I have Snow Leopard and 134.6GB available disc space on a 320GB drive.
i have a 4.7GB DVD-R in the drive and selected to download the DVD - Universal files when prompted.
After clicking 'Burn' it says "preparing image" for half a second and then reports the following message:
"There was a problem preparing the disk image. Check that you have sufficient disk space and try again. If the problem persists, please report the problem to Coriolis Systems."
Would really appreciate some help here, I only wanted the software to do a full defrag from boot and this makes that impossible!
