    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.

    IDE doesn't detect problems on the cabling and prevent the system from booting; thus that could be your problem.

    You may have a short somewhere as well, something pushing up against the controller board causing it to short out (if this is it, it could be the end of the drive).

    Or, there could have been an ESD discharge that zapped something on the controller. Again, would be the end of the drive.

    I would recommend taking the drive out of the case and try it again as a bare drive. If it powers up and works then carefully reinstall it and see if it works. If not, could be the controller of the USB to IDE board in the case.

    would the Mac to ask me to reformat the drive or am I misunderstanding something?

    Depends. Typically I'd say no, but noise can do odd things. Now, has the drive been moved around, or otherwise handled poorly while out of the machine? That could cause it to lose it's mind. Electric fields, magnets, etc can also scramble drives.

    Any possibility it could be the jumper settings?
