- - **-3:** No SD Card detected. Re-insert the SD Card and try again. Make sure the SD Card is in FAT32 format. If the error persists, try blowing into the SD slot as it can get dusty inside.
+ - **-3:** No SD Card detected. Re-insert the SD Card and try again. Make sure the SD Card is in FAT32 format. If the error persists, try blowing into the SD slot as it can get dusty inside. 
 
  - **-4:** SD detected but could not mount. Check to see if the SD is using MBR and not GPT. Also, check to see if there are any other partitions on the SD Card and merge them into one primary partition.
 
  - **-5:** Missing files on the SD. Check to see if your SD has Homebrew Launcher located in <code>/wiiu<wbr>/apps<wbr>/homebrew_launcher<wbr>/homebrew_launcher.elf</code>.
 
 ### Browser errors
 
- - **FSGetMountSource failed:** Same as -3 above, means no SD Card detected. Re-insert the SD and try again.
+ - **FSGetMountSource failed:** Same as -3 above, means no SD Card detected. Re-insert the SD and try again. This could also mean that the SD card is locked (Slider is down instead of up) or the SD card label is "WIIU", which is stated in the guide causes conflict. If it's not any of these issues, refer to the last suggestion from -3.

  - **FSOpenFile failed [...] payload.elf:** Missing payload file on SD. Make sure you have payload.elf in the wiiu folder.
 
  - **FSOpenFile failed:** Missing `homebrew_launcher` on SD. Make sure you have `homebrew_launcher.elf` in the <code>/wiiu<wbr>/apps<wbr>/homebrew_launcher</code> folder.
 
+ - **SD Mount Failed:** Similar to -4, the console recognizes the SD card but could not mount it. Make sure it is formatted properly. Also, your SD card is more compatible with reputable brands (i.e. SanDisk, Samsung, Lexar, etc.) and less likely to have issues.
