This is my first post in those forums. I’m a spanish guy who have a problem. I have not been able to solve it by myself, posting on my usual spanish hardware forums or deep searching google.
I’m sorry if my expression is not as good as it should be, but english is not my first language and I have only a medium level.
Which no more introductions, I tell my problem to all you:
More than one year ago I bought two identical benq dvd writers, in order to be able to write 2 DVDs at the time (2 identical DVD, the same image/content).
Then I found that writing with one writer was perfect, taking around 9 minutes at 8x and 6 at 16x (normal times).
The problem was when I selectec in nero the option “write with multiple recorders” and tried to make 2 copies of the same compilation/image. Then, the speed recording fall down to 2-3x even when I setted the writing speed at 8 or 16x.
Recording time went up to more than 20 minutes, making in this way stupid the fact of writing with que 2 writers (it takes more than double time). I noticed it happened with nero and alcohol 120.
After many test and headaches I found a solution: Formatting and reinstalling windows AND, and this was the key, not to install IDE drivers for my board (nvidia nforce 4 chipset).
So, I thougth I had found the source of the problem, and writing with 2 writers went perfect and fast at 8 or 16x.
It happened over one year ago.
Last week, I decided I had to format my drives and write everything on DVD. I found that for dual burnings (normal burnings with one writer was perfectly) the speed was ok, but using nero, at the end of the write nero hangs and the 2 dvd have to go directly to the recycle bin (the real, not the windows one :P). In the other hand, alcohol works perfectly with dual writings, so i used it for this task.
Today, I have format and reinstall windows (2 times, not one) and again, nero and alcohol falls to 2x - 3x when using the 2 toasters at time, and this time I have not install nvidia IDE drivers, so I’m desolated becouse I don’t know the real source of the problem
My computer is:
X2 3800+ @ 2,66 ghz
2gb ram DDR1 533 (2x1gb)
2xWD SATA2 16mb cache in raid 0 (2x250gb)
1xWS SATA1 8mb cache (200 Gb)
Mainboard: DFI Lanparty SLI-DR nvidia nforce 4 chipset
2xBenq DVD writers 16x DD DW1640 Connected one to primary IDE and other to secondary IDE (both as masters).
Windows XP SP2
Things I think can be discarted:
-Overclocking: I’ve write correctly with overclock, so it don’t seems to be cause.
-Writers firmware: I upgraded both writers to last version when bought them and found the problem. In addiction, I tried 2 LG writers obtaining the same speed problem when using 2 ones at same time.
-Media: I use verbatim DVDs. I insist when using only one writers goes perfect, and more important, I’ve write them ok yesterday with alcohol before formatting.
So, it’s the problem, i thank everyone for taking time to read and i keep the hope to find the real source of the problem.
