Re: WinXp Defrag starts automatically

Robert,

Disk defragmentation and auto-layout
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/xpehelp/html/xehowdisablingdiskdefragmentation.asp

BTW, that article was originally written for XP-Embedded. However, the
"EnableAutoLayout" registry setting very much applies to Windows XP Home and
Professional. Personally, I would not disable this feature, as it runs
during the idle time and does not affect my work anyway.

Description about this feature, as shown in Tweak UI screen:

"Optimize hard disk when idle" check box allows Windows to rearrange
files on the hard disk when the computer is not in use to improve
performance.

If you don't want this feature, you can disable the auto-optimization
feature using Tweak UI. Download/Install Tweak UI and run it. Look in the
General section, and uncheck "Optimize hard disk when idle".

TweakUI download URLs:

TweakUI v2.00 for Windows XP/XP MCE [564 KB].

TweakUI v2.10 for Windows XP SP1/XP MCE/2003 [147 KB].
http://download.microsoft.com/download/f/c/a/fca6767b-9ed9-45a6-b352-839afb2a2679/TweakUiPowertoySetup.exe


Manual registry edit to enable/disable the disk optimization:

HKEY_LOCAL_MACHINE
\SOFTWARE
\Microsoft
\Windows
\CurrentVersion
\OptimalLayout

Value name: EnableAutoLayout
Data Type: REG_DWORD
Possible data: 1 | 0

Defrag starts always automatically in the background,
when I do nothing with XP over a period of few minutes.
Is there any possibility to switch off this functionality?
