    Hi, I just purchased a new USB key, and I just formated it in MAC OS journaled, and the I formatted in MS-dos FAT,
    here is the problem, MAC OS can see the USB key ... but when I want to us it in Windows ... it doesnt see it at all ....

    Weird coz before I formatted in MAC OS journal ... Windows could see it ...

    Anyone know how I could repair this ?

    Please clarify: is it currently formatted as FAT32 or HFS+? Windows does not even acknowledge (without a program like MacDrive) that an HFS+ volume exists.
    If it is FAT32, than both windows and OS X WILL see it. If they don't, you have a problem with the drive or the USB port, and you should try restarting.

    Insert it in the Mac, then format it as FAT32.

    It's MS-DOS.

    The whole drive must be formatted as PC, not just the partition.

    You must not use a Mac partition table.

    In Disk Utility, click Help and search for the word "format". You'll see a link for "Formatting a disk for Windows computers"

    Did you select the whole drive or the partition?

    Did you partition it with MBR (Master Boot Record)?

    Open Apps/disk utility/and high light that disk. Click on erase and choose MS-Dot (FAT) and format.

    Windows should see it.

    Open disk utility, select the disk and then the Partition tab. Select "1 partition" from the drop down menu. Click the option button and select MBR (Master Boot Record). Click Ok. Then select the MS-DOS format from the other drop down menu and then Apply. Let us know if it works.

    One thing that I just thought of... Where are you plugging in the stick on the PC? I recently had a problem with a computer not seeing my external hard drive when I plugged it in to the non-powered ports on the front of the box.

    Make sure that you plug it in to a (normal) high-powered port on the back of the PC if it is a desktop. That, and PLEASE restart the PC. Some times windows has some sort of issue seeing drives, that magically goes away after a restart.

    lol that sounds like kind of a personal question man... Not sure that these are the appropriate forums to be discussing the size of one's "stick", if you know what I mean :D

    Format it as FAT16 (upto to 2GB) or FAT32 in your PC.

    Do other USB devices work on the same PC, in the same USB port? (make sure it's something with the particular USB drive and not the PC in general)

    If you read the OP's post? If Windows can't recognize it, it can't format it.

    "If Windows can't recognize it, it can't format it."

    That's not necessarily true.

    In Windows go to System Control > Administrative Tools > Computer Management > Disk Management. There you should see your drive, even when unformatted. Right click on the drive, and choose Format or Partition.

    Just because it doesn't mount doesn't mean Windows won't see a "USB mass storage device" or some such thing attached and be able to format it. The OP didn't provide such details. If Windows can't even see that the device is attached, then it's a whole different problem.

    ....which is what "doesn't see it all all" typically means. All we can go on is what the OP stated, and based on that, Windows doesn't recognize the device at all, which would indicate it also can't format it. If the facts are otherwise, the OP didn't specify.
