This alarm becomes active when there is more than one paging file on a single physical disk. This can cause performance degradation – especially on IDE disks. IDE disks allow only a single disk operation to be active on the bus at any time.
Edit me

To rectify the problem:

  1. Open the Windows Control Panel.
  2. Double-click System.
  3. Click the Advanced tab.
  4. Select Performance Settings and change the paging file allocations.
