Kevin,

Actually, when in the course of our talks with Capitol Video I asked them what
their chief aggravations were in simulating CD-I titles, one of their biggest
complaints was that OS-9/UNIX could not actaully determine the PHYSICAL sectors
that were barfing in the CD-I image. The SCSI controller remapped all the bad
sectors out, and made the drive seem,once again, logically intact. Interesting
.... and somewhat of a future problem for multimedia moguls simulating their
applications off of hard drives.

I guess the biggest problem (although I really am NOT sure) is that, when
reading a realtime file with interleaved audio/video, the heads on the SCSI
drive actually reseek to find that remmapped sector, causing a hiccup, I guess.

Paul
