I stopped using my I/O magic benq 1670 after I got a benq1655 from newegg about two months back. When I started using the 1670 recently, I noticed that the burns are EXTREMELY slow…I’m talking over TWO HOURS to burn and verify a regular SL dvd.
What I have tried:
Checked to see if DMA is enabled. It looks like it is enabled…but I do have a concern. Under one of the primary channels, device 1 is selected as “DMA if available” but the current transfer mode shows “PIO mode” and it won’t let me change it. However, it doesn’t show this in the other primary channel. Sorry, I don’t quite understand this–I hope I’m making sense. I have included screenshots below.
Tried burning using different burning software. Tried Nero Burning Rom 6 and ImgBurn. No difference in result.
Upgrading to the newest 1.02 firmware (did this using MCSE, then upgraded using new 1.02 firmware, converting the I/O magic drive into a “real” benq 1670). RESULT: still took over two hours! Posted below is a log from a recent burn using Nero Burning Rom 6, Verbatim MCC002 burnt at 8x).
I hope I have given you all enough information to help me figure out what is wrong with this burner.
