Well my understanding is this: HFS volumes have APPLE_HFS as their partition
name. ProDOS volumes have the volume name as their partition name. So the
rub is having a driver which will consider partitions with names other than
APPLE_HFS as possible disk volumes. I use Apple's formatter on everything so
I don't know what anyone else's driver supports.

There's a similar problem with disks formatted with HD SC setup 7.3.5 and
Drive Setup on IIgses. Instead of putting the driver in a partition named
APPLE_DRIVER, they put it in a partition named APPLE_DRIVER43, which denotes
a SCSI Manager 4.3 savvy driver. When the finder comes up on a IIgs, it knows
to ignore partitions named APPLE_DRIVER, but the 43 on the end makes it think
that the driver partition is a volume. It of course is in no format that the
OS can understand so the finder complains about it.

:     Yep, that works really nicely (I didn't realize just how neat 
: it was until I got to try it). The only thing is AppleTalk is really
: quite slow, but it's a nicer option than using floppy disks (lately
: I've been annoyed by floppies since they'll read fine in one drive
: but not another) or even a null-modem connection.

Yep it's pretty dad gum spiffy. Especially on ethernet, where the speed is 
tolerable. I've had to copy 100 plus megabytes over localtalk in one shot
before, and we're talking hours.
