you are right, but there are so many features that you can do with pgp whole disk encryption that you cant do with trucrypt. Im dealing with a mac, so, if I were dealing with windows, truecrypt has all the bells and whitles for that but not mac. In order to encrypt your HD on a mac with trucrypt you have to copy all the data on to another drive, reformat and then put truecrypt on then put all the info back. with pgp wde, you can encrypt it without doing that. it seems that it would make my life easier. Had i known all this before starting I would have done it different, but since i didnt I want to do it the easiest and safest way possible. but, ill probably just stick with truecrypt..
