Question copying CD to HD


I am trying to use dd to copy a cd to HD to make an iso file. I have done this many times before with both data and audio cd's. Here is the result this time:

# dd if=/dev/cdrom of=mycd.iso
dd: reading `/dev/cdrom': Input/output error
0+0 records in
0+0 records out

I tried googling it and found similar problems but I did not find anyone who got experienced 0+0 records in/out... it was also some value.

Any ideas?

Thank you very much for helping!

Is it one of those audio CDs that have evil copy-protection?

You might need to become root to read
a raw-device (which is what dd does).

Check the permissions.

Cheers,

Thanks for the quick reponses, I did try it as root (same result). How can I find out if it has evil copy protection? I've never even heard of it.

Thanks

Nope, the 0,0,0 doesn't work... I can't even read from the CD...

#cat /dev/cdrom
cat: /dev/cdrom: Input/output error

I assume this is unusual for audio CD's... any ideas?
