For what it's worth, Computer Shopper magasine, several months ago (forget
which issue and I'm not at home to look it up...sorry), feature an article
reviewing disk de-fragger's.  It compared Norton's SD, Paul Mace Utilities,
and several others (did *not* include DOG as I recall).  They had problems
with Norton's SD and recommened against using it until Norton brings out a
revision which successfully fixes the problems.  They gave top marks to
Mace.  It was by far the slowest but also by far gave the best performance
and seemed the most robust (I forget the details of the testing procedures).

They cautioned against using a de-fragger with any TSR's or installed device
drivers which could potentially interfere with with the de-fragger...and this
was not limited to disk cache's and the like but also to other seemingly
innocuous programs which could alter timing considerations or cause missed
interrupts and the like (...I don't really know what I'm talking about there,
that's just how I remember it).  This was, in fact, related to the problems
with SD and most de-fraggers warn you about it anyway (some refuse to op-
erate if they detect any).

If anyone likes, I can easily look up the issue and provide further details.

Cheers...JW
