I also run Disk >> Repairs at the same time. here is an excellent utility that one should use in conjuction with disk utility. it's called 'system optimizer 4.1' - http://www.mkd.cc/ basically, once a week you should run disk utility, then when thats done and all seems fine on your drives, run sys optimizer and let it do its thing. it takes maybe 10-20 minutes, but it actually keeps your system running nice a fast. i haven't had any kernel panic issues anymore, and the pre-binding of the apps loads a lot of my apps faster. great application that should be required on all mac osx hd! hak :: jungleDUB inna 2003 www.easeuprecordings.com
