@Eddy ~I don't have the disc with me, although I believe that my parents have stored it with the rest of the discs that it came with at my house (unfortunately, I'm a plane ride away at college). I repaired disc permissions twice now. Nothing seems... substantial with the repair? Most of it seems to just be stuff with QuickTime.
@Mike + PMB ~yikes, that doesn't sound good. If I do end up having to get it replaced, will the whole computer basically be wiped? I'd hate to have to go through that again. I'm trying to set up a quick file back up on my older 500gb external HD right now. I'll see if I can get this to work.
Thanks for the quick responses guys. I'll try to post updates as things happen.
Edit/ starting up the Time Machine for the first time in a while.... ugh. This is going at a rate so slow that it'd probably take longer than a day to finish.
After about 15 minutes of backing up, we are at: 17.6MB of 28.52GB.
....crap, while typing this. Error message: "Unable to complete backup. An error occurred while copying files to the backup volume." ~Apparently it couldn't copy my files to the external HD I have? I really don't know what to do at this point. Should I attempt to backup my files again?
