[...that the track number is in BCD on the disk, yes, we know.]

[0]Now, there are plenty of makes of CD-ROM drives that return info to
[0]the host in BCD, and this is because most of the fields on the actual disk
[0]are in BCD.

[1]Yes, but SCSI requires the drive to return it as an integer value.
[1]Any drive returning BCD is violating the specs.

Agreed.  My point all along is that we should not incorporate any
change that allows for more than 99 DECIMAL tracks, even if there is
(A) media cut that way and (B) one drive that can cope with it.
Too many things will fall over.
