I tried using a couple different Cool Tip articles about zen imaging to USB drives, but am still having problems. I want to store the c:\ drive onto a different partition on the same hard drive.

Here's the scenario:

40Gig drive:
20Gig windows partition
10Gig ext2-formatted partition
(10gig unused)

I mounted the 10Gig partition, then went into the IMG tool and tried to save the c:\drive image to it but it bombs out almost immediately with "Out of space on destination", even though I know that the resulting zmg file will be far less than 10Gig.

Please tell me what I'm missing.
