I can’t get my BenQ DW1620 w/ B7V9 (speedpatched) to burn any DVD-R media at higher than 16X! I can select it, but it ends up just burning it at 8X. I’ve heard of this problem before, but I don’t remember how to fix it.
External enclosure? 80 pin cable? DMA problem? MS drivers installed? Tried burning with another application?
New problem, did you burn at 16X before but not now?
How do you know it is 8X and what app. are you using to burn?
Well there is definatly something not right here! Just tried a Nero Create Data Disc with Maxell RG03 and CD Speed set to maximum write speed. So this disc should have written @12x but only wrote at 8x. I did check MID write speeds with CD speed before and after the burn and they don’t agree. Did a Create Data disc Here with same FW and it did burn @12x The only thing I have done different is updated to Nero 6.6.6.013. Not blaming Nero but could be this update has a glitch with B7V9 FW.
Well I backtracked and reflashed with stock B7V9 FW W/O speed patch, No Joy! Reflashed with MSCE increase read speed only, No Joy! Completely uninstalled Nero 6.6.6.013 including deleting Ahead folder from Program Files, rebooted and then did a fresh install of Nero 6.6.6.08A, included a Nero MID check after burn. Problem Fixed! Only cost me 4 disc’s to find out because a Qsuite simulated burn would go to 12x but would only do a real burn @ 8x.
@RangeRoad Sorry about interrupting your thread as I thought the problem was related. Guess not.
Well this problem still exist and a new FW hasn’t arrived so I will add some more info.
Today Flashed both 1620’s on Primary Master (Safe Mode) to B7L9 then shut down twice, flashed to B7T9 shutdown and then to B7V9 shutdown. Flash was done on My S ATA drive hooked to (Intel Controller). Then I inserted a TYG02 Disc and checked it in both drives with DVD Identifier and every thing looked good all descriptors were there. Booted to one of my other HDD (Same Windoze) hooked up to my Promise 378 S ATA Controller (IDE Mode) and checked the same thing. The result is posted below. I am not sure if the controller has any thing to do with it and it may be Windoze or registry, but if the media is not being identified properly that could be the cause of the strange write speed problem. Hope this helps someone or someone can offer a an educated guess.
It’s three months since my last attempts to burn TYG02 at 12x…
Today I wasted another 2 discs while trying to get it working.
crossg, I don’t think DVDIdentifier will lead us in right direction. As you can see in attachment, all my drives fail to display available burn speed information on TYG02 (and the same goes for MCC 03RG20, ProdiscF01…)
Clearly a bug, even in latest DVDIdentifier.
Yep I agree with you but maybe some of this info will help them figure it out and we can get a good working up to date FW for the 1620. If not we always have ala42’s MSCE and Quikee’s WOPC Tool. With this FW I have probably wasted 20 or 30 good disc’s.
