Wonderful idea. Although I believe the "pause if running" option
allows the client to be paused while an arbitrary program is
running and it can be set to the Norton Speed Disk program.
I would love to see an option to stop writing to disk on running
defrag. I do video editing on my system and have 150 Gigs of disk
on raid drives for most of my stuff, plus one 4 Gig SCSI drive that
I use only for windoze swap and distributed net buffers/checkpoint/
etc. Obviously, my defrags take forever (I let them run overnight),
and when I was using windows defrag, the client would stop the
Since then, I've gone to using Norton, and just skip defragging
the "G" drive, or defrag it manually after stopping the client.
