growisofs DVD unreadable on ThinkPad
Hi, newbie user here ...
Trying to copy my RedHat 9 installation DVD:
dd if=/dev/cdrom of=rh9dvd.iso
growisofs -dvd-compat -Z /dev/scd0=rh9dvd.iso
(using dvd+rw-tools-5.19-1.4.9.7.tar.gz)
growisofs seems to complete properly. At the beginning, a few lines seem to indicate
"zero" progress, but then it settle into 2.3x speed and continues there until completion.
The resulting DVD IS readable on the source/creation drive, but is unreadable on
my IBM ThinkPad CD/DVD drive (the original RedHat DVD IS readable on the
ThinkPad). Orginally, I had this problem with a Plextor 708A; thinking the Plextor
might be the problem, I replaced it with a NEC 2500A but have the same problem :)
I am using FujiFilm DVD+R media. I realize that this may be a media problem,
but I am concerned that I am burning unreadable DVDs without any warning ...
I have some additional DVD+R media on order that should arrive shortly.
I also tried "-speed=1", but growisofs seems to run at 2.3x speed anyway.
My "mediainfo" appears below. Thanks, Scott. (not subscribed to list)
