just want to share some enthusiasm about diskwarrior. formerly, with windows, i couldnt live without norton utilities. as there are no more norton utilities for macs, well, i tried diskwarrior. as a kind of insurance policy. nothing more important than a smoothly running OS. even though mac OS has no registry and all of that: diskwarrior in a first run found quite some open holes in my directory. and provides an excellent defragmentation. well, and did I mention that i like diskwarrior?
