    "puts Drive Genius's defrag to SHAME"

    March 31, 2008  |   By knowmacpro

    Version: iDefrag 1.6.5

    Summary

    This review was originally posted on VersionTracker.com.
    I have been using iDefrag for years. These guys are on top of their game, for sure. The current Leopard version works great.
    Get this. Drive Genius 2.02 CANNOT defrag, unless you boot from the DVD! Who wants to do that???
    Buy, and enjoy the increased operation speed this utility DOES provide!

    "Demo - Not Really"

    Summary

    What a joke. You can't demo the defragmenter if your hard drive is over 100mb. Why in the world is this a "Demo". Waste of time if you looking for a demo before you shell out $30-40 bucks.

    Version: iDefrag 1.6.5

    Summary

    ...iDefrag lives on.
    This review was originally posted on VersionTracker.com.
    Just used it on 12" Powerbook G4, using the Full defragment settings. Not a single problem. If you frequently use very large media files, then I think defragmenting may be a necessity. For the rest of us, defragmenting/optimizing maybe 3 or four times a year is helpful. Diskwarrior is far more important for everyone, but iDefrag is a good supplemental maintenance tool. Interestingly, I think that DiskWarrior in OS9 days actually included an addtional application to defragment files (I forget what it is called).

    Version: iDefrag 1.6.5

    Summary

    This review was originally posted on VersionTracker.com.
    I have been using this since it came out and it is really good. Yes you can all pretend that the mac OS with it's little defrags at startup are enough. And they are, if you are just doing a bit of emailing and text docs, with the odd photo thrown in. If however you are moving big files in and out, which I am, iDefrag is survival toolkit. Along with Disk Warrior and Superduper. This trinity of tools has kept my rig running sweet and fast for a long time.

    I just defraged a Leopard HD from a Leopard HD and all went well. Started up on the drive and it was fine,

    Glad you are back boys! And sorry I was taking the P a while back, missed being able to defrag in Leopard.

    Cheers

    Version: iDefrag 1.6.3

    Summary

    This review was originally posted on VersionTracker.com.
    I have used this ever since it first came out and I am impressed by the work it has done for me on my hard drives. After it has finished with a full optimize you just know that the heads on your drive are working more easily. Performance is improved.

    What makes me laugh is the wording when they say. Leopard is not compatible with our software. Come on boys, just admit it. Your software is not compatible with Leopard.

    You will feel better for it.

    "One-trick pony really performs"

    June 7, 2007  |   By dvk1

    Version: iDefrag 1.6.1

    Summary

    This review was originally posted on VersionTracker.com.
    Most average users do not need this product but if you use very large files (>20MB) or have a disk pushing the limits of its capacity, then iDefrag is effective, seems safe, and is about as fast as you get.

    I did a Compact run on a G4 portable (using iDefrag Lite) with 60GB of data (100GB disk) and it took a couple of hours or less. That made it easy to re-partition with iPartition to add a Leopard beta.

    I also used a licensed version on a full defrag of 80GB of data on an Intel MacBook Pro (160GB disk). That took nearly six hours but the work involved is significantly greater than for Compact. The screen dimmed normally based on Preferences on my Firewire boot disk (thanks, SuperDuper!) so it is safe to run this overnight on any machine. Make sure you sit a portable on a flat clean surface or even on a large heatsink. The disk gets a workout and older models do not have heat sensing. iDefrag will monitor your hard disk if it can, and will pause if it gets hot.

    Other comments below, and stuff on the Coriolis web site, make clear when you might need to use this product and the fact that many or most people do not. However, if you need it, this does it. Great product.

    "Very good tool"

    April 7, 2007  |   By ecdltf

    Version: iDefrag 1.6.1

    Summary

    This review was originally posted on VersionTracker.com.
    This tool is working very well. For the people who are complaining about the slowness: try to disable the various security options and disable the class based file rearrangement. You won't find any tool that defragments faster.
    Another great fact is, that additional to the defragmentation of the contents you can also rebuild your metadata (extents catalogue, b-tree ...). Some weeks ago DiskWarrior reported a problem it couldn't repair. I've run the rebuild function of idefrag successfully, and once again DiskWarrior and - voilà - DiskWarrior rebuilt my directory without problems.
    Since then I run idefrag as the first directory repair tool and afterward the good old Diskwarrior - only as a doublecheck.

    Bought it. Still defragging 11 hours later. User beware! This may be the best thing since sliced bread, but by the time you get to eat it it may be moldy.
    Also, find the anti-piracy tone to be unusually threatening.

    "Great product, very happy"

    Version: iDefrag 1.5.8

    Summary

    This review was originally posted on VersionTracker.com.
    I bought this program and after testing it out I think it's great. Just to clarify: if almost all of your files less than 20MB (documents, photos, mp3s) then you do not need this program. OSX 10.3 and up will defragment small files automatically, and that will probably be good enough. If however you are like me and you have lots of files over 20MB, and especially if your disk is more than 50% full, then this program is a godsend. In short, it is the perfect utility.

    I will assume you are familiar with disk fragmentation and suspect that you need it. If you're unsure, the free demo of iDefrag will let you examine your disk.

    Here are a few of iDefrag's features that I liked the most:
    - $30 USD - cheap! I did not want to pay $100.
    - does every type of defragmenting thing imaginable
    - comes with a program to make a boot cd
    - can rebuild B-Trees (like DiskWarrior!)

    The program includes an optimizer to move applications and file system structures to the start of the disk. The standard defragmenting algorithm (compact) is fast, and there is a "quick" algorithm which just defragments files but not free space. The quick algorithm can be run on the disk you boot from. To run the other algorithms on your main hard drive you need to boot from cd. You can run any algorithm on an external hard drive without rebooting.

    The interface is extremely polished and includes a number of nice touches, such as box showing the file associated with each particular part of the disk. The program verifies writes and can be interrupted safely (I tested that on my boot volume). iDefrag respects the "hot area" of the disk and can also rebuild B-Trees, which speeds up the finder along with everything else.

    My only complaint about the program is that it can not ignore files on damaged parts of the disk. To be fair, other defrag utilities will not do this either, but it's annoying to encounter bad blocks one at a time and have to reboot each time to delete the offending file. OS X needs a surface scanner.

    I highly recommend iDefrag to anyone who works with larger files regularly, and especially to people with external hard drives. It's a great defragmenting program. For best results I suggest the following strategy:

    - the first time you run the program do a "Full Defrag"
    - after working on large files a lot use "Quick Defrag"
    - to free up big blocks of free space use "Compact"
    - if Finder is slow defrag metadata only and rebuild all the B-Trees
    - running "Optimize" over and over is a waste of time

    I hope this review has been helpful. I tested iDefrag 1.5.8 on a 1GHz iBook G4 with 768mb of ram running OS X 10.3.9. It makes a Tiger boot cd so it should obviously be Tiger compatible. Be sure to check out the demo if you're interested. I think this is a great program.
