Does this drive support multiple reading from the same disc? I don't know the exact technical term or if the term I described is right or not, but here is the problem:
I was copying a DVD to my hard disk when I tried to copy another thing from the same drive at the same time. (i.e. having 2 copy processes at the same time) I know that this is wrong. Previously when I did this on my old drives, the copying will take a lot of time but it will finish. What happened was that the second copying process didn't start (I got the window, put no progress) and the first one stopped (again, the window is shown but the progress stopped). I told myself that this was wrong and didn't try it again.
A few weeks ago, I downloaded a Linux distro (Ubuntu Live CD). When I tried to boot it from the BenQ drive, it gave me a read error and the loading stopped. I tried this disc on many drives (including writers) on the same PC and on my other PC and it worked perfectly. So, my guess is that it did the same thing I did before, tried to make a multiple copying process.
Is this thing common with DVD burners or with BenQ drives? Or is it a faulty drive? I am 100% sure that the Linux disc is ok. Tell me what you think please.
Thanks for reading this long message.
Well, I can honestly say it's been at least a VERY long time since I've tried to copy multiple things off of a CD/DVD from 2 different windows. As I recall, it "worked" but it was much slower then doing one and then the other. I haven't tried specifically doing this on a BenQ drive however. I *AM* fairly sure that no OS installation would be trying to do multiple copy processes from the same disc though... it wouldn't make any sense.
Ok, I took a pause writing this, and I'm currently copying two processes from the same disc, using my DW1640. It took about 3-4 minutes for the second process to even LOOK like it was copying though, and both processes are showing more then 100 minutes remaining, when individually they should both be around 6min (which is what the first one started at).
So the BenQ DW1640 *CAN* handle this... although it's not recommended. Maybe you gave up on the double copying too quickly?
As for why the Linux disc won't install... I have no idea. But I don't think it's related to double copying. Even if the disc is fine, maybe try making another copy of it? Or maybe burn it to a DVD instead (if it's currently a CD), if that'll still work.
