Pros: I think DriveCrypt is one of the best encryption products out there. The features of the software are helpful and easy to use. This software allows both, the encryption of an entire Hard Disk partition (the way it does it is by first of all formatting that partition and after that the user can add data to be encrypted), as well as the creation of a virtual container file that will store all the encrypted information.
DriveCrypt allows the creation and encryption of invisible container files that will store all the encrypted information.
This softwares encryption algorithm can go as far as 1344 Bit encryption strength, keep in mind that this is millitary strenght encryption.
These are just some of the features of DriveCrypt. I am very pleased with it and I recommend it gladly.
