I have exactly your configuration (Amiga2000+A2090+ST251).

In the 3 months I've had this configuration I NEVER had any of the problems
you mentioned.  The ST251 will park the heads off the plates at power-down
so you don't even need to wait for the disk to spin down.  And note that I
develop and test on this machine, so I get visited by the guru all the time,
including in the middle of disk writes, and with file opened.  The only 
problem (!?) is that sometimes when I create a REALLY bad crash (fireworks on
he screen) the real-time clock gets screwed up (my fault of course), and I have
to run setclock.  All in all the machine has been pretty reliable.

I suspect that either you have an old version of hardisk.device or you have
hardware problems (it could be the system unit, the controller or the drive 
itself).
