iMac 27" -- startup disk corrupt -- no optical drive

[dwnii]

I was playing Starcraft 2 and was getting a lot of lag (unusual). I noticed the HDD was working very hard, so I ran disk utility and got the attached message when using "verify disk"

My comp is first generation and the optical has quit working, which I've read is common with 1st Gen. iMac 27's. Can I boot from installation disk on an external USB drive?

Is there any other way to go about repairing this disk?

I think I've done that from an ext DVD burner on my older iMac since it too has a failed ODD.

Good to know. I've never had to repair a Macintosh HDD before, so I'm wondering. Is it like formatting a Windows HDD? Will I have to re-install everything?

You can either use a Mac supported USB External optical drive or if you have another Mac you can simply boot your into target disk mode and repair from the other Mac (even share the optical drive)
