"My Samsung is in love with O&O"

December 14, 2012  |  By Ibracadabra009

2012-12-14 08:01:29  |  By Ibracadabra009

 |  Version: O&O Defrag Professional 16.0.151

Pros

I tried PerfectDisk 12.5, Diskeeper 2012 and I always went back to O&O. My system is way faster with this program, just use for start Space and then Complete/NAME and you PC will be in form :D

Cons

I don't know what's better defrag in background or screensaver defrag, i can't find that in help. But for me that's not Cons.

"Very Confusing Options/Settings!"

November 20, 2012  |  By scottls59901

2012-11-20 15:44:53  |  By scottls59901

 |  Version: O&O Defrag Professional Edition 15.8.801

Pros

A good price, and Lots of Options!

Cons

-Trying to figure out which Settings & defrag Options, is Very Confusing!?-
Using the Default's...- My system is slower!

- I wish they had a Forum, where you could ask other Users about Best Performance settings...!?

Summary

My system was faster with free Defraggler, but No MFT boot defrag.

O&O would probably be faster, If I could just set it up properly...!?

"Version 16 Is Buggy"

September 22, 2012  |  By -Surrey-

2012-09-22 17:43:42  |  By -Surrey-

 |  Version: O&O Defrag Professional Edition 15.8.801

Pros

New History section in version 16 comparing defrags before and after.

Cons

Version 16 is buggy.

Summary

Been using version 15. Installed and used version 16 awhile and it is buggy.

Version 15 used to automatically analyze disks when program started. Now in v16 you have to manually click Analyze button to analyze each disk, before and after a defrag.

When you run a Stealth defrag, after it finishes, it states, for example, 14% degree of fragmentation. But then after you click the Analyze button, after it finishes analyzing the disk, it states 85% degree.

Shutdown function after job completion no longer works.

External hard drives clusters appear in grey instead of colors (internal hard drives clusters appear correctly in colors)

Defragmentation speed is the same as v15 despite developer's claim of a 40% improvement.

Reverted back to version 15.

"Best out there but serious drawbacks"

July 21, 2012  |  By jackandcicely

2012-07-21 11:56:12  |  By jackandcicely

 |  Version: O&O Defrag Professional Edition 15.8.801

Pros

Windows 7 version sweet with perceived improvements in speed and effectiveness over Microsoft defrag.

Cons

Under Windows XP Professional (on PC and laptop)similar improvements not noticeable. On power down, both computers hang waiting for OODTRAY to finish and frequently power off is only achieved by forcing the program to finish, or sometimes holding the power off button in for 5 seconds. This is just unacceptable. Uninstalling is exceptionally difficult with neither the Control Panel nor the manufacturers Uninstall working, aftermarket uninstallers also do not remove it effectively. Manual removal seems to be the only way. Fatal flaw under XP.

Summary

Excellent under Windows 7.

You'd have to be mad to use it under XP

"Cannot uninstall"

June 10, 2012  |  By S_T_AN

2012-06-10 00:38:34  |  By S_T_AN

 |  Version: O&O Defrag Professional Edition 15.5.323

Pros

Easy to download in the first place!

Cons

Very slow in comparison to some other top quality progs. Not the best interface by any means. Cannot uninstall easily. Just a pain overall.

Summary

It is all to messy and difficult to sort out - even the uninstall side of things is made virtually impossible to achieve (and the only reason I say "virtually impossible" is that I intend to find a way, but obviously not with the help of O&O!)

"Works great and at 1/2 the price of some others"

September 26, 2011  |  By bdoggaustin

2011-09-26 04:04:42  |  By bdoggaustin

 |  Version: O&O Defrag Professional Edition 14.5.543

Pros

Fast and effective (I can definitely tell a difference after it has run)

Cons

If I had to choose one, it would be that there are not very many custom options (ie defragging methods, not that I would know what to choose anyway)

What's new in version 20
Version 20: O&O DiskStat integrated. O&O DiskStat provides you with an overall view of just how your hard disk is being used. It lets you track down those files and folders that are taking up too much space on your hard disk, and causing your computer to slow down. You can sort by category, file type, view them in Explorer and export them as a table. A further major function to speed up your systems. Improved optimization of SSDs: File systems on SSDs fragment heavily. As well as regular TRIM optimizations, O&O Defrag 19 also improves the structure of the SSD file systems by optimizing the most fragmented files to increase performance and life expectancy.
