Anyone know of a Defrag utility that can handle a hard drive with a capacity of 640GB's and works fast and well?I have used DiskKeeper for some time, but discovered that it is not compatible with drive volumes above a little over 500GB.I have a Raid0 Array with two 320GB drives. The Defragmentation utility sees this as a single harddrive with the sum total capacity of these drives and some utilities cannot handle this volume. Fortunately, the default MS provisions can, but it would be nice to have something a bit faster and more automatic. When I used DiskKeeper, I defraged every night automatically with the "set it and forget it" provisions while asleep, but it is not good for this capacity.Thanks:RTH

So far, Disktrix - Ultimate Defrag and Raxco - Perfect Disk, my two favorite, handle my 640GB (Raid-5 array) drive fine.
