You REALLY need to know what your doing if your going to play with this app. If you end up with strange things happening like, can't boot up your slave drive, or having trouble ejecting disk images, then it's this app doing it. I installed this to test and then forgot about it. When crap started to happen I didn't know why. After weeks of asking everyone I found it on my own. I trashed anything that was PGP. All was just about OK again. Some lingering damage, but better then it was. Oh, you won't get any support from these people either. It's the worst I've seen.
