Right, which is why I thought the problem is with file systems rather than the drive. > Also, the majority of data DVDs are in UDF format, so make sure that you > can mount UDF files. I should be able to. As I said, I'm running 5-STABLE, which has mount_udf. > See if you can increase the verbosity of the mount at all. yggdrasil# mount_udf -v /dev/acd1 /cdrom1 mount_udf: /dev/acd1: Device busy yggdrasil# mount_udf -v /dev/acd1 /cdrom1 mount_udf: /dev/acd1: Input/output error It doesn't seem so, unfortunately. Are there tricks to get more verbosity? When I first put the disc in the access light flashes on and off for a while, and I get the 'Device busy' error during this time. After a while the access light just stays on and I get the I/O error. (With a CD or movie DVD, the access light will flash and then turn off until something is mounted/played.) -David -- "What's the good of having mastery over cosmic balance and knowing the secrets of fate if you can't blow something up?" -Terry Pratchett
