Re: No supported write modes with LG GSA-H62N SATA DVD+RW
For what it is worth I have the following to add to all the discussion.
I have a pioneer 212 (sata) DVD which I have tried on two computers an ECS
KV2 Lite +Dualcore 3800 and an MSI K8T Neo +Turion MT32 both running Fedora
7.
Neither cdrecord nor growisofs work on CD, DVD-R nor DVD+R (various errors)
WIN XP works, but only if DMA is disabled for the drive. I get about 2.5x
write speed with the 3800+.
Both machines have a VIA VT6420 Raid controller (in ide mode)
I tried my burner on a friends machine with nvidia sata controller and
everything worked fine. (I bought the 212 because he had several on several
machines and they worked fine)
It apeared that when writing (which succeded on dvd+r - just incorrect data
and occasionaly some data was written onto a CD) that the data was prepended
by 32 bytes every 32K on the DVD-r and some smaller number (i now forget) on
a CD
00000000 2a 00 00 00 00 00 00 00 10 00 00 00 00 00 00 00
|*...............|
00000010 00 23 05 40 00 00 00 10 00 23 05 40 00 00 00 10

etc.
The 32 bytes of data at the end were lost. This was not entirely consistant
and occassioanly a full buffer was written correctly.
It looks like I eill need to get a PATA burner!
