What does b00000 - b06409 mean?
The drive displays a boot error code (starting with 'b' on the seven-segment display) indicating a fatal error during the boot-up process. This generally points to issues with the memory module, firmware, or connected external hardware.
Common Causes
- Memory module not correctly fitted or damaged.
- Corrupt firmware preventing successful boot-up.
- Damaged encoder drawing down the control board voltage, causing boot failure.
- Other connected external hardware interfering with the boot process.
Repair Steps & Checklist
