iDefrag Usage TipA warning about iDefrag - Version: 1.7.1, 10/11/2009 11:27AM PST

Something you might want to consider: iDefrag will not run on a Mac that is running from a cd or dvd. In order for iDefrag to run it must be able to write its licensing key to a specific location in the copy of the Mac OS you booted on. It can't write to a cd or dvd and consequently it can't run when you boot from a typical cd, dvd, TechTool eDrive, etc. Consequently, the only way to iDefrag your normal boot disk is to create an additional bootable partition and start from that or create a "special" boot cd using Coriolis' CDMaker app. That's probably why CDMaker exists at all. That's a lot of garbage to deal with when the real problem is Coriolis System's excessively restrictive licensing scheme, which can prevent legitmately licensed users from performing legimate activities permitted by Coriolis' own license agreement.

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.

iDefrag ReviewReally Good Solid Utility! - Version: 1.6.9, 7/30/2009 05:47AM PST

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!

iDefrag CommentaryiDefrag vs. SuperDuper - Version: 1.6.8, 6/8/2009 05:54AM PST

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.

I paid for this application in a painful way, not just the price of a copy. I left a follow up comment of my detailed experience with it. I guess the the maker and/or versiontracker didn't like my totally rational comment and concerns, so they deleted them. Part of what I said was leaving a warning that was on their very web site but in my own words. I personally would like to know if an application has the potential to do damage to my computer. So I was doing a favor for other users, that's what comments and reviews are for. I guess we'll just have to do google searches from now on the get the truth about an application.

I have been using iDefrag for a couple of years now and have had nothing but good results. It will take quite some time to do its job, but that is to be expected for all that it does. I have used it many times and have complete confidence with this application. Just don't expect iDefrag to do its work in a matter of minutes. Start it, let it run all night long and don't get impatient.

Tech support is also good the one time I needed it.

I bought this a long time ago. I did a full defrag on my Master while booted in the slave. A month later my brand new Master HD fried and took my Slave drive with it. I had a year old external HD so you know the rest of that story.

So I'm sure this app didn't do the damage, but now I'm sorta afraid of it now. They keep fixing issues, so that means it's still beta to me.

When it's a final product, I might try it again, but I didn't notice any speed improvements like the old Norton utilities defrag used to do years ago, and it didn't fully defrag, like putting ALL the colors where they go, but mostly it did. It was just sorta taking out the free space and compacting the drive.

Even if an app does damage, the maker will never fess up to it. There is one application I trust, SuperDuper, because it's an Awesome finished stable bootable cloning application. Just using that actually defrags, then you clone back to the master drive and there you have it.

I'm not shooting iDefrag down, it just scares the hell out of me, and always has. I'm not sure if they have a detailed PDF manual that explains in easy terms on what the different operations do and how to use them, but I'll go look for it.

iDefrag ReviewAwesome program. - Version: 1.6.6, 11/26/2008 07:21PM PST

This is a great utility program. I did benchmarks before and after defragmenting, and the stopwatch noted some significant differences in speed on program startups, though two (out of 12) programs were a touch (about 2 sec, max) slower. Straightforward to use, effective, and easy. This is a regular part of my Mac utility cycle, and I even use it with my iPod classic.

I would skip the boot disc creator, however, and go with a flash drive with OS X installed, along with a few utilities. Faster and easier that way...

iDefrag ReviewDemo is Useless - Version: 1.6.6, 10/29/2008 07:05AM PST

The demo will only work on drives that are not larger than 100MB. Who still has a drive that small? All of my drives exceed 200GB. This proves that this product hasn't been updated for a long time. When's the last time anyone had a sub-GB hard drive????

Dont bother with this out-of-date program.
