I have an iMac with Snow Leopard that shows it is low on disk space. In Disk Utility, I select the hard disk and click "Verify Disk". It gives me an error and says to click "Repair Disk Permissions".

When I click "Repair Disk Permissions", it tells me to reboot the system and insert the iMac's DVD and run the Disk Utility from there. The error message received was:

> 
> The volume Untitled was found corrupt and needs to be repaired. Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk.

I have the DVD with me, but the DVD-ROM isn't working. I have two non-Mac laptops with working DVD-ROM drives and all of them are on the network.

Is there a workaround to fix this problem?
