Does the HP Writter 640c Supports 8x DVD+R DL?

HI, I’m currently having trouble writing an image to a Memorex DVD+R DL (I know cheap media). Along time ago I was able to do it, but I notice the old disc were 2.4x DVD+R DL, this new one are 8x DVD+R DL. I’m not sure if there is a difference. I update my firmware just in case to version QS12, I think it’s the latest one… I hope someone can help me, thank in advance.

By the way, I’m using ImgBurn, here is what the logs says:

Although I don’t know exactly which media this drive supports, I don’t think the question should be if it supports 8x DL media in general, but if it supports the one you have. The only dual layer media that is known to be reliable and compatible with most burners is Verbatims, especially those made in Singapore (a lot of people seem to have success with Falcon, though the jury is still out on that one).
Memowrecks is known for selling low quality media. Also, there is no guarantee that the 8X media you have now is even made by the same company as the 2.4X media you used to have (or, for that matter, the disks you might get if you’d get another box of them now (which I obviously don’t recommend)).

Get mkm001, your best bet.
