• Updated version no longer works. Only simulates defrag

  diskman2020August 4, 2017

  Pros

  Used to work. No longer does.

  Cons

  Broken, as of late July 2017. The manufacturer apparently no longer provides support for this product (even though they only just released the update! Go figure...), and there's no signs of life from any of their "contact" e-mails. The product seems to be dead.

  Summary

  It used to work quite well, when I first bought it a couple of years ago, but after getting notification of a new version two weeks ago, it died. I downloaded and installed the update, only to find that it no longer works. It now only **simulates** the defrag, but does not actually do anything. I tried to contact them SIX TIMES at the Disktrix support e-mail address, and their commercial e-mail address too, but they don't even bother acknowledging my mails. DO NOT BUY THIS PRODUCT! IT does not work any more, and there is no longer any support for it. Did they go out of business maybe? Pity: it used to be good.

• a way to damage the file system

  looki901November 23, 2013

  Pros

  the overall idea of the app is very good, it indeed can optimize the system if "all" the most used files can be found in a sequential stripe of data

  Cons

  spite the fact of the app having a good idea, it cant execute very well, there seems to be many bugs in the app, one of them are, some times it become stuck in some file that is currently in use by the OS, and, then it enter in an infinite loop, until the app freeze and you have to close and open again... also, there seems that the function to defrag individual files seems to be buggy, one time I tried it and my files got damaged, so it not works always, and the MFT defrag, and boot defrag, some times does not seems to work well

  Summary

  I hope some day it get fixed and become a better defragger!

• the cnet editor needs to be fired

  stewievaderNovember 19, 2012

  Pros

  this is a very powerfull and great tool the interface is well designed,giving you an exact view of your hard-drive(unless your unskilled at computers like this editor) it can do stuff NO OTHER DEFRAGMENTER CAN. (resize/defrag/move mft and pagefile) ever since norton abandoned their defragmenter way back,there has never been a program that will let you defragment or move the nfts files.

  Cons

  the downside being you have to have a decent knowledge of computers in general to understand this program....which the cnet reviewer doesnt have

  Summary

  very powerfull,lets you modify files no other defragmenter can requires moderate computer skills

• Excellent Product!

  Sawdust94May 30, 2012

  Pros

  Takes a bit of getting use to but it does an excellent job, top notch. I love the fact you can see the exact disk layout. Its has excellent features. It is way up there in the top 3 Defrag programs without doubt!

  Cons

  None that I know and I have tested everything on it.

  Summary

  Take the time to get use to it and it will reward you.

• Very good Disk Optmzr & Defragmntr (Win Vista Ultimate)

  AlphaOhmsNovember 2, 2011

  Pros

  Fast defragmenter. Easy to use GUI, which has an original "disk" layout look of the drive. Click on a colored block on the GUI disk, and it shows the file and defrag option of the cluster - Very, very nice! Has the option to manually place your most accessed files to the edge of the disk, in theory the outside of drum spins faster, hence the file is manipulated for execution and/or read/write access faster. I noticed a definite improvement in speed and file access, when this program gave me the option to place my operating system files and game files that I use on this gaming rig to far outside portions of the disk drum. WOW! My games really fly now! No more game lags! And my boot up is twice as fast (original boot speed = approx. 2min., new boot speed = approx. 45secs.) No other program I know of allows me to place files on the disk drum where the read/write heads access the files faster. UltimateDefrag is the only program I know of. I thank the developers for their hard work.

  Cons

  I have not found any bugs with this program. So far, it does what is says. Read the manual closely. I also didn't notice any blocks or clusters that were introduced after defragmentation, and my disk didn't get fouled up. I will say that some of those small clusters I saw were the MFT and the boot loader. They are perfectly fine on my system after defragmentation.

  Summary

  The reason why people get errors or corrupted disks after using a professional deframenter, such as UltimateDefrag, is because they forget to run a CHKDSK (check disk for errors and repair) before running a disk defragmenter. Everyone should run a CHKDSK and fix any bad blocks or corrupted clusters before defragmenting their hard drive. This is a normal procedure I have used before defragging a hard drive. If you skip that, anyone with any defrag product will have serious or lost data issues. So, don't forget to run CHKDSK before defragging with any utility. Also note that even new hard drives can come with bad blocks too - I've had this experience.<br /><br /><span class='notifyMsg'> Updated </span>on Nov 17, 2011<p/>To the person that has replied to my review: I'm not a sponsored reviewer. Those green clusters that show up as used (occupied) is normal before the disk is analyzed. In other words, when you launch the program (UltimateDefrag), you will see clusters that show up as occupied without knowing what is in them. Any defrag utility will not know what occupies the clusters until you analyze the disk. After you analyze the disk before defragging it, UltimateDefrag will see what is in them with the correct Start Cluster and End Cluster value. I see no problem with their product, and as a power user for my gaming rig, this is the best program I've ever encountered for a defrag utility!<br /><br /><span class='notifyMsg'> Updated </span>on Nov 19, 2011<p/>To B-2Admirer, I'm not a sponsored reviewer. Make sure you download the latest version of UltimateDefrag from DiskTrix website. I still don't see any cluster problem after analysis and defrag jobs, and their program has never failed to analyze my hard drives. Maybe you could provide more information about your system and a step by step procedure that would reproduce the bug. Developers can't fix a problem if they can't reproduce the bug.<br /><br /><span class='notifyMsg'> Updated </span>on Nov 20, 2011<p/>The DiskTrix Song DiskTrix... DiskTrix... I've got a Disk Trick for you Oh won't you please watch my Disk Tricks A wonderful neat thing to do It will make your pee cee so happy Your hard drive will spin true blue DiskTrix... DiskTrix... Oh won't you please watch my Disk Tricks Monitor lights will be dancing, Dancing to the DiskTrix tune All the files are blooming They love the DiskTrix groove.

• Not recommended and potentially dangerous.

  B-2AdmirerOctober 22, 2011

  Pros

  None known.

  Cons

  Bugs and developers' attitude (seee below).

  Summary

  I have tried many defragmenters looking for the most suitable for my needs and at first really liked this one. However, almost immediatelly I have noticed that it fails to assign some clusters to the files they belong to (shows them as occupied, but doesn't see what occupies them). Naturally, it cannot move such clusters which botches the whole defragmentation process. In order to make sure it's a bug and not a problem with my disk I tried using it on a newly formatted disk with a few fragmented files thrown in, and guess what? The unassigned (green) clusters, which weren't present before defragmentation, appeared after, which means the program fouls up the disk it defragments (although, in fairness I have to say that in my case it did not lead to the loss of data, only made subsequent defragmentation pointless). Of course, I reported the bug to the support and after a rather long delay was contacted by the lead developer. The conversations with him dragged on for nearly 4 months and all the time he promised to fix the bug later while constantly making excuses as to why he haven't done it already. My last two messages to him were completely ignored, as were my messages to the support with requests to investigate. The bottom line is, giving their unwillingness to fix even critical bugs, using this program is highly not recommended.<br /><br /><span class='notifyMsg'> Updated </span>on Nov 16, 2011<p/>As to the next reviewer's (evidently sponsored) assumtions about disks not being checked prior to defragmentation or bad blocks on new drives, one can hardly react to them with anything but scorn. I've already stated that the bug was admitted by the lead developer, even though it has never been fixed and for whatever it's worth to anyone, I'll also add that I did check my disk with CHKDSK prior to defragmentation and I always do a full surface test on the newly purchased disks in order to ensure they contain no bad sectors.<br /><br /><span class='notifyMsg'> Updated </span>on Nov 19, 2011<p/>Regarding yet another series of tall tales from the next reviewer who denies being sponsored but behaves more and more as if he was, I consider it's totally self-explanatory that the bug I encountered is manifested in unassigned but occupied clusters present AFTER the disk analysis. The program, of course, needs to analyse the disk to determine which file a cluster belongs to, trouble is the analyses sometimes fails.

• A few good ideas poorly executed

  GP_dadAugust 13, 2011

  Pros

  It's paid for two versions of the product and it offers an interesting display (circular, like a disk) and several defragging options.

  Cons

  Buggy and unstable on Window 7 Ultimate. Some defrag algorithms are flawed--files are moved unnecessarily; in another case, it kept moving the same file back and forth. Apparently unsupported--never received a response to any emailed questions.

  Summary

  Have not found an damaged file as a result of Disktrix's problems so far but it's worrisome. Defragging is like surgery on your drive, and in both cases a botched event is painful and expensive. I'm going back to Contig.exe; it's free and stable.

• UltimateDefrag is one of the most versatile defraggers

  bobengelMay 29, 2011

  Pros

  Many options are available in addition to standard defragmenting. Novices can easily use the automated processes but experts and tweakers will want to explore some of the more esoteric features to fine-tune their hard drive file placement.

  Cons

  Unless a hard drive is badly defragmented, the overall speed benefits resulting from basic defragging may not be very noticeable.

  Summary

  UltimateDefrag has an excellent users manual in .pdf format. It should be reviewed before attempting to incorporate some of the optional features in the program. The display is very colorful and reveals exactly how and where files are being placed based on the initial analysis. However, watching the hard drive file mapping during the processes can be a bit mesmerizing. Fortunately, the program can be left to operate in the background

• After some experimentation, the BEST defragger ever!

  knightmarez28May 23, 2011

  Pros

  You can see a massive difference even after just one thorough defrag, everything loads up much faster and I've used more than 10 different defragging utilities both free editions and paid for and by far this is the best yet!

  Cons

  It can be tricky and confusing to use, on occasion boot-time defrag failed until I figured out how to get it working the way I needed it to.

  Summary

  Honestly, even just novice users can learn how to use this program relatively easily. Unless you're tweaking out your system for maximum performance, just select auto defragmentation and let it go. Experiment with it a little or ask around even. But personally, I will not be using another defragging utility other than Ultimate Defrag, thanks for putting out a great product!
