A few months ago I had a problem opening disk images, very much like Brett's. A discussion on WAMUG seemed to solve it, however it turned out to be temporary, or, I think, only certain disk images would refuse to be opened, but others were openable. When I tried to open the reluctant ones with Disk Utility, a message appeared: Invalid BS_impBoot in boot block: 66671 No partition map
When a whole series of disk images refused to open, I did some googling and discovered quite a few people also had problems, and they all seemed to be related to usage of a Lexar flash drive. I had a Lexar flash drive briefly - I loaded photos on it and took it over east when I visited family. To my great disappointment, when I tried to unload the photos, they couldn't be found. They were visible on my computer, but not on any other that I tried. So I ditched that drive. However, when I read that someone had solved the disk image problem by throwing out this file: System>Library>Extensions>LexarFileScheme.kext I had a look at my System Library. I didn't find that particular file, but there were 2 others: LexarFilterScheme.kext and LexmarkUSBMerge.kext So, out they went, flushed down the trash. After a restart, I can open any disk image I like. I hope that this information might help others who have had disk image opening problems. Cheers!
