    I've had this problem the other way around before but I somehow got it to work before on both operating systems simultaneously. Now, my USB flash drive is found without a problem in XP, but OSX will not find it. I've tried cleaning both the flash drive and USB port, as well as trying multiple ports, and I'm plugging it in directly into my MBP, not using USB hubs.

    Anyone know what I could try to fix this? I need the flash drive present on both systems

    My guess is that it has been formatted NTFS, try using windows to reformat it and make sure you have it set to FAT32.

    Typically if you have a virtual machine, the default behavior is set so only one of them will recognize the removable drive.

    You might want to change the settings / read the manual of parallels.

    Even on a Leopard system it would show up as read only if it were just NTFS.

    I concur. In VMWare at least, if the USB flash drive is grabbed by OS X it is not visible to Windows and vice/versa. Ejecting it from Windows usually makes it show up in OS X.

    The manuals may have some suggestions, but if not. Your best bet is to mount in in OS X and set it as a shared folder in Parallels so under Windows it would be seen as a network drive.
