What do the bits in VCBAtrb field mean? IV-177 sez that:
	0-4 something about inconsistencies
	6   set if volume is busy
	7   set if volume is locked by hardware
	15  set if volume is looked by software

When I checked out my HDs and floppy I found that bit 6 was always
set and bit 5 was set only on my HDs. Bit 9 was set only on my
floppy.

The reason I want to know this stuff is because I'm trying to write
a substitute for SFDialog and I need to know if I can eject a volume.

Does anyone know how to detect when a volume is mounted or dismounted
without watching disk insert events or scanning the volume indexes?
Does anyone know where SFDialog gets the volume's SICNs? How do you
know if your talking to a floppy or an HD? Is it a good idea to use
the mod date to see if a volume has changed? If Finder checks the
mod date why doesn't it do it more often?

Thanx in advance.
