mount_cd9660 : Invalid argument ..

[daemonfowl]

Hi !

Yet another OS-based legacy issue ..

Some of those data dvds which I burnt on mac bahave strangely :
when I try mounting them , I receive such an error message :

mount_cd9660: /dev/cd0a on /home/bifrost/cdrom: Invalid argument

this dvd was/is accessible on mac/windows .. I wonder what kind of problem it is .. burning tool ? data arrangement ?
it contains almost 4 g of misc data .. is this something I should avoid ?

When you report a problem, @daemonfowl, please follow the helpful guide in the "perfect newbie" thread that we've pointed you to several times. Ask yourself, "have I posted enough information that someone can recreate my problem or point to an error I have made?"

This problem report is missing critical information. What was the command that was used? Does the exact same command work with other discs? Was this command executed as root or as user? Does the directory /home/bifrost/cdrom exist? What are its access controls?

If you slow down before posting, and think of what questions we might ask before submitting your problem reports ... you might get useful responses.

Personally, I have never used "cd0a" -- because there is no "a" partition. I use "cd0c" as "c" is the reserved partition for the entire device. Whether this has any bearing on your problem... I have no idea.

What does disklabel(8) state? ie.

# disklabel cd0

Post the output.

@Jgimmi , sorry again .. well I agree with the rightness of every line you typed .. my report was short because I can still mount devices & thanks to

The likes of this dvd are but legacy-cases burnt on mac using quickburn or native burning tool .. etc

Ah. They are UDF. Not CD9660. Use mount or mount_udf.
