Thanks guys for you input
Was 1x and 2x burning checked in MCSE before ? The firmware might not have a writing strategy for those speeds, so check your burns with kprobe or cdspeeds.
In case these low speeds were available in MCSE before, which burning software did you use ? If you select 1x,2x,4x, does your burning software allow 1x and 2x burning ?
I don't know what you mean by "strategy". I simply loaded MCSE, loaded Sony710A firmware file, than added my media label since it wasn't there (something infodisc..). I loaded it via DVD identifier, as was explained in help file, than near to my media's name there were only 4x 6x and 8x speeds checked - same ones i saw in Nero before. I unchecked them , and checked 1x and 2x instead, than saved the patched firmware and reflashed the drive. Then sucessfully wrote disks at 2x (i suppose 1x would work too, didn't try.)
Have you checked that UDMA2 is enabled on you drive ?
Can you burn your CD-R without speed reduction when the data is coming from the network ?
How fast can you copy your network based source file to your local harddisk ?
Did you burn large image files or many small files when you got problems @4x write speed ?
Does burning @4x work from the local hard disk ?
The network drive is 2xScsi 36gb disks, network drive is very fast, when copying a 700mb file from network to lacal hdd - it takes 2minutes. In all numerous previous cases, when writing failed- there was little disk activity, and very low cpu usage, and full buffer. Before that i have these problems:
1) Nero just stuck on some percentage (say, 18%) and wouldn't move on for hours, i even couldn't close it unless i used end task.
2) I was getting "writing failed" somhere in the middle of writing
3) most of all - i have failures at the very end, when it wrote "writing lead out"
I also tried some 5-6 types of various media, since i thought that it is media was faulty.
Good job on seeking out ala42's excellent MCSE tool and finding a solution to your problem! Thanks also for sharing your solution as it may help others .
You can check your burn results with Kprobe 2.4.2 BLER scans(scanned at 4x scan speed the forum standard for comparison ). You can read Interpreting PI/PO error scans to find out what these graphs mean . PI/PO is now referred to as PI/PIF. Roughly, PImax<280; PIFmax<4. Attaching disc quality scans to your post of any offending discs will help us help you .
Thanks for your suggestions. I run Kprobe2 and results was very good (pi~20,po~2)
This only confirms my suggestion that it's not faulty media problem
I'm surprised that media takes the addition of speeds lower than specified, any better than it takes the addition of higher speeds - as the "3S" chipset drives generally do not take simple speed editing.
Not sure what you mean - but my logical assumption was that it will not harm reducing the speed anyway, it might harm encreasing it. Isn't it right?
