I have a big problem with my two BenQ drives, a 1620 and a 1640 in different pcs: Trying to burn images with Alcohol 120% fails most of the times, i.e. in 6 of 10 tries with a recording error at around 70% of the image - tried with different media, different images (all about 700MegBytes), especially when selecting low write speeds such as 12x or 16x, but sometimes also at higher speeds.
The same images work flawlessly on an LG 4120B in an external case in attached to both computers, no problem with the LG, but both BenQs horribly fail.
The 1640 already is a replacement because its predecessor had the same problems, first I thought the new drive was better but it isn’t.
Question now, dows the Benq have a general problem writing to CDs? All the DVDs tried work absolutely perfect, only CDs make a lot of trouble here.
