May I pick your brain? External IDE drive,- removed from a dead PC. chock full of files. Mounted via USB perfectly on the 'Vista PC and I am pretty certain the drive mounted on new MacBook Pro running 10.6.2 (using Wiebe's external docking device) Many documents were present and viewable on the Mac Drive then placed in plastic bag on counter in dining room Two weeks later I purchased a USB enclosure for the drive. Installed easily. Powered up immediately, I can hear the drive spinning. Connected to the same macbook pro to which the drive had , two weeks earlier been connected, and mounted. Except now the drive does not mount Power is on I can hear the drive spin But now the drive does not mount Disk Utility sees the drive but it does not mount Mac asks me if I want to reformat the drive as it is unrecognizable Drive Genius and Disk Recovery see the drive but can find no files. What might have happened? Did damage occur by putting in an enclosure? I have put numerous hard drives in enclosures and never had this problem. I know I pushed in the cables tightly and assume that the drive would not power nor the drive be seen if IDE ribbon cable and power line were not properly fastened. I am puzzled Anything I can do? would like to save these folks' files.
