Unknown Drive Rating

What does InF1 mean?

The drive has detected an unknown drive rating. This implies a critical internal inconsistency where the drive cannot identify its own power or voltage characteristics, preventing safe and proper operation. This usually points to an internal hardware issue.

• The drive's power rating is not recognized or is outside the supported range.
• Incorrect model number selected in configuration parameters (e.g., P1-01).
• Incompatible firmware flashed to the drive.
• Physical damage to the drive's rating identification components.
