I'm totally lost! I've tried everything I can think of and still keep getting the corrupted data file error when I try to open a dmg file on my iMac. I've run Disk Warrior, Drive Genius and Disk Utility. Early on, Disk Utility and Drive Genius found and corrected a few errors. Now everything is reported as 'just peachy', yet I still can't open a disk image file. Short of explosives, I don't know what to do.
Any suggestions? Amanda On Dec 2, 2011, at 4:12 PM, Amanda Ward wrote: > J. R., Bruce and Jim… Many thanks! Y'all have given me a weekend's worth of > tinkering.
