• Instead of choosing DISABLE WRITE PROTECTION, I had to choose DISABLE READ PROTECTION
  
  
• Instead of using the rotary encoder wiring diagram shown in the video, I used the updated wiring chart at the FlashFloppy webpage (see the section titled KC30 Rotary Header re: silkscreen location JK & J8) https://github.com/keirf/flashfloppy/wiki/Hardware-Mods#kc30-rotary-header

• It costs about $10 (USD) more than a standard GOTEK
• The GOTEK factory firmware uses a boring 7‑segment display
• There are very few bells and whistles available with this model
• Using the two button interface is clumsy and difficult to navigate
• It's in an ugly tan color case... not black to match the Roland scheme

• SFR1M44-U100K
• SFRM72-U100

• The original 4‑wire power cable for the FDD inside the S‑760 will not reach from the Main Board to the new GOTEK. You will need to perform a simple modification to extend the power cable and make it a couple of inches longer or buy a 4-pin extension cable or buy some TE‑Connectivity® connectors, a crimp tool and make your own FDD power extension cable

• It is important to use a quality brand USB‑A to USB‑A cable. Some inexpensive USB‑A cables do not use enough wires and will not work properly because they only have two wires (one for Power and one for Ground). A quality brand USB‑A to USB‑A cable will have four wires (Power, Ground, Data IN, Data OUT). Some manufacturers do this to save productions costs by using less copper
  
  
• Sometimes a GOTEK will not be recognized if it is plugged into an external multi USB hub. Try plugging it directly into one of the main computer USB ports
  
  
• If you have installed any drivers that were on a CD-ROM supplied with your GOTEK... you will need to remove them. These generic device drivers will interfere with the DfuSe USB Device Software and cause multiple issues

• Run the Disk Utility application and choose the USB stick you want to format
  
  • Select Erase then set these options in the pop‑up window;
    
    • Name: (Your choice ‑ You can leave this field blank if you want)
      
    • Format: MS‑DOS (FAT)
      
      • (Do Not Use ExFAT, OSX Extended, GUID Partition Map or Apple Partition Map)
    • Scheme: Master Boot Record
      • NOTE: If you don't see Scheme as an option, turn on "Show All Devices" using the drop down "View" selection (circled in red)

You can verify the USB stick was formatted using MBR by looking at the "Partition Map:"

• Right-click My Computer
• Left-click Manage
  
• Left-click Disk Management
• Select FAT32 and verify it is formatted using the MBR option using this guide
  • NOTE: I've had mixed results using Windows XP. Sometimes it won't format using the MBR option so...... Keep Trying Until It Works

• Run the Disk Management program by clicking the START button and enter diskmgmt.msc
  • In the Upper Section of the window where all the disk drives and CD-ROM's are listed
    • Right-click on the USB Stick listed under the column named Volume
    • Left-click on Format
    • Select FAT32 and Default then press the OK button
  
  To verify the USB stick was properly formatted using MBR, from the same window for the diskmgmt.msc program
  • In the Lower Section of the window where all the disk drives and CD-ROM's are listed
    • On the far left side of the window, Right-click on Disk# where # = the USB stick you just formatted
    • Left-click on Properties then Left-click the Volumes tab at the top
      • Note: In some cases, you might also need to click on the Populate button to display all info
    • Look at the info displayed under "Partition style:" and it should read Partition style: Master Boot Record (MBR)

• The MBR option was replaced with GPT on this crappy Windows O/S version so a third‑party app is needed to format the USB stick
  • A free utility called RUFUS enables a USB stick to be formatted using the MBR option
  • Click here for a screenshot of RUFUS showing the MBR parameters needed to format your USB stick

• Run the Disk Management program by typing diskmgmt.msc in the search text box field at the lower right on the Desktop
  • In the Upper Section of the window where all the disk drives and CD-ROM's are listed
    • Right-click on the USB Stick listed under the column named Volume
    • Left-click on Format
      • Volume label: (Your choice ‑ You can leave this field blank if you want)
        
      • File System: FAT32
        
      • Allocation unit size: Default

• * Adding this extra "interface" parameter tells the GOTEK to operate in the S‑760's "Dual‑Purpose FDD Mode". This enables a GOTEK to load 720KB and 1.44MB disk files. Without this extra parameter added to the FF.CFG file the "Not S‑760 System Disk, Please Change Disk" error appears on the screen and the S‑760 will not boot
