    Everybody running firmware 7.1.1? That increased my AirDisk speeds enormously.

    yup, I tried both firmwares many times. Same thing.

    Mark, I have the exact same problem. Seagate FreeAgent as well, but I doubt that matters. Newly formatted on a Mac as HFS journaled (does that make a difference?) and plugged into the airport (w/ latest 7.1.1 firmware). Everything looks good, checked the airport logs and no disk errors were reported. I get about 420Kps write speed while connect via ethernet (not wireless).

    Anyone who might know what's going on please tell us!?

    I found my issues was related to the USB hub i was using, so try using different USB devices and see if that helps

    I've got the drive directly attached to the airport. Super slow! Maybe the airport is defective? Because the drive is super fast when attached to a PC or Mac. Anyway we can tell if the usb speed is at 1.1 or 2.0? Thanks everyone.

    This could mean that the AirPort does not support that external case 100% see if anyone else has same problems on their airport with that case, you might have to wait for a new firmware.

    But for the short time if you have another case or can get another case i would try that

    Thanks semaja2, I finally got it to work. After doing some googling with "airport disk usb performance" I found that others had better success with formatting without journaling. So I reformatted it to "Mac Extended", and plugging it back in. Now I'm getting roughly 7MBps!

    However, not all is perfect. While transferring a 2.6GB file (approx 8 mins) the transfer broke and required a full recopying. Error: "Unexpected Network Error". I was doing this from Vista. I guess this is better than nothing. Hope Apple continues to iron things out...

    Glad to hear its working, i also get that error, but under OSX it just slows the transfer massively

    I can confirm that reformatting the drive to "MacOS Extended" NOT journaled totally fixed the problem for me.

    No disconnect errors for me yet.

    I don't think this is a widespread problem.

    Most people on this forum have a problem, but they are here because they have a problem, not because they are typical.

    If you are getting poor airdisk performance, and you have the most optimal disk format, chances are the problem is wireless throughput.

    Poor wireless throughput can be down to...
    1) Poor signal strength
    2) 2.4Ghz interference. Either other networks or appliances.
    3) Network problems (IP clash etc)

    iStumbler would be a good place to start.

    Is airdisk still slow over ethernet?

    Hi everyone,
    I've come to this thread as I am having the exact same problem as others here. New Macbook, new Airport Extreme with 7.1.1, and new miniStack v2 400GB hard drive. Running 802.11n reporting 130Mb network link and getting excellent computer to computer throughput. HOWEVER, using the Airport disk (with the miniStack) provides about 500Kb/s to 900Kb/s maximum. There is most certainly a firmware issue with the Airport Extreme.

    Apple - any information about this? My backup over the network took 50 hours to this drive! Thanks.
