Norton utilities is still available, and it will continue to be supported for OS X 10.3 Panther, but not for future versions of the Mac OS. SpeedDisk might be the best way to go if you could get a copy of Norton Utilities inexpensively, and you could resist installing the other components of NU on your hard drive. See: http://www.buy.com/retail/product.asp?sku=20360224&loc= I can't recommend Alsoft's Plus Optimizer because it hasn't been updated since 2001, it needs to boot into OS 9 to run, and from what I have heard from users, and from my own experience (it won't even attempt to defragment my hard drive running OS X), I worry that, while it is OS X-compatible that it isn't particularly OS X-savvy. That leaves: INTECH SPEED TOOLS http://www.intechusa.com/ TECHTOOL PRO http://www.micromat.com/tt_pro_4/tt_pro_4.html DRIVE 10 http://www.micromat.com/drive_10/drive_10_introduction.html I own and have used TechTool Pro, and it seems to work fine. I don't enough about the other two to make a recommendation one way or the other. Randy B.
