dkp said:Neither of those will defrag your disk. They do directory optimization. iDefrag does true defrag. You need to be able to boot from other than your normal boot disk to use it.
I downloaded iDefrag 1.6.1 (the latest version I think) from VersionTracker.
UPDATE
iDefrag is bundled with a special CD creator program that allow you to make a bootable CD or DVD with iDefrag on it. I bought the package and ran it on my Feb 2006 iMac (the first time since I bought it). My HD is not that full - only about 150 GB of the 500 GB total are in use. But it still took many hours to defrag - I started it at about 6 PM last night and it was about half done at midnight so I let it run overnight.
But in the end it was well worth it. Everything runs noticeably faster - from boot up to app launch.
