picard Documentation/Options/CD Lookup
On Windows, Picard has a pulldown menu listing the various CD drives it has found. Pull down the menu and select the drive you want.
as per Aaron Coopers mailing list post located here
You have to make sure you have the correct rdisk# entered in the preferences.
Open up Terminal and type 'cd /dev/rdisk' and hit Tab twice to see all the rdisks. You're looking for one that has several "tracks" - like /dev/rdisk1a .... rdisk 1f or something similar.
Enter this /dev/rdisk# into preferences and it should work.
Linux, other platforms
On Linux and other platforms, the CD Lookup option is an empty text field. Type in the name of the path to the CD Rom drive. In most cases, this is /dev/cdrom (for the first drive) and /dev/cdrom1 (for a second drive).
However, depending on your system, many different paths could be appropriate (source: source code for "eject" command): a prefix of /dev/ followed by something, or a prefix of /media/, /mnt/, /dev/cdroms/, /dev/cdroms/...0, /dev/rdsk/, or /dev/dsk/.
One way to test whether a path is the right one is:
- Put a CD into the appropriate drive
- At a Terminal, type the command eject followed by the path you are testing (e.g. eject /dev/cdrom)
- The CD should eject.
- If it does, the path is what you want.
- If it doesn't, then try other paths.
