[QUOTE="bobtomay, post: 921686, member: 24160"] Pertaining to defragging your Mac, it just simply is not needed for the vast majority of users. [URL="http://support.apple.com/kb/HT1375?viewlocale=en_US"]Here[/URL] is the Apple kb article about it and there are more technical articles that can be found with a little googling. As an example, I quite literally download and install 150-200 apps a year. Over 90% of them are also uninstalled in a very short time. Not to mention downloading music and video that consequently get moved to the server. We both know what happens to a Windows system volume with this sort of practice. The last time I installed iDefrag just to check it out, my system was less than 2% fragmented - and this was 2 years after a clean install. This wouldn't even be a reason to defrag a Windows volume. Now I also use other best practices. For example, I never allow any system volume less than 35%+ free space. (Even though I only recommend 20-25% and less than 15% is def bad practice.) There may be reasons to defrag as noted in the Apple article - i.e. you're running a volume close to being full coupled with installing and removing large files on an ongoing basis. As to the fsck error, that is another matter. I would suggest booting from your OS X install disk and using Disk Utility to run a repair. [/QUOTE]
