Copied what I wrote from your other post: If you go over to performance there should be a link called "Open Resource Monitor." Click that, and then go over to the disk tab, you can organize it by total bytes/sec and see what process/service is using the most disk.

If it's an HDD, it could be a sign that it's going bad.

It's not, if an HDD is going bad it won't show as 100% usage.

 

100% disk usage in task manager would mean some Windows process is doing lots of reading and/or writing to/from the disk, for some reason...

Alright, but how about if Task Manager was showing 100% usage, but it was only reading / writing 2MB/s of data?

I ended the service host 

the warning message said that windows will become unstable and shutdown

Instead of shuting down it just restarted the task and the disk went down to 3% usage
I guess its all good now (not sure why)

Thanks for all the help though
