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.

@xXAkumuXx In your response below you cite Apple KB HT1375:
"If your disks are almost full, and you often modify or create large files"
Then you said:
"If you are working with large files, defragging helps."
Just to be clear...large files and "defragging" are mutually exclusive. If you're running out of space, get a larger drive or clear room on the drive. If the cause of "fragmentation" is due to the lack of space, then this utility is indeed a placebo, since it does not fix the problem but instead it provides a false, tempoarary sense of relief.
The more users understand it's a matter of disc space, the more users will understand this utility is simply a waste of money.
I'm sure the developer's marketing department will disagree. After all, it's the marketing department's job to convince you that you NEED their product.

well except for the update this time so i am getting it apart.
i have a question to all of you: i checked this several times out: if you run a full defag and afterwards run DW graph the directories have NO items out of order. does this mean idefrag does the same job DW does? or what is the explanation?
thanks if someone knows

iDefrag does recognize *some* problems and will (can?) suggest running a repair utility before optimizing.

Upgrade price is OK also the upgrade process was very easy.
HINT: You dont need to defrag all files every time - iDefrag, thats unique to all other defrag tools, let you defrag single files from the fragment list shown after the analyse process. Mostly only some but always same files (aperture files, some db files) are high fragmented and gets defraged by an simple click on defrag file within seconds - minute.
iDefrag is great - even for non highend users.
Last but not least: Nerver run such tools without an Volume check (and repair if needed) on your mac.

These are: VMWARE + PARALLELS hd image files, big caches which getting worse after high fragmentation and all other big files with often added / changed content = fragmentation.

I knock it down one star on ease of use as I would like to be able to select multiple files in the file pane.

I only use this software several times a year for annual drive maintenance upkeep alongside other utilities such as Onyx, DiskWarrior, and simply fiddling around in Terminal (a lot of maintenance can be done in Terminal).
I don't understand all the bickering. This is most certainly not a useless app, or "snake oil", as one member put it. If you don't need it, that's fine. If you do, you know personally what it can do for you, otherwise you wouldn't have bought it in the first place. No need to fight to the death trying to prove your point.
Anyway, great and reliable app. Have been using it for years. Thanks devs.

The ability to reboot into iDefrag's special mode allowing you to defragment the boot drive is nice and a speedy alternative to using a separate drive with installed OS, et al. That said, it's speed depends on overall fragmentation of your drive and also the size of the drive being defragmented. I don't use my entire 500GB HDD as my boot drive, I partition it into a 125GB boot drive (OS, applications, user folder, et al) and save the rest of the drive for a separate partition for other uses (alternate OS installs, etc); this makes the time needed to defragment my drive quite quick (relatively, it generally take 3-4h and I usually do it overnight, when I do it).
Overall, it's a nice tool in the toolbox; I also have DiskWarrior to help in diagnosing system issues and other tools (Onyx is my go to first tool, after Disk Utility). It is nice to have also when dealing with other Mac users issues, as their drives often are so fragmented that they are often luck to have a single 5GB or so continuous space available on their HDDs. So it is for everyone, no; is it for the user who knows what to use it for, when and why, maybe if you need it.

I'm having the updating issue as well. I ended up downloading it manually from my account again. No biggie, but it's something that should be addressed.

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.
