| Symptom | Likely Cause | Solution | |---------|--------------|----------| | BSOD 0x0000007B after changing mode | OS driver mismatch | Revert to original mode, or repair OS boot | | SSD slow (≤ 150 MB/s) | Stuck in IDE mode | Switch to AHCI (may require OS reinstall) | | RAID array not detected | Wrong mode (AHCI instead of RAID) | Change to RAID mode and recreate array (⚠️ data loss risk) | | Hot‑plug drive not recognized | SATA port not set to hot‑plug capable | Enable “Hot Plug” per port (separate setting) |
