There were no messages in the files generated by syslogd(8) relating to the CD-ROM,
except the first time I tried to use SCSI hostadapter emulation, and it wasn't working, I
got plenty of hdb: driver not present. Now that the hostadapter emulation works, I think
that's irrelevant. :)

No, the progress bar is blank. I occasionally get a - or two and I got a ! on one track
on this particular disc. Other discs give me a continuous line of - (dashes) for every
track, with the occasional + or !. Another disc I have been trying to rip (where I
noticed the problem) has a blank progress bar for some tracks and all dashes for other
tracks, with the occasional ! or + thrown in.

I think you're right. For a typical disc, ripping a track which is 4:13.59 long. The
progress bar for this track when paranoia is enabled displays all - (dashes).

Which is about 0.4x.
