When I hook them up in an external enclosure some show up in Disk utility (only the first line, the second does not show on the left hand side in the listing of drives) and they don't mount. I can't run first aid and it looks like I can reinitialize some of them but not others. Before I try the reinitialize option I would like to see what is on them first. Drive Genius and Tech Tool do not see them either, only Disk Utility does so far. The others mount and run fine. I have tried different USB and firewire ports and cables, a different enclosure as well with no improvement.
***** I encountered this problem yesterday. The issue in my case turned out to be insufficient power to the external drive enclosure, which when enhanced with a secondary USB (I assume it might as effectively been through an AC power brick) power supply to the 5 volt DC power receptacle on the enclosure, the seemingly unreadable drive suddenly immediately became readable, and I was then successful in transferring the data on the drive in the enclosure to my new MacBook. In my case, the extra power was supplied by a cable with a USB connector attached to the second USB receptacle on the MacBook, which has the right size cylindrical plug for the drive enclosure's auxiliary power receptacle at the other end. It might be worth note that this same external drive enclosure, containing the same hard drive, when used via FireWire on my PowerBook G4, without any external power supply, is able to boot and operate the PowerBook G4. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
