Tee Hee, I thought I was going to have the same issue myself, I have the OCZ Agility 3 running 2.11 and on saturday night I had left computer on to DL a large file, on Sunday I seen it was hanging on windows boot asking to insert media and press a button to continue....
Few reboots later and still not showing in BIOS or post so I let it sit for 20 mins and cold booted and it went straight to windows first time.
This is the first issue I've had with the drive in 3 months so I'd suggest possibly installing 2.13 (as I will do this evening) and see if that helps at all, providing you can find it on BIOS first, if not RMA the face off it
