How do I switch off auto-defrag in Vista ?

[Ochaye]

I've unchecked the "run on a schedule" on Vista's Disk Defragmenter
but it will still automatically defrag when the machine is idle, if it considers it necessary.

"virtual" software I'm using will be bolloxed if a defrag occurs while I'm using it.

So how do I disable auto-defrag in Vista ?

I didn't see this option on the Tweaker,

I'm prepared to alter a registry value to switch auto-defrag off.

It's probably staring me in the face, but I cannot see the bold items ...

To disable Vista defrag feature :
Start > Control Panel > System and Maintenance > Administrative Tools > Defragment your hard drive >
grant permission > Unclick Run automatically if you want this feature disabled > OK.

I'm using Vista Windows Home premium, if that's relevant.

Pehaps there's a line I can put in the command prompt which will switch off auto-defrag ?.

I suspected a registry change was required ... Disabling Disk Defragmentation

thanks anyway Andy.

Despite changing the registry value to "N" for No, it just did an auto defrag when the machine was idle for +10 minutes.

Any other suggestions how I can switch this bloody auto defrag thing off.

[Vista home premium, running on Dell 1525 if that's relevant]

Click Start then Computer
Right Click the C: Drive
Click on Properties
Select the Tools Tab
Click on Defragment Now
Uncheck Run on a schedule
this might help

Uncheck Run on a schedule
this might help

Thanks Seti,
but like I said in post #1 I've already done that and it doesn't disable the auto-defrag when idle.

If I could find the defragment menu option HappyAndyK mentions I'd be laughing ...

To disable Vista defrag feature :
Start > Control Panel > System and Maintenance > Administrative Tools > Defragment your hard drive >
grant permission > Unclick Run automatically if you want this feature disabled > OK.

but this menu option does not seem to exist on Vista home premium.

PS I found a possible reason why "N" for No auto defrag didn't stop auto defrag ...

Check to disable background disk defragmentation.
Note that if another component h[a]s the two registry keys within it that this option is attempting to disable, then checking this option might have no effect

Configuring FBWF Offline

i.e. there could be duplicate registry value(s) somewhere with "Y" for Yes.

Sorry for the delay in replying. I have erred. It should not be 'Run Automatically ..." but 'Run on a schedule...' which you seem to have already done. I guess I had posted in the earlier thread without remembering the exact wordings.

Let me see if I can get outside help with this in a day or two ...
