Diskeeper is an automatic disk defragmenter that features scheduling and a high level of configuration ability, and can defragment even critical system files. Fragmentation occurs during normal Windows operation, as files are broken up in pieces and saved on different parts of the hard disk. This increases the amount of time it takes to access single files, and bogs down system performance.

Hah... I've also experienced serious corruption of NTFS volumes after using Diskeeper's offline defrag feature. And I've seen it happen with multiple versions of Diskeeper. I'll never trust it again.

Love it - never a problem.

Works ok. In my opinion bloated and no major change from previous versions, not worth any paid upgrade. Product activation is another aggravation - no thanks.

2009 version is just slightly better than 2008, so i will stay with 2008. I don't think it is worth to do upgrade. But is nice program and i did not had any problems with it, so i give 4 rating.

Diskeeper 2008 Pro user since it was released last year, and now currently trying out the 2009 Pro version on XP. To cut a long story short: DK 2009 Pro is awesome. The defrag engine has been tweaked some more, and is blazing fast. Defrags all three drives at the same time, without bringing the system down to a crawl. One of the non-system drives had only 7% free space, but DK 2009 managed to defrag it fully without breaking into a sweat. Not many defraggers can do that. Finally, a welcome inclusion of file placement algorithms in the 2009 Pro edition. This is the best defragger I've used. Highly recommended!

If you get it to work correctly should be a fairly good utility definitely not the best of the best. On my computer I still have to figure out why boot-time defrag stops with an unexpected error 0xc0000043 and how to correct it. I 'm welcoming any help. I'm running DK pro premier 2009. Thanks.

This is not a product review, but rather a review on the company. Recently, Diskeeper has been accused of forcing their employees to either take part in Scientology training, or be laid off. Regardless if it's Scientology, Christianity, Buddhism, or any other belief, this is discrimination and is not acceptable from any corporation. http://www.google.com/ne...cientology&ie=UTF-8

For weya1b0: if still interesting in 0xC0000043 solution, make this steps: 1.Disable Antivirus self defense 2.Find key in regstry [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\KLIF] "Start"=dword:00000001 change to "Start"=dword:00000003 3. Set Diskeeper to Boot-time defrag 4. Restart PC 5. Boot-time started normaly, phase 3 iniatialised, defragmentation work. 6. After defrag, set registry back to "Start"=dword:00000001. 7.Restart PC, enable antivirus self defense.

Thanks to jahamaville for the heads up. This should be called the Scientology Defrag. No thanks, keep your religion out of your company and out of my HDD

I've used Diskeeper professional 2009 since its release last year, and it's one of the best performing and most trouble-free utilities I have on my system. It's unintrusive, doesn't conflict with any other application and simply does a fantastic job of keeping the drives tidy. Highly recommended.

They hit a home run with this 2010 version. The home version works great unless you need the pro version for a business. Integrates well with Windows 7. It actually reduced my boot-up time by almost a minute.

Bloated, overpriced, intrusive piece of junk.

Diskeeper is running a special for $10 off Diskeeper 2010 Professional edition for Memorial Day. With this release they are taking a proactive approach by preventing the fragmentation up front. Great product. http://bit.ly/ayd2e0

Reviewing Diskeeper 2010 Premier Pro v14.0.909.0 on Windows XP SP3 (32bit/x86) I've been a user of mstDefrag for the last 3-4 years and have also used O&O Professional, PerfectDisk, myDefrag, UltraDefrag, and Defraggler but I think this is the best. Advantages: 1. The automatic defrag and proactive defrag prevention actually work (unlike other programs that claim to do it) set it and forget it. 2. Ability to defrag Windows system files, boot files, and Hard Disk MFT. 3. Quite fast at a full manual defrag compared to others I have used. 4. Lots of options, features, and config settings. 5. Noticeable increase in system performance. Disadvantages: 1. Bloated GUI. 2. Memory usage on the Diskeeper Service (DkService.exe) [which facilitates the automatic defrag etc] is 52,000k+ regardless of whether program is running or not. The program itself (mmc.exe) takes around 16,000k when running. 3. The "Volume Health and Recommendations" are well off the mark, and overly sensitive. 4. Troublesome to activate. I am not an expert by any means, just thought I would share my thoughts.

The only thing more corrupt than the code that went into this thing is my hard drive after running it. I'll stick with mst Defrag. It's far cheaper, and it works great. And as far as I know, the author isn't a proselytizing religious nut.
