I am a fan of Plextor (or rather have been) and bought a 716A. Today the second device in 60 days died. The first one stopped burning with an error message and did not recognize any other DVD or CD-ROM afterward. Today it burned a -RW, ejected it after finishing the burning process and did not recognize any DVD thereafter. In the first few minutes after I noticed it, the 716A still worked with CD-ROMs. About 15 minutes later it went completely dead. Now it does not accept any CD-ROM or DVD. After seeking a few seconds the LED is signaling something like blink blink pause blink blink pause blink blink ... (Auto adjustment failed - I think).
Since I bought both devices at Amazon, I hope they are going to refund me once again. Well, I gave Plextor one last chance and ordered a new 716. But my question is: Could I have done anything that triggered these defects? I mean I have just put the 716 in my PC, connected all cables, flashed the newest firmware and used the burner. I always use a single -RW from TDK (for backups).
