I just join the plextor family with a PX-716A TLA #0202. I have copied an audio CD with Exact Audio Copy(EAC) when I first installed the drive. My system crash down and I have to reinstall the Windows XP(SP 2). I have also upgraded the firmware to V1.03 (RPC 1 from tdb). After that I found problems in EAC. When I detect the drive write features, I found that 716 burnt for several seconds and LED turns green. The screen indicated it proceed for serveral percent only. Then I have to wait for several minutes and return to the original screens. It seems that the process is completed (I believed not). When I burn CD, it burnts for a few percent and it stops with error "Logical unit not ready, long write in progress!" I have no ideas of what's happening. I tried serveral times and still the same. I have also tried to flash the firmware to V1.03 (original RPC 2 from Plextor) or V1.02, downgrade Plextools to 2.17 or even not start Plextools. Problem still existed. I suspect any software collided with EAC. I have also tried to reinstall the Windows XP and just installl EAC and Plextools but no improvements at all. Can anybody tell me what's happening to my drive? Thank you.
