Anyone else experiencing/experienced this problem? Any help/info is greatly appreciated. I have a set of cds that contain MP3 files that I am trying to access. The cds have been burned on multiple brands of cd (Sony, Maxell, Imation), with multiple burners (HP 7200, Plextor 12/10/32). Regular audio cds work fine. After tinkering with mount_cd9660, I found that the title of the disk is read properly and there is a directory created in the /Volumes for the cd, and automount attempts to mount the disk putting the following in /var/log/system.log: Sep 29 01:04:13 Computer /sbin/autodiskmount: DiskVolume_mount_foreign: unrecognized return code from foreignMountDevice: -4 Sep 29 01:04:13 Computer /sbin/autodiskmount: disk1s0 udf no no MP320020221 [not mounted] Also after messing with mount_cd9660 I found that I could successfully mount the disk on the directory in the /Volumes directory that (I assume) autodiskmount is creating. And that the contents work properly. So this rules out it being a problem with the hardware, the media, firmware, etc. It pretty much has to be a problem with autodiskmount recognizing the disk as a "udf" disk rather than a "iso9660" disk, is there a way around this, so that autodiskmount will pickup the cd properly? thanks in advance...
