MACT3CH  This is in response to MACNERD1984, JDUB800, MACLODGE, and anyone else who is about to defragment their drive.

Keep in mind I don't particularly care for drive genius over any other utility. I prefer Disk Warrior for some things and TechTool for only one thing, drive scans (everything else is useless in this product . However from what you guys posted it sounds like you caused your problems by applying a "fix" that was not appropriate. If you attempt to defragment a drive that has file system errors or inconsistency then what do you think is going to happen? If you don't know what your doing then learn how stuff works before you throw things at it.

btw - In most cases the HFS file system doesn't require defragmentation unless you are using extremely large files. This file system corrupts easily from what I've observed working with it professionally over the last 4 years. So again your attention should be the integrity of the file system and not wither or not it's fragmented. Let windows users worry about fragments. We've got bigger issues.

ps - Also learn to recognize when your drive is failing before you run a bunch of useless stuff like software repairs. You might be making things worse. This also includes finding issues with you RAM by taking notice of corrupting drives. Find the cause and then the solution. Again just because it has a Fix button doesn't mean you should push it. It means think first, understand the issue, and then apply the correct repair to the problem.
