I have a Liteon Ltr-121032 cdrw drive, and during the flashing of the firmware, my pc hung, and after reboot, my pc could not find the drive at the startup, so could you please give me some advices of how to make it work again? or i need to have it repaired? thanks a lot!!!!

I think it's gone.

I have the same problem, and I have called the customer service department of Liteon's distributor in TW, they told me this drive maybe broken, and asked me to send back to them to repair! Poor us...........
