After Disk Utility couldn't repair my hard drive, and I was told to erase and reformat, I attempted to reinstall Mountain Lion but I keep getting this message saying "This disk is locked".
Any help would be greatly appreciated, thanks.

Hi Linc Davis,
You say there are ways to back up a computer that isn't fully functional. Help! The only way I can get into my computer is via command>r. I assume I need to back up my computer before I do a reinstall. How do I do that. I tried disk utility repair and got 'Invalid node structure', 'Disk full error' and 'Error: disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed up files'. I have a Seagate external hard drive. I cannot get to my desktop at all. Can't reinstall Lion because the HD is locked, although I think I need to back up first if possible. I have tried double clicking the HD in the utilities window and nothing happens. FYI, when starting the computer with no commands I get the apple, the progression bar and then it shuts down. Thanks in advance!
Thanks for the help, I've already backed it up. But if I can't repair it or reinstall, what are my options?
That is what my iMac is doing!!
