How can I reset an Acopos 4007 drive when it's displaying an error?

The reset procedure varies depending on the error. A soft reset (power cycle) is often the first step: Turn off the power to the drive and the MCU for a few minutes, then turn them back on. If the error persists, a hard reset might be required. This usually involves a specific button combination on the drive (consult the Acopos 4007 manual for the exact procedure – it often involves holding a reset button while powering on). However, a hard reset may result in data loss, so it should be used as a last resort.
