No, when you install Diskeeper it replaces the built-in utility.
With Windows XP if any programs (even those running in the background) or the screensaver interrupts the defrag, it will restart/hang. In Vista, the defrag is designed to defrag at a certain schedule in low priorty in the background. In order to defrag and use the PC at the same time you need to use an automatic defragmenter like Diskeeper which runs in the background in invisitasking mode and defrags silently without conflicting with other programs.
Probably (1)file system errors (can be fixed with chkdsk/f) (2)insufficient free space for a defrag (do diskcleanup with ccleaner and get atleast 15% free space) (3)viruses or malware (scan as needed) (4)Locked or in-use system files such as paging file or MFT. (get Diskeeper and run a normal defrag followed by a boot-time defrag). ---------- Another user said: It can due to many reasons, lack of free space or program interrupting (run itin Safe Mode). If this doesnt help, try a third party trial version. Some work faster and more efficiently than the built in.
The Diskeeper Defragmenter does, indeed, seem to play havoc with the inbuilt Windows Defragmenter. After removing the Diskeeper software, I managed to reinstall the Windows one by using the information I found on a computer forum. For more information, see the Related Link. (1) It's never a good idea to run 2 defragmenters, since they may conflict with one another, and cause problems by locking up files for exclusive use. Another problem is that one might undo the work of the other since newer versions have more advanced algorithms for defragging and file sequencing. (2) The windows XP defragger is a very basic version of an old Diskeeper edition from many years ago. It was licensed by Microsoft. When you install a new version of Diskeeper, it only disables the XP defragger, it does not uninstall it. There is absolutely no point in having both the advanced (Diskeeper) as well the basic (XP defragger) versions of the software running on the same machine. Also see pt (1). If you had problems with the in-built XP defragger after uninstalling Diskeeper, it is most likely due to an MMC error and probably related to XP Service Pack 3. I am a long time Diskeeper user, and have never had trouble with the XP defragger even after uninstalling Diskeeper (or any other software for that matter).
Many people believe that your computer will work more efficiently if you defrag it regularly.
An anti-spyware program like Superantispyware, an antivirus like Avira or AVG, and regular defragmentation using either Window's built in defrag tool or Auslogics Disk Defrag etc.
It would'nt take forever but yes, normally the bigger your hard drive is, the longer it takes to defrag. It also depends on how bad the hard drive is in need of the defrag.
Usually not, The best Defrag program to use is the one the came Pre Installed in windows its located under Start, All Programs, Accessories, Tools - Or System Tools Defrag. What defrag does is put similar files together in order kinda like how a library puts books on a shelf, That way they can find them easier defrag is virtually the same.
Defrag
If you are running XP, while using the built in tool, make sure that no other program runs to interrupt its task,otherwise it may hang or restart. If you are running Windows Vista, its designed to defrag on its own and doesnt show a graphic or fragmentation visuals. Its however very slow and runs in low priority in the background. To be able to use the PC normally without conflicting with the defragmenter, you need to install a third party program like Diskeeper which can be run on automatic mode. It defrags silently even as you work.
To defragment a PST file, you can use the built-in Compact feature in Microsoft Outlook. First, close Outlook and navigate to the "File" tab, then select "Account Settings" and choose "Data Files." After selecting the PST file you want to defrag, click on "Settings" and then "Compact Now." This process will reorganize the data within the PST file, reducing its size and improving performance.
defrag/Defragment
I believe you are recommended to defrag your computer at least once a year but to be safe i usually run one every 2 months or so. I personally recommend you use a program called defraggler which does a good job at defragging.
