and the second usually reports SMART status.
The first is a mountpoint or volume, the second a device.
right
Volume's
don't do SMART.
then how come some do?
No volumes do SMART, only devices. That is SMART only ever applies to
the device.
It may /appear/ that a volume is a drive, but this is perceptual.
Firewire and USB drives will never do SMART.
I recall in the OS9 days it was possible to have a machine without the Apple
driver installed.
There are drivers and there are drivers.
There are drivers on the device store as partitions, and there are
kexts that are drivers in the OS.
The former is no longer necessary in OS X.
Often the machine partially worked but reported all manner of
weird errors.
This seems really weird that a few machines would indeed report a smart status
if the / was used instead of disk0....
Is this the only volume on said device? In which case the OS will
substitute these.
