Just an update. Apparently my hard drive is getting ready to fail after all. After backing up all my files, I decided to create a set of recovery disks to reinstall the OS after I replace the hard drive but I seem to have run into a problem. The program told me I would need 3 disks. I successfully created the first recovery disk but then I had to exit the program to do something else. It told me it would resume where I left off so I didn't think it was any big deal. I reopened the recovery disk program and went to create disk 2 and instead, it started creating another disk 1, despite the fact that the program said it would only allow me to create one copy of each disk. I don't want 2 disk 1s. Anybody know what's going on here?
