Issues brining BD disks from the command line - write failures
First off I want to say thank all of you that work on this software that
makes it possible to do this stuff.
I'm more impressed than you can imagine.
Now that I have hopefully 'buttered you up' a little bit, I'm in need of
assistance, and I have exhausted my google skills in an attempt to find
an answer to the issue. At this point I'm trying trial and error, and
at $1.25 a disc, it's getting expensive.
A (large) part of my issue is me; I had this working at one point,
didn't write down _exactly_ all the requirements and process I followed,
and there have been quite a few kernel and program updates since it worked.
I am trying to backup large .wav files ( 1.3 - 2+GB in size) to BD-R media.
When I had it working, I would create a 25GB file with truncate, use
mkudffs to format the file as a filesystem, loopback mount it, and copy
data over to the file system, sync a couple of times, dismount and the
use cdrecord or growisofs (I have tried both) to burn the image to the
media.
I have two burners, on two different systems, so I know I'm pretty sure
I'm not having a hardware issue.
One is attached via a SAS controller via an eSATA breakout cable to an
external eSATA enclosure:
description: SCSI CD-ROM
product: BD-RE WH14NS40
vendor: HL-DT-ST
physical id: 0.0.0
bus info: scsi@4:0.0.0
logical name: /dev/cdrom1
logical name: /dev/cdrw1
logical name: /dev/dvd1
logical name: /dev/dvdrw1
logical name: /dev/sr1
version: 1.00
capabilities: removable audio
configuration: status=ready
*-medium
physical id: 0
logical name: /dev/cdrom1
The other burner is connected via internal onboard SATA controller:
description: DVD-RAM writer
product: BD-RE BH08LS20
vendor: HL-DT-ST
physical id: 0.1.0
bus info: scsi@2:0.1.0
logical name: /dev/cdrom1
logical name: /dev/cdrw1
logical name: /dev/dvd1
logical name: /dev/dvdrw1
logical name: /dev/sr0
version: 1.00
capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram
configuration: ansiversion=5 status=nodisc
I'm now _way_ behind on moving this stuff off to removable media and
I'm starting to get a bit desperate.
This last attempt, on the external burner using growisofs, new server
and fresh OS load is finally prompted me to annoy you with a plea for
help. This is as far as it got that time:
growisofs -speed=1 -Z /dev/sr1=/mnt/md9/bdburn/BDBurn.udf
Executing 'builtin_dd if=/mnt/md9/bdburn/BDBurn.udf of=/dev/sr1 obs=32k

Am I creating too large of a file to burn to the media - I note that
growisofs is saying "preformatting to 24.8 GB"?
This is the size I have used int he past that worked.
This is my actual UDF file size.
ls -al /mnt/md9/bdburn/BDBurn.udf
-rw-r--r-- 1 root root 25000000000 May 6 17:39 /mnt/md9/bdburn/BDBurn.udf
_any_ help in getting this sorted will be greatly appreciated.
