My original question came from looking at Encryption Plus Hard Disk from PC
Guardian (www.pcguardiantechnologies.com) which uses 256-bit encryption to
encrypt both the MBR (pre-Windows) as well as partitions of choice. I wondered
what was done to protect the system over lunch absent a shutdown.
It seems, from various postings, that rebooting is required to get around the
Windows (screen saver) password and that even protecting the BIOS isn't safe.
However, it seems that if a user encrypts both the MBR as well as partitions,
then data is reasonably safe from prying eyes, given that PCG EPHD is effective
on (re)booting.
I haven't heard that it is possible to circumvent the Windows screen saver
password without rebooting, so perhaps the PCG approach makes sense.
