At least that's what I assume my HDD is forever crunching away doing and it's driving me nuts now TBH

So can this blasted prefetch malarkey be turned off or at least halted in the registry?
 
do you mean the indexing vista does to speed up searches? you can turn it off under performance settings in control panel iirc, it will settle down after a few days of use though
 
It's mainly Indexing and Defender, Superfetch doesn't crunch much at all in comparison to those two.
 
I've never seen indexing crunch, kept it on since the install.

Superfetch only does it for (the crunching/ hdd seeking), first minute after bootup or after shutting down a game but the pc is still fast while it's doing it. It would only be very stupid to turn it off unless you don't do anything with your pc except to browse new uncached pages all the time, as it very much boosts windows speed.

Or do you mean XP's prefetch? I have no idea.

Oh and the automatic defragger does it when my screen turns off ( after bout 2 hours of no activity) even if I turn off automatic defragging lol ( unless dfrg.exe or something like that is owt else, but it's that app according to the resource browser after I come back to my pc that causes the crunching)
 
If you're talking about Vista's SuperFetch, don't turn it off! Don't think you can anyway, but it would be silly too as it's one of the great things about Vista. OK, so you wait a few more seconds at logon but then your whole session is quicker.

If you're talking about indexing/defragging then fair enough I guess, though I leave it on.

Is this a new install of your OS (and is it Vista or XP)? If it's a new install of Vista the constant hard disk use is perfectly normal and it will do this for a few days while indexing your files. After these first few days it dies down and you won't notice it.
 
superfetch will keep the hd grinding away for nearly an hour even will your trying to play your game or use whatever app. Leave the normal pretech enabled, but its easy enough to dissable superfetch in services.msc if you want to. Indexing wont likely slow anything down since it only scans your user folder once on first boot by default.
 
disable defender real-time scanning, stops it scanning everything, so speeds up your machine.

tweak the indexing settnigs so it only scans folders you want it to (it won't scan all the time)

leave superfetch on, it 'crunches' for a few mins on startup, that's it -i only use sleep mode with vista now
 
whatever it is, It lasts about five minutes if the PC is left idle at switch on.

Yes it's a fairly new vista x64 install, but not that new, maybe 3 weeks or so use so far.

Cheers for the info so far, some leads there anyway.
