVD drive is it? The fstab entry for a CDROM drive should look something like this:
/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0

Did you turn off plug and play in the bios?
Did your check the md5sums on the downloaded ISO's?
Did you burn at the slowest possible speed on the more fault tolerant CDRW's?
What was the make and model of the burner?

Yes, it is set to boot from CDROM. It must be something with this VRS error.

Yes , the line is as stated and in /etc/fstab

Counterspy,

I did not check the PnP in bios, but I did check the MD5. Because of the new CDs I did not do the burn again.

During the reboot while checking the bios I saw this

Boot from ATAPI CD-ROM
System Type-(00)
GRUB Loading stage 2

I have never need to mess with the PnP stuff, so what things need to be done with all of the options? If I turn it off, will I need to do anything to keep the other PnP things working correctly?

I was doing some looking for howto's for a Jaz drive which is on the machine, but not set up and thought about the fact that the CDROM and SCSI sorfware are simular. Is there a way to check for conflics? Maybe this is causing my problem?

It's just possible that your jaz drive is being confused for a cdrom. Take a look through the hardware browser and see what device your cdrom is (example: /dev/scd0)and see what device your jaz drive is. /dev/cdrom is a symbolic link to the actual device, so using your file manager, check and see what device /dev/cdrom points to.

reddwarf2956 · #12 25th March 2004, 03:31 PM

The machine is command line only. Do you know the statement I need to run?

Lindy · #13 26th March 2004, 06:57 PM

ls -l /dev | grep cdrom should tell you what the symlink cdrom points to. Use vi or the editor of your choice to take a dash through /var/log/messages and see what your cdrom, and jaz drives are.

After doing some things, I have come to think that the problem has been with the CD drive itself or the computer BIOS. It is a Ppro machine so I will not worry about this any more. I did a few hardware swaps, to decide this so I know it is not to be solved by software. But using a floppy I can install Fedora just fine.

So I will tag this one as resolved.
