    This is really awkward. It use to be able to transfer 1gig of data to my external in less than 2 minutes. Now its a miracle if it can even load up finish transfering before an error occurs. It use to be able to chug at about 30MB/s and now its just slowly transfering data and less than 1MB/s!!!!

    I know it isnt my External's fault because just loading up 12 songs onto my iPod takes roughly 5 minutes!


    Anyone think they might know the source of the problem?



    I have a MacBook, it most definitely isnt going at USB 2.0 speeds, not even USB 1.1! :mad:

    Have you tried a different port? What else are you doing on the system at the same time? Is it running off batter power? :)

    From my understanding, any USB cable, even ones bought 10 years ago long before USB 2.0, is USB 2.0 capable. The USB 2.0 cables are just a gimmick by manufacturers to get you to buy more.

    That's a good question because it sounds as if it's running at full speed, not high (or hi-) speed, as if it had a USB 1.1-compliant cable.

    The iPod is getting slow transfer speeds and we know the iPod cable is USB 2.0 compliant. :)

    Yeah... both ports are slow, and it was plugged in.


    When I was transferring I had nothing opened, when I was transferring to my iPod it was just iTunes opened.

    Okay, it's a bit of a long shot but maybe try resetting your PMU to reset some of the port settings.

    What I've found is that the first time I sync my iPod touch after a reboot of my machine (Intel iMac) I get really fast, USB 2.0 sync speeds. If I sync again a little while later then I get extremely slow sync speeds. Somehow the USB port seems to get switched into 1.1 or 1.0 mode. I haven't done enough experimenting to find out exactly what causes the switch. My suspicion is that when the iPod goes to sleep it affects the port.

    This happens whether I attach directly to a port on the back of the machine or on a USB 2.0 hub.
