I didn't have any of the things mentioned in your advice. The hdd in the 1st bay is apparently the one that's bad. I figured this out after a lot of trial and error. But my laptop did not like the 500gb hdd to be in the 1st bay. I took the 250gb hdd out of the 2nd bay, put it in the 1st bay, and put my new 500gb hdd in the 2nd bay. I had to request a copy of the recovery disks to restore my system. Everything seems to be working right now. I'm keeping my fingers crossed. Thank you everyone for all your advice.
