A 2-digit error code defined by the FatFS library.

In HxC Compatibility mode this probably means you have stale slot assignments in HXCSDFE.CFG. You should copy a fresh version of HXCSDFE.CFG to your USB stick and reassign slots using the Autoboot file selector.

In other cases this error usually indicates bad physical media or a bad filesystem. Try formatting or replacing your USB drive.

A 2-digit error code defined by the FlashFloppy firmware:

• 30 Disk Full: Some writes were lost. Delete some files or use a larger USB drive.

• 32 Bad HXCSDFE.CFG: The config file is invalid or unsupported. Copy a fresh version to the USB drive.
• 33 Bad IMAGE_A.CFG: The last-image file has become corrupted. Delete it from the USB drive and it will be automatically recreated.
• 34 No entries to navigate:
  • Direct Navigation mode found no valid directories or image files to display. Add some valid image files to the USB drive. Subfolders are accessible only when using an LCD/OLED display.

More rarely, this can occur when the Gotek is powered separately from, and earlier than, the host machine. In this case the error will clear automatically when the host machine is powered on. It is recommended to avoid powering on the Gotek after the host machine.

Over-current condition on the USB port. The port is powered down until a button is pressed.
