Im having problems booting Backtrack 3 off the CD. i have checked the md5 and its good but when i boot the cd it freezes at "Looking for data directory". i read somewhere that it has something to do with backtrack not being compatible with SATA hard drives, which i have. I have no other hard drives that i could connect instead as some people have suggested. is there another way i could get Backtrack to work with my hard drive like drivers or something? Help would be appreciated, thanks.

PS: i am a complete noob when it comes to Linux, so i would be thankful if you explain throughly, thanks again.
PPS: i did try searching an i didn't find much that helped me.
