Dude !
It's NOT the cache and it's NOT the drives. It's Windoze. When windows shuts down on a warm boot it doesn't clear the memory. Period!
You have to shut the computer "OFF" for 15 second then back on to clear the memory (drive cache in your case). This is an inhereint problem with Microsoft O/S's which includes NT4, 2000 workstation and Server.
Unix / Linux (as stated in a previous message), shutdown diffrently, which is why a warm boot works. Keeps from dimmin' the lights each time too !
I'm sorry no one in those other forums etc. told you this.
