Sounds like a long visit from the disk validator.  This can happen when the
system crashes somehow in the middle of a disk operation, even if the crash
occurs at a relatively safe time, like when no disk activity is actually 
taking place.  The disk's bitmap gets marked invalid, some operations take
place, and before the disk get marked valid again, the crash takes place.
Next time you start up the disk's handler, it validates the bitmap, which on
a nearly full 20Meg hard drive certainly could take some time.  The SupraMount
command is probably why this happened before you could see the disk; on a
HD that get's mounted via BindDrivers, the disk usually shows up as soon as
the system comes up, even though the validator may run for some time.

How is the Supra Drive?  A friend asked me about a problem he's having with it
in combination with a ComSpec memory card; maybe you or someone else out there
has some ideas.  He's got an Amiga with a 68010 (running DeciGel), the 
2 meg ComSpec, and the Supra.  When the ComSpec and Supra are used together,
the machine gurus in WorkBench.  Used separately, they work OK.  And he hasn't
been able to make them crash together from CLI.  I'm not at all familiar
with the Supra Drive, but that SupraMount command is the first thing that
makes me suspicious.

We have lots of cow problems here in PA, so I can sympathize.  Can't keep the
suckers out of lab or the computer rooms....
