    Lightbulb Removing a GPT Protective Partition and getting your USB Drive ready for USB LoaderGX

    REMOVING THE GPT Protective Partition and Setting up a
    WBFS Partition for USB Loader GX.

    This guide requires that you have access to a Macintosh or Hackintosh running OS X Tiger, Leopard or Snow Leopard.

    This guide will also serve to get a USB drive ready for USB Loader and WBFS for Mac OS X for users. As your drive will most likely be unable to format in USB loader and as of now WBFS for MAC OSX does not support drive formatting.

    Some users are reporting that they purchase a brand new USB hard drive or thumb drive and while it is detected by USB Loader GX it will report that it is unable to format the drive. When you open the USB drive up in Windows Disk Management it will list the drive as a GPT Protective partition.

    It has a Primary fat32 drive formatted on it but you are unable to repartition it at all. The reason for this is that drive vendors are shipping drives partitioned with a “GUID partition table” instead of a “Master Boot Record.” The result is more secure drive and one that mounts quicker and is fully compatible Apple Time Machine. The unfortunate side effect is that Windows PCs simply do not have the ability to alter the partition table.

    GUIDE>
    1. Insert the USB drive you want to use and open up Apple Disk Utility. This is a built in app and is located in applications\tools.
    2. In the left pane highlight the drive you inserted in step 1. You will be able to recognize it by capacity possibly brand. BE VERY CAREFUL!! If you select the wrong drive here you will cry.
    3. You will now have a button available that says Partition, click it.
    4. Click on the “Volume Scheme” drop down menu and change it from current to 1. (You can choose more than one of course like if you want to end up with a drive that has a WBFS partition AND a FAT32 partition.
    5. Next in the “Format” drop down box select MS Dos (Fat) Yes it is fat32, OSX doesn’t even acknowledge fat16 anymore.
    6. Click Options and change the partition scheme from GUID to Master Boot Record.

    7. Click Apply.
    8. When it is done formatting click options confirm you still have Master Boot Record selected, Change the Format drop down again, this time selecting “empty Space” and click apply again.
    9. When it is done creating the now Empty MBR partition unplug the USB drive, pop it in your Wii start up USB Loader GX. It will prompt you again that there is no WBFS partition but this time it will be able to format it.
    10. Pat yourself on the back your done.

    You are now ready to start using USB Loader GX and WBFS for OS X.

    If you didn't skip step 4 then i suspect that your problem pertains to an ios. possibly you still have a stubbed ios. I would start a thread explaining exactly at what point the DSI error occurs. I suspect now you have a problem with USBloader its self.

    Thanks for the helpful tutorial! I'm just having one problem. If I pick FAT32, it runs just fine, but I'm not able to convert it to WBFS, because it jumps straight to the menu. You say to select "empty space" as they option for the format, and by that I assume you mean "free space" because there's no option for empty space. When this happens, I am able to get to the format screen, but it says "cannot be formatted" for the space. What have I done wrong?
