Does your hard drive seem to be working flat out for no reason. Here’s how to find out What’s running ?
1. Press Ctrl/Shift/Esc to open Task Manager,
2. Click the “Performance” tab.
3. Click the “Resource Monitor…” button
4. In Resource Montior, click the “Disk” tab.
5. In the “Processes with Disk Activity” pane, click the “Total (B/sec)” column to sort by total disk activity.
…the process with the highest B/sec is probably the culprit.
