setup : 2x iMac 24" 10.5.6..wired to airport Xtreme, Iomega 500 GB HD connected via USB this drive worked fine and has all the pics on it and was used to backup both iMac's via Time Machine. Today the Airport Xtreme (AX) gives us a flashing orange light and informs us that the 500 GB Iomega disk needs to be connected to the mac and needs to be repaired. so...we did, with a "disk appears to be OK " message after 'repair' mounting from within Disk Utility gives us : "The disk 500HD could not be mounted. Try running First Aid on the disk and then retry mounting." (we did just that...!) We also tried "Drive Genius" with the same results. whether we hook the drive to the AX or directly to the iMac...no mounting. The drive (and it's partition) does appear perfectly in both 'Disk Utility' and in 'Drive Genius' (The iMac does mount other USB items like mem-sticks, camera's just fine.) anybody any ideas how to get this working again ? thanks !
