i have a 1600 to 1620 benq drive, and i just lost some of my backups due to bad burns with 1620 b7t9/b7u9
i tried the same disk with 716a 1.04 & 3500a 2.19, and both produced very good results.
i was wondering whether my 1600 (now w/ 1620 firmware) is defective or could it be because it is not a true 1620 drive as i heard that the true 1620 has a different hardware from 1600
first one was burnt by 1600 with 1620 firmware b7u9 (latest as of 2005/03/21)
2nd one was by 716a 1.04
3rd one was by 3500a 2.19 rpc1/ripunlocked firmware
