To use BeatBuddy content in BeatBuddy, the SD card itself must be properly formatted, or it will show as “no SD card” when inserted into BeatBuddy. BeatBuddy may even not start up if an incorrectly formatted SD card is present inside the BeatBuddy when it is powered on.

BeatBuddy works best with standard SDHC cards in the 4 GB to 32 GB range. Class 10 cards with 90+Mb/s are recommended for faster read and write speeds. New compatible cards usually come ready to use and should already be formatted as FAT32/MS-DOS (FAT). Very large cards, especially SDXC cards over 32 GB, are more likely to cause problems

Before you start #

Use this checklist first:

• Use your computer’s SD card reader when possible, rather than the BeatBuddy’s USB connection, for preparing the card. This is a must for BeatBuddy 2, as it doesn’t have a USB connection.
  
• Use a standard SDHC card

• Use a card between 4 GB and 32 GB

• Prefer Class 10

• Make sure the card’s lock switch is in the unlocked position

If using a brand-new, non-formatted SD card #

In most cases, a new compatible SDHC card does not need to be reformatted first. New SDHC cards are normally already formatted properly and ready to use.

If the new card is not recognized #

If the card is new but BeatBuddy still does not recognize it, even though it is in FAT32, format it manually following the steps outlined in the section below.

If re-formatting a card previously used #

If the card was previously used on another device, formatted incorrectly, or BeatBuddy shows errors such as “Invalid SD card” or does not recognize the card, it is best to fully erase it and recreate it properly as a single FAT32 partition.

Format on Windows #

Open Command Prompt as Administrator and run, one line at a time:

diskpart
list disk
select disk X
clean
convert mbr
create partition primary
select partition 1
format fs=fat32 quick
assign
exit

Replace X with the correct SD card disk number.

IMPORTANT: Make sure to specify the correct disk, as it will be erased!

After the SD card is properly re-formatted, you can install a valid BeatBuddy project onto it.

Format on Mac #

1. Open Disk Utility
2. Go to View > Show All Devices
3. Select the physical SD card
4. Click Erase
5. Choose:
   • Format: MS-DOS (FAT)
   • Scheme: Master Boot Record
6. Click Erase

Now that the SD card is properly formatted, you can install a valid BeatBuddy project onto it.

Important: if you are formatting manually, aim for:

• 1 primary partition
• FAT32 / MS-DOS (FAT)
• MBR (Master Boot Record), not GPT
  This layout is the only choice for BeatBuddy compatibility. The MBR recommendation is critical and is based on real-world compatibility testing. Without it, the SD card will not work in BeatBuddy, even if formatted in FAT32.

Troubleshooting tips #

If BeatBuddy still does not recognize the card:

• Confirm the card is SDHC, not SDXC
• Confirm the capacity is 32 GB or smaller
• Confirm the card is unlocked
• Confirm it is formatted as FAT32 / MS-DOS (FAT)
• Avoid specialty video-optimized / V-rated / high-speed camera cards, which are reported more often in compatibility issues
• Make sure your BeatBuddy project is installed in the root of the SD card. Assuming your SD card drive is “D”, a valid BeatBuddy project properly installed on the SD card would have the following folder and file structure.
  
  D:\SONGS\
  D:\DRUMSETS\
  D:\EFFECTS\
  D:\PARAMS\
  D:\Some BeatBuddy project.bbp

Summary #

For best results, use a 4–32 GB SDHC Class 10 card, and if formatting is needed, format it as FAT32 / MS-DOS (FAT) with Master Boot Record (MBR) and a single primary partition. Then load your BeatBuddy content onto it.
