Probably not, but I always do a full backup before a defrag (and would even
with a program that claims to be power-failure proof).  Of course, I have a
tape backup, so such a backup is no big deal for me....  You will notice, 
though, that DOG is twice as fast as PC Tools compress even though both are
very careful to keep the FATs updated.

}Which of the three support >32M partitions?

No idea.  I'm only using 32M partitions, so I never bothered to check.  New
versions of PC Tools and Optune no doubt support huge partitions.
