I just received and installed this drive a few days ago, installed, and upgraded to SB02. I have the exact same problem - the drive inconsistently reads all burned media. It will read all factory stamped media. Prior to this drive, I had another burner that consistently produced good quality DVD-R’s on some cheap meritline media. These dvd-R’s are readable in all of my home DVD players. However, the Samsung drive refuses to read them. It also refuses to read an old DVD-RW and a recent DVD+R burn (the second being on fairly decent media). I get errors like “Timeout on Logical Unit”, “Power Calibration Error”, and “Invalid code in CDB” from Nero CD-DVD Speed and nero burn logs during validation. Ironically, Nero tells me it burns to that media just fine (except it can’t read it). The burns are barely readable in my home DVD players.
The prior drive I mentioned failed a burn in the middle and I just assumed that the drive died. But could this actually be a power supply or Windows XP related failure? Or is there something wrong with the SB02 firmware for this drive? I’m at wits end… Can I downgrade the firmware?
thanks for any and all help!
