I've recently started experiencing a rather menacing problem with my PC. My hard disk is divided in 3 paritions (C, E and F). Yesterday when I turned it on I saw only C but not E and F. I went to Device Manager and scanned for hardware changes and that brought back the partitions. I thought it was gone for good, but today when I started my PC the same thing happened again. Any idea what's causing this and how to resolve it?
PS I'm using Daemon Tools.
