[qanda]This thread is about the Optiarc AD-7203S. Click here to see full specs[/qanda]Ok. recently bought a Gateway computer that has the Optiarc 7203S drive. I have Windows Vista Home 64 bit edition with Nero 9.0, Ashampoo Burning Studio 8, and Alcohol 120%. My device manager tells me the drive is connected va SCSI connection. After researching the capabilities of this drive, I download some HD movies that I have in .iso format. I went out and bought the Memorex DVD+R DL media to burn these. The system does not recognize the disc, although it has burned single-layer DVD-R media without a problem, through all 3 programs. I downloaded the 1.06 firmware update, but get the Target not recognized error. I gownloaded the modified Dee’s firmware update, but it’s a bin file and I cannot mount the image or otherwise extract it, and there were no other instructions. All programs and Sony’s specs page show that this drive accepts DVD+R DL and DVD-R DL media. Please help!?!
