Encryption help
Hi everyone,
I was thinking of encrypting my external 320GB HD but was not sure how it exactly works. I have some things on the HD already, what i want to do is encrypt everything that goes on my external HD. I have heard truecrypt is a good peace of software but im a bit of a noob when it comes to trying to use it and would be really grateful for some helpfull advice.
If i manage to get this done would it be worth while encrypting my entire desktop HD? its 500gb in size and in 4 partitions. If i was to encrypt this would it slow down performance at all as it has to decrypt files as and when i want them?
Hope you can help
many thanks
