I'm interested in any info anyone can offer about encrypting volumes or whole disks --- just what does encryption do (and what doesn't it do). I've read a little about encryption here and on other sites . . .still not exactly sure what level of protection it offers, especially while online. Apparently it's not the end-all to pc security, otherwise it seems everyone would use it and there would be no need for AV and firewall software. I've been experimenting with "Truecrypt", and would like some more info before I proceed any further. Thanks.
