Recently, I've had an issue with my Dell Inspiron 580 computer where it was unable to boot up. I get a message about a hard drive self monitoring system has reported that a parameter has exceeded its normal operating range. From there I hit F2 to continue and it just goes into the BIOS menu and even if I restart the computer, I just get the same hard drive self monitoring message.
I wanted to find out if my hard drive might be toast or not and I wanted to also try to backup my personal data before replacing the hard drive. I'm booting from a CD-ROM Linux based program called Parted Magic, but I'm unable to mount my internal hard drive so I can backup my data to my external hard drive. I'm not sure what commands to type in the terminal. I don't have a lot of experience with Linux based commands.
