Okay, so I have a macbook that is roughly 3 years old. Earlier today I popped in a blank disc to burn a cd, and it wouldn't read the disk. I then found the trick where you press and hold the trackpad and it would manually eject the disk. I rebooted, and tried it, but it automatically went to the bootup screen with a loading bar towards the bottom. I waited a bit to see what happened, but the loading bar stopped so I held the power button to hard boot it and to try again. The second time the disk did pop out and it went straight to the loading bar with the spinning thing above it. When it hit roughly 2/5 of the way, the bar would leave, but the spinning thing would stay. I tried a few more times and nothing. I decided to pop in my leopard recovery disks to see if disk utility could help. It took 9-10 tries to get the computer to actually read the disk. I would press option and it would only show the macintosh hd (this is important). I finally got to the disk utility and when I attempted to repair it said "invalid key index" and "rebuilding tree-B" or something like that. After a few minutes it said it failed. I tried it a couple more times and nothing. I searched around and finally found my snow leopard disc, and i decided to do an archive and install since i did something wrong involving the loading bar in the begining and must have corrupted some files. Now that I have my disc, I pop it in and it doesn't read it. I reboot and press option and only the macintosh hd appears. I reboot and try pressing 'c' and nothing happens. I also tried cmd+option+shift+del and nothing. Anyone know anything I can try at this point?
