    My only suggestion is to mount it on the PC then 'Share' it and pull the data across to your Mac.

    I am also experiencing trouble with my HP USB flash drive (HP v100w) when I try to use it with my new MacBook (OS X 10.6.1). The drive works perfectly and is recognized without trouble on my PowerBook G4, but when I insert it into the MacBook, it does not seem to be recognized (though it is listed in the Utilities and System Profiler info). The only seemingly relevant information I get from a Disk Utility verification is that its S.M.A.R.T. Status is "not supported." (I don't know what this means, but maybe it's important?)

    When I first insert the flash drive into the USB port (either one), its active light flickers, so I know some kind of connection is being made. Does anyone have advice regarding how to get the MacBook to recognize my flash drive so that I can transfer files? Thanks in advance.

    I had the same problem as you SShifrin and found the solution

    1. Open the "Disc Utility" app (Under Applications > Utilities)

    2. Select the USB drive from the list of drives

    3. Select the "Erase" tab

    4. Select a format using the combo box (I chose Mac OS Extended (Journaled))

    5. Select "Erase"

    Now it will be viewable in finder.
