Here's what I have noticed with my ST277N (and pre-Kronos A1000 CLTD
controller, although not for much longer):   After a write, there's a second
or two before it flushes the buffer and closes the file which makes a little
noise and flashes the light.  A second or two after THAT, I always hear
a tiny noise and a very brief flash, which I always assumed was the drive
autoparking after a few seconds of non-use.

But about a week ago, for the first time, the drive started doing stuff
by itself when I was **not** accessing it.  Since then it has stopped. 
I'm begining to think this might be some sort of virus.  Gee, I hope it
isn't...

Anybody else out there getting unwanted hard disk accesses?
