Product Description:
Advanced Mac OS X disk defragmentation and optimization. Supports the very latest features of HFS+, including journaling, case sensitive filenames and adaptive hot file clustering (which means it won't mess-up the Hot Zone).
What's new in this version:
We strongly recommend that all users update to this release ASAP to benefit from the bug fixes.
- Fixed a problem that was causing the GUI to hang when iDefrag was unable to read the name of a folder (typically whilst trying to report an overlapping file error during a scan of the extent information).
- Fixed a serious problem relating to files with individual extents of more than 4GB in length. Whilst relocating such extents, iDefrag would copy the wrong amount of data, resulting in corruption. (This problem only affects the off-line defrag algorithms, Compact, Optimize and Metadata, although the Metadata algorithm is very unlikely to trigger the bug.)
Operating System Requirements:
This product is designed to run on the following operating systems:
- Mac OS X 10.3
Additional Requirements:
- Mac OS X 10.3 or higher

I have been using this program since it was released. It has never damaged anything and has always improved the performance of my drives.
Apple say that defrag and optimazation is not needed in OSX and that is true ,IF all you do is check you mail each day and surf the net.
If however you do a lot of video work, moving big files about every day then it is indispensable. Not that you need to use it every day, it just depends how much data comes and goes through your drive. Another time would be after a system update. File all over the drive after that.
Also if you need to repartition a drive without losing data then you need to move files to one side of the drive first. This is the only program that does it reliably.
To answer the last poster no it does not do the same as Superduper will to an erased drive. It will make a perfect clone of the drive you are copying with all it's faults or graces.
After using Macs for 15 years everyday there are three programs that I can't live without and are a must.
1. DiskWarrior 2. Superduper 3. iDefrag. And this is not necessarily in the order of importance, it just depends which one saved my ass most recently! Lordy is that the trinity!

I am not (yet) an iDefrag user, and my knowledge/understanding of defraging/optimization is nil, so I well understand if my question is off base.
SuperDuper allows me the option to erase a drive/volume prior to copying the backup. Doesn’t the erasing accomplish the same thing?
I know iDefrag has more bells and whistles (some are of no benefit to me) and it may defrag faster, but as I use/schedule SuperDuper while I sleep, I see no advantage there.
So for folks such as me, why use iDefrag?
No offense is intended to the developers, I just don’t understand.

Another thing to consider: iDefrag "optimization" really doesn't optimize that well. iDefrag "optimizes" by cramming all your system files together, app files together, data files together, which is a step in the right direction but not true optimization. True optimization involves putting all your Photoshop files together, all your iTunes files together, all your Final Cut files together, so that each application has the files it needs located nearby on the drive. iDefrag just doesn't do that. "Copy/format/copy back" processes do.
