Windows 7 HDD lag?

[Thunell]

Hi!

I recently bought a new computer with W7 Ultimate 64bit.

After startup it runs smoothly but after couple of minutes the
system keeps freezeing up for 3-5 seconds. Videos freeze aswell
as sound and every app. At the same time as the freeze
occurs, the HDD works hard. The HDD lamp lights up and I hear
the harddrive working. Its a WD W-raptor 150gb.

The system is installed just couple of days ago and it worked
perfectly for 1 or 2 days.

Anyone know what this might be?

Sounds like a hardrive problem. Do you have all the Windows updates installed for your system? Try changing the SATA cable around or use another.

Use this tool from Western Digital to test your harddrive. WD Support > Downloads > SATA & SAS > WD VelociRaptor

I have reinstalled my entire system now..

At first, it worked perfectly, but after I tried to move big files
to my secondary disc, I only reach speeds around 20mb/s

I tried to unplug my WD Caviar 1TB SATA-disc and the system seems to
run perfectly.

The problems seems to occur when I try to move big files or download
to the secondary disc.

System starts to run slow, mouse cursor freezes for couple of seconds, apps
stops responding etc.

Really annoying. When I try to install the intel sata utility it says my computer
does not meet the minimum req's for this program.
