Your answers are in the above posts with one important note to everyone.
One last thing can cause games to freeze from the hard drive...
The directory names and depth.
I've found that with certain titles if you use a long directory name with spaces the games will freeze or refuse to play.
We've covered this before in other threads so I forgot to mention this again.
Keep those directory names SHORT just in case, 8 characters. Don't nest the directories more than you have to.
BTW:
DOA3, The Thing, WWF Raw all work properly from the hard drive.
