Joe, that is absolutely true. I was not considering the speed or caching
abilities of the drive itself. I was thinking more generically of an
approach that would work OK for both a sluggish floppy and a faster hard
disk without software changes. Additional accesses penalize floppies, but
that may not be an issue for Bob. --Patrick
