No

Back it up!
Find another Mac w/ firewire.
Target start your Mac by holding down the "T" key until you see firewire logo.
Attach firewire cable between the computers.
Your hard drive will mount on the other computer and you can copy over any files you would really miss.
Often bad blocks in one's computer can develop in important places like the boot sectors.
You may have to do a "Archive and Install" if disk repair, permissions repair, all else fails.
Protect your data.
Applications are easy to reinstall.
Best of luck!
