The following question was posted by a visitor:
Is there such thing as encrypting your hard drives so that if you did get someone trying to access data via online hacking it would make the entire harddrive encrypted: instead of just encrypting a folder, the entire system i mean.
Yes, you can use http://www.truecrypt.org/
As always, make sure you take a backup of your data first. Create a recovery key if the option is available, incase you lose your password. Always test first.
