Re: dvd burning problem, dvd+rw-tools, LG GSA-4120B
READ TRACK INFORMATION[#1]:
Track State: invisible incremental
Track Start Address: 0*2KB
Next Writable Address: 0*2KB
In DVD+R case the last line would mean that it's OK to write.
So the disc is not (yet) a coaster after all, eh?
Note that I wrote "*would* mean." Meaning that I wanted to say that
there is a *remote* possibilty that "the disc is not (yet) a coaster,"
but not "atfer all":-)
Try another media brand. Also try to lower the recording speed. Being
rather bizarre, the problem smells poor firmware media support for
particular brand or media product. A.
OK, this is wierd, I tried -speed=6 and -speed=4 but
growisofs kept saying the "Current Write Speed is 8.2x".
# growisofs -speed=4 -dvd-compat -Z /dev/hdc=/tmp/tj1-60.iso
Executing 'builtin_dd if=/tmp/tj1-60.iso of=/dev/hdc obs=32k seek=0'
/dev/hdc: "Current Write Speed" is 8.2x1385KBps.
This is weird... According to dvd+rw-mediainfo your unit offers 4x and
8x, so that -speed=4 should result on 4x, not 8x. But wait a minute! The
code pulls the speed list from unit and simply assumes that lowest
velocty is 1x, while in your case it's actually 4x. OK, it's time to
reconsider this for next update, but as of now -speed=1 and -speed=2 are
those which are mapped to 4x and 8x for your unit. Yes, it's somewhat
confusing, and it will be fixed. Till then just bear with downscaled
-speed arguments.
# growisofs -speed=1 -dvd-compat -Z /dev/hdc=/tmp/tj1-60.iso
Executing 'builtin_dd if=/tmp/tj1-60.iso of=/dev/hdc obs=32k seek=0'
/dev/hdc: "Current Write Speed" is 4.1x1385KBps.
... and so on until ...

:-[ WRITE@LBA=1a30a0h failed with SK=4h/ASC=09h/ACQ=01h]: Input/output error
4/09/01 stands for "TRACKING SERVO FAILURE" (see
http://fy.chalmers.se/~appro/linux/DVD+RW/keys.txt) and means that
tracking circuitry has hard time following pre-groove spiral. This
indicates either poor media or poor media support in firmware or simply
deficient hadrware [in which case you should ask your vendor for
replacement].
Different SK error code now: 04/09/01. I could mount the disc, and see
the list of files, but the files are not readable.
You should be able to read some files, those which physically residing
on media prior point of failure. The fact that you can list files
confirms this as directory structures are collected in the beginning of
the media. A.
