iDefrag helps defragment and optimize your disk for improved performance. Features include:
- Supports HFS and HFS+ (Mac OS Extended).
- Supports case sensitive and journaled filesystems.
- Supports adaptive hot file clustering ("Hot Zone").
- Four powerful defragmentation algorithms:
- Compact data, moving all free space to one place.
- Optimize filesystem metadata.
- On-line defragmentation.
- Defragment whilst your disk is mounted.
- Advanced programmable optimization.
- Rearrange your disk the way you want.
- B-Tree metadata file
What's New
Version 2.2.0:
- Fixed an issue with temperature monitoring on some newer disks.
- Fixed a bug in the B-Tree code that would mean B-Trees could end up being less compact than they should be. This was most noticeable if you had the B-Tree rebuilding option enabled.
- Fixed a few minor memory leaks.
- Added support for creating a recovery disk with iDefrag which is suitable for machines that no longer come with installation media.
- Fixed an issue that started appearing with the Mountain Lion previews.
- Fixed a couple of rare crashers.
- Fixed an issue that might have meant iDefrag didn't find free regions as efficiently as it should have done.
- Refactored restart feature slightly to improve behaviour on machines that have unexpected incompatibilities.
- Fixed some other minor bugs.
- Fixed a problem on 10.6 (and possibly 10.5) where data could be corrupted if a machine slept after defragmenting when using iDefrag’s exclusive restart feature.
- Fixed auto-updates.

Defragging has been rock solid and noticeably improves disk performance on my system partition (~6500 fragmented files). Not worth defragging too often but once every few months seems the right balance, especially if you work with files >20MB regularly...

You don't have to pay for this upgrade, just click on developers website, log in to your account and d'load it from there, just did it.

Paid twice? As in version 1, then upgrade to Ver2? If so, there is no additional charge for this update. If you paid twice for the same version, then you need to contact the developer about combining your multiple customer records into 1 --- and arrange a refund.

I first reviewed it when I was using a G% PPC with 4 internal hard drives with multiple partitions each. Now I'm using it with a Mac Mini Server with 2 internal drives and 3 external ones. OS X 10.7.4
While trying to watch a video that I have on one of my external drives, the video would freeze and become jittery and unresponsive. I checked the drive's fragmentation and although it was low fragmentation was present. I ran iDefrag and immediately after finishing the defragmentation process the videos were watchable without any issues.
This has been the same experience I've had before, although usually I work with audio files.
The down side is that the full defragmentation process can take too long. This time it took over 30 hours. To be fair, IIRC the drive is 1 or 3 TB in size, and I was using the computer to work on other things while iDefrag was working.

You can select any (not opened, not blocked by system) file in the drag list and use the defrag file icon to defrag that files you want.
Then you get your most fragged file defragged within minutes, not hours. Of course some full defrag may be usefull to, but not as often you use manual file defrag - maybe 1 / year or 2 / year of full defrag are enough. But as always: The HD should have enough freespace , >= 20% or it will get defragged very fast again in usage.

I do a full defrag of all my disks roughly 3 times a year.

It took about nearly 3 hours. After that a popup-Window told me, the first new start would take a little bit longer, and it did. But now, after 3 new starts, the system seems to me ro be faster. Absolutely faster is the start of all my apps, unbelievably but true!
Great, thanks for it!!!

That this can happen says a lot about the integrity (or lack of integrity) of the MacUpdate ranking system.
Is it the developer who is pulling up our profile in MacUpdate and hitting -1 on all our reviews? Is it a troll? Does it matter?
What matters is this placebo, snake oil "utility" is being exposed as a waste of money.
A fool and his or her money are soon parted.

My rational guess is that your lame comments/reviews on this application gets voted down by actual happy users of the application, real people who, like me, has a need for this app, since harddisk drives actually DO GET FRAGMENTED, and OSX does not by itself defragment large files.
You fail understand that more space on your drive has nothing to do with this matter. You misinterpret the description, purpose and usefulness of the app. In my view, you are almost too dumb to exist.

"real people who, like me, has a need for this app"
Based on your grammar, I'm guessing you're from Ukraine (where this placebo application is developed).
I'm sure watching the pretty boxes moving around the screen can get quite addicting. Too bad the pretty boxes have little relevance to the physical layout of the data on the drive, or how your hard drive caches, reads and writes the data.

I think Apple's KB article HT1375 addresses your perceived need quite effectively:

I really could care less what your application does or how it works. What's important is how Coriolis Systems is stealing from unsuspecting Mac users who fall for the hype.
So Bumbleb, while your personal insults only show you're growing frustrated, one can safely assume you're coming to terms with the fact that you wasted your money and are only starting to relize it, or that you are the vendor desperately trying to preserve the "need" for your utility. Much like a crack dealer has to ensure his customers continue to use his product.

There's criticizing an app, and there's absolutely trolling it to death. Seems to me like you're venting out all the day's frustration onto this one app. I'll take your advice, for the time being, though.

But the problem is this!! Many users fill up their hard disks. If you do this, fragmentation can be a REAL problem no matter what type of filesystem you use.
In this case, a third party defragger may really speed up your hard disks.
In http://support.apple.com/kb/HT1375, Apple stated:
"If your disks are almost full, and you often modify or create large files (such as editing video, but see the Tip below if you use iMovie and Mac OS X 10.3), there's a chance the disks could be fragmented. In this case, you might benefit from defragmentation, which can be performed with some third-party disk utilities. "
But in my view, the BEST way to defrag is to back up your hard disk, erase it and then restore the hard disk. This will ALWAYS provide the best results. Best of all it is FREE and often the FASTEST way to defrag.

What I see is, someone who purchased iDefrag back in OS X Tiger can still run it (with all bug fixes) on Snow Leopard. That is something unheard of... Only Alsoft (makers of Disk Warrior) does a similar thing.
If you want pure 64bit application with improved algorithm and _additional, new features_, you pay $14. If you don't? Well, the "unfriendly" developer is decent enough to maintain 1.x version.

Because of this, I will no longer be using iDefrag. I'd rather have a fragmented disk and keep my old backups.

You can find out what the maximum operating temperature for your drive is either by looking up the serial number (in Disk Utility or System Profiler) and sending it in to us, or by looking on the hard drive manufacturer's website.
Alternatively, and obviously at your own risk, you can disable the thermal monitoring feature in Preferences.

Micromat clearly tells it in several places. You can't trust to a partition or a dedicated drive to run single software to run another advanced software.
We have a Beta version out that does and we hope to release it properly soon.
