NEC ND-3520A - Speed issues in cdrecord-prodvd and growisofs
Hi all,
I recently picked up a NEC ND-3520A and I am having speed problems with this
drive under linux. A quick "just to make sure" test in WinXP shows that these
errors are indeed specific to cdrecord-prodvd and growisofs.
The media I am using MID is "PRODISC/R03" and I can burn this media perfectly
in WinXP using Nero at 4/6/8/12x. Under linux, however, I see a few different
things:
Regarding cdrecord-prodvd, this drive shows up as only being able to write at
6x max. I am using the latest release of this software, and at the bottom of
this post is a -prcap output.
Regarding growisofs, dvd+rw-mediainfo shows that in Speed Descriptor #0-3 that
this media indeed can be burned at 4/6/8/12x, however oddly enough under "GET
[CURRENT] CONFIGURATION:" the "Write Speed" descriptions only go up to 6x --
However, when growisofs is executed it WILL burn this media at 12x, but
unfortunately I wish to burn this media at 8x; specifying -speed=8 does
nothing but burn this media at 12x again. dvd+rw-mediainfo output is at the
bottom of this post.
I hope that with this info I can help get these two problems resolved with the
NEC ND-3520A burner. If you need more info or testing, I will be happy to
help.
