    I have a Snow Leopard install USB from one of the old 2010 MacBook Airs, but I will probably never use it again because I'm running Lion and have no desire to downgrade. It is really cool and I want to be able to use it for my own purposes. The only problem is that it's formatted as a read-only device and I can't format it in Disk Utility.

    I've searched around and have even tried the chinese SMI Mass Production Format tool but it does not work for me.

    Any ideas on how I can force format this to be used as a regular USB flash drive? Any help is appreciated.

    It's a read only USB! It's designed to have the same thing forever and ever. Apple made sure you can't delete or format the thing.

    I did it before on my brother's Apple USB, it just won't work on mine. I KNOW it can be done, just can't figure it out.

    lol. You can unlock it with SM32Xtest (Windows). It's not really "read only."

    On a slightly unrelated note, does anyone else wish Apple would sell us these things? I'd buy a 64 gig one in a heart beat, and various other sizes for various other uses as well.

    This way worked for me. Thank you!

    That would be the greatest thing ever. I love them so much that I went on ebay and bought 3 more. Perfect for keychains, super thin, very fast read speeds - and they're SO COOL!

    I tried to unlock mine but once I start the scan on sm32Xtest after 42 seconds it says FAILED
    then I checked on my Mac and Disk Utility doesn't see it because it's still a read only disc.

    What went wrong?

    Problem solved. I downloaded the sm32Xtest file from another source and it worked like a charm.:)
