Can you encrypt a hard disk with gpg? Is there any tool to do that?

Most OS'ses allow you to access a HDD as a file. So technically it is possible. I suspect that it will not do what you want though. –  Hennes Sep 3 '12 at 12:27

Why do you want to do that? What is your use case? –  Oliver Salzburg Sep 3 '12 at 14:49
    
The commercial PGP used to have "PGP Disk". –  grawity Sep 3 '12 at 16:42

Even if it's possible, it probably isn't a good solution because disk encryption needs to be a transparent layer between OS and disk due to the continuous I/O.

It's certainly much more practical than encrypting each and every file individually and has the same performance. –  ssg May 29 at 22:43
