PSP reading UMDs is correct behavior. The UMD drive *should* spin up and show the game icon on XMB. If it's not working, here's the diagnostic:
| Symptom | Likely Cause | Fix |
|---|---|---|
| Disc icon doesn't appear | Dirty laser lens | Clean with 99% IPA + microfiber on cotton swab. Gentle circular motion. |
| "Cannot read disc" error | Scratched UMD / dead laser | Toothpaste polish (light scratches). Laser replacement ($15-25, requires disassembly). |
| Loud grinding/clicking | Spindle motor / laser sled | Lubricate sled rails (white lithium grease). Replace drive unit ($30). |
| Ejects immediately | UMD sensor / latch broken | Check plastic tabs on UMD case. Tape shim on sensor. |
