Provided the drive is mounted, yes. and there is no "without slowing
down the pc" - obviously it *will* cost CPU time (you are doing crypto
on each virtual disk sector on the fly), but it shouldn't impact on
bandwidth unless you have a really slow pc. Virtual drives occupy a
drive letter like a normal drive. most (including pgpdisk) have to be
"mounted" while windows is already running - ie, there is nothing at
that disk letter until you run a program and type a password. Some (like
DriveCrypt Pluspack) allow the boot volume to be a virtual volume and be
mounted *before* windows starts running.
Easiest way to find out what you can and can't do is download Scramdisk
or E4M, and play :)
