Hi to everybody! I’ve searched for a couple of days every note that could solve my problem, but I didn’t find the solution… I have found many interesting suggestions, but… :
The problem :
BRAND NEW dvd rewriter LG GSA-4160B Fw A302 not burning faster than 8X and not recording Princo media.
AMD athlon 700, 393Mb Ram, 2HDDs 10Gb ATA66 UDMA both connected to MB Primary IDE.
LG GSA-4160B ATA 66 master on sec. IDE, LG DVD rom ATA33 slave on Sec. IDE.
OS Windows XP Professional (No Service pack2)
NERO Ultra Edition 126.96.36.199
Cd-dvd speed ver.4.08 and ver. 2.10.2
media used :
sony dvd +rw 2x-4x (2,30 Euros each)
tdk dvd -rw 2x-4x (2,30 Euros each)
princo dvd -r 1x-4x & 1x-8x (0,30 Euro each!!!)
imation dvd -r 1x-8x (1,30 Euros each)
traxdata dvd -r 1x-8x (0,80 Euros each)
verbatim dvd +r 16x (0,60 Euros each!)
what’s weird is :
rec time 4x (5540 kb/S) estimated time : 14 min, effective 14 min
rec time 8x (11080 kb/s) estimated time : 6 min, effective 8 min
rec time 16x (22160 Kb/s) estimated time : 4 min, effective 26 min
What I can see about Read Buffer and Drive Buffer is:
at recording speed 4x : they’re both always more than 98%
at recording speed 8x : Read Buffer from 50% to 100%, Drive buffer 98% or more
at recording speed 16x: both buffers continuosly bottom up
The DVD Burner firmware release was initially A302. With this release Princo media had no chance to be recorded… Nero advised recording completed with success, but the data (or videos) were unreadable. All other media were recorded and readed with success.
Upgrading Fw to A306 (yes! the cinese/japanese one!!) has modified the situation…:
Princo media are now well recorded and are well readable.(!!!)
rec time 16x estimated time : 4 min, effective 19 min, saving 7 min rec time!!!.
Nero never notified the change in speed, that means that seems to rec at 16x but it’s obviously not true…!
I’ve tried to :
0. defrag HDDs
- look for problems with dma access for HDDs and DVD but seems OK.
- check HDDs speed with Nero and they’re more than 12x, 21486 Kb/sec HDD1 & 20080 KB/sec HDD2.
- disconnect LG DVD rom slave on sec. IDE
- reinstall nero
- Create Test DVD with a Sony -Rw 4x media, and all seems ok.
- Test Verbatim 16x transfer rate, and resulted in average read speed 9x (isn’t it slow??), and I think this is not affected by HDD transfer data speed. May it be because it was a video dvd affected by riplock?
- Copy a dvd from HDD1 to the HDD2, timing about 15 min. (but I really don’t remember).
1- Ok if I have to rec at max 8x since I pay Verbatim only 0,60 Euro, but there is it really any problem with my LG GSA-4160B?
2- Is it there anybody experiencing real 16x rec on Verbatim 16x media with 4160B?
3- I may understand that for some reasons my pc is unfitted for 16x rec, 'cause of the HDDs (I’ve assembled it with garbage) but why is the rec time at 16x not only more than 8x, but even more than 4x? It could have been burning at 12x comparing transfer rates !!
4- May it be that trying to burn at 16x has bad impact on HDD performance so that the buffers can’t be correctly managed?
5- LG system requirements are greater than my Pc Hw… Does it really matters, since my CPU isn’t really busy when burning?
6- Is it there any outstanding dvd burner with low system requirements?
6- Should I upgrade my Via AMD chipset with other drivers than the microsoft XP ones?
-Fw A306 seems to have resolved Princo media compatibility with my GSA-4160 and it is probably true for other media too.
-By now I can burn at max speed 8x… not so bad.
-I don’t think useful to switch HDDs & DVD from primary to secondary IDE and viceversa…(??)
Next tries (not in order) :
- burn at 12x
- downgrade Fw to A303 (last LG official release)
- rec on Verbatim -r 16x
- rec / test on expensive media suggested by LG
- create dvd test media with Verbatim ±r 16x
- test my dvd burner on another Pc with better performing HDD and/or better Hw.
- change DVD recorder…!
Hoping I have been understandable enough, and that the steps I’ve followed to try solving my problem may help someone else.
Sorry if I won’t stay for a long time in forum but it’s getting late… I will for sure read any reply tomorrow…
Thank everybody for reading this and for any hardly wanted hint !!!
