I accidentally pulled my external enclosure off my desk thanks to the incredibly long 1 foot USB cable. Now my WD 200 GB Caviar drive beeps twice at me, waits 5 seconds, then beeps twice again, and just keeps going. I assume this is a bad thing, but does anyone know what it means? It ran perfectly until this happened.
Your drive may have a seized spindle motor, or a stiction fault. Stiction occurs when the heads land on a smooth section of the platters instead of their normal landing zone.
