My understanding when I read Jeff's note was that his enclosure was powered from an external 5v & 12v AC->DC power supply, not from the USB port. What was confusing to me about Jeff's situation is that apparently the 2.5" drive worked with USB (and I assumed also with eSATA ... though he may not have checked this). However, when he put the 3.5" drive into the enclosure it did not work with USB but it *did* work via eSATA. If it was strictly an enclosure power supply issue then I would expect the 3.5" drive to never work in the enclosure. Or USB to not work for either drive. I can't come up with a good rational for why the 3.5" drive would work with eSATA but *not* work with USB, other than possibly the 3.5" drive exceeded some GB capacity limit of the SATA->USB adapter/converter?? Oh, well. Maybe it's gremlins? Makes as much sense to me as anything else at this point. -irrational john --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
