The first write goes fine, I have rw permission on the device, I use /dev/hdc, all is fine. I can mount the CD, read it, etc. However - it was written with the -multi option so I can add things to it, since most of my backups are 50MB at a time. When I try to get the size (using a perl script) which does: cdrecord dev=/dev/hdc -msinfo I get permission denied. Even if I set cdrecord setuid (as a test, I don't run that way). Back to ide-scsi, the perl program allows me to have the best features of growisofs and some other usefulk features for backing up relatively small datasets on a single CD. Just a FYI - I assume there's a good reason why reading the unclosed filesystem size would compromise security.
