| Problem | Likely Cause | Solution | |---------|--------------|----------| | "Firmware mismatch error" | Wrong hardware revision | Double-check product SKU. Rr52c.03a may only work on Rev C boards. | | Device stuck in boot loop | Corrupted flash due to power glitch | Force recovery mode (usually shorting two test points or holding reset button for 30 seconds). Re-flash using serial console. | | Performance dropped after update | Configuration reset to conservative defaults | Reapply your tuned settings: queue depth, NCQ, power management policies. | | Drives missing from RAID | TLER values changed | Use the management utility to re-import foreign configuration or rebuild array. |
