Hello,
After making two coasters with a graphical CD burning program using Ubuntu, I
decided to try using FreeBSD: I want to start backing up to DVD anyway.
After some searching I learned I missed some details in the handbook on the
first and second reads such as:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/creating-dvds.html
"The program growisofs(1) will be used to perform DVD recording. This command is
part of the dvd+rw-tools utilities (sysutils/dvd+rw-tools). The dvd+rw-tools support all
DVD media types."
I had hard time finding the non-existent growisofs package!
"These tools use the SCSI subsystem to access to the devices, therefore the
ATAPI/CAM support must be added to your kernel. If your burner uses the USB interface
this addition is useless, and you should read the Section 18.5 for more details on USB
devices configuration."
Using the atapicd driver generated the following error message:
:-( unable to CAMGETPASSTHRU for /dev/acd0: Inappropriate ioctl for device
After the command:
$ growisofs -dvd-compat -Z /dev/acd0=8.0-RELEASE-i386-dvd1.iso
before you ask:
MD5 (8.0-RELEASE-i386-dvd1.iso) = 5336cd827991e4d4cff6d73c4a5ca105
Release announcement: 5336cd827991e4d4cff6d73c4a5ca105
I tried playing with /etc/devfs.conf as suggested by Predrag Punosevac
$ id
uid=1002(backup) gid=1002(backup) groups=1002(backup),5(operator),1003(Share)
$ cat /etc/devfs.conf |sed 's/#.*//g'
link cd0 cdrom
link cd0 dvd
link cd0 rdvd
own cdrom root:operator
own dvd root:operator
own rdvd root:operator
perm cd0 0660
perm cdrom 0660
perm dvd 0660
perm rdvd 0660
perm xpt0 0660
perm pass0 0660
-> that sed command was stolen from a script expecting <CR><lf>
->originally used device acd0 (until enabling atapicam)
$ cat /boot/loader.conf
acpi_load="no"
apm_load="yes"
atapicam_load="yes"
#ata_load="yes" # enabled by default
scbus_load="yes"
cd_load="yes"
pass_load="yes"
atapicd_load="no"
#hw.ata.atapi_dma="1" # enabled by default
With the atapicam driver I was able to somehow get growisofs to go through the
motions of burning the DVD, even have a kernel message from GEOM reading the
BSD label:
$ tail /var/log/messages
Dec 3 20:00:00 dusty newsyslog[833]: logfile turned over due to size>100K
Dec 3 20:00:28 dusty kernel: GEOM_LABEL: Label for provider acd0t01 is
iso9660/FreeBSD_Install.
but can't read the disk to verify it:
$ dd if=/dev/cd0 bs=2048 | md5
996592+0 records in
996592+0 records out
2041020416 bytes transferred in 1292.388284 secs (1579263 bytes/sec)
19b087536234b316b64232ba6b1c1799
Umm. Nevermind. I added the block size so nobody would try suggesting it has an
effect :P previous error:
$ dd if=/dev/cd0 | md5
dd: /dev/cd0: Invalid argument
0+0 records in
0+0 records out
0 bytes transferred in 0.000721 secs (0 bytes/sec)
d41d8cd98f00b204e9800998ecf8427e
I noticed that the hash does not match the ISO file. Is that normal for DVDs?
For CD images I often get the md5 hash to match.
The man page for atapicam(4) warns:
"atapicam and ATAPI-specific target drivers (acd(4), ast(4), and afd(4))
can be configured in the same kernel. Simultaneous access to the same
device through the SCSI generic drivers and the ATAPI-specific drivers
may cause problems and is strongly discouraged."
Is there anything special I should do to try to disable the atapicd driver? I don't think
my 'atapicd_load="no"' line in /boot/loader.conf has much of an effect.
Regards,
James Phillips

Aloha JP,
This is what I use on FreeBSD from the command line to burn DVD's.
I have used it on FreeBSD 8* for a while. (Simple and it works.)-

dvdburner.doc
DVD+R burner Setup and operation
From sysutils/dvd+rw-tools
Intall the DVD port
# growisofs
( used the following from all the suggestions and it worked with Manolis
DVD p1 7.2)
1st> Put hw.ata.atapi_dma="1" in the /boot/loader.conf
2nd> Put apticam_load="YES" in the /boot/loader.conf
(That 2nd 18.7.2 instruction is not clear in the Handbook section and
should be added.)
Then> Run # growisofs -dvd-compat -Z
dev/cd0=/usr/home/alp/FreeBSD_7/7.2-RELEASE-p1-i386-disc1.iso
(all on one line)
Then> Use cd0 as a DVD burner and make the DVD-R
I tested the DVD on a spare box and it installed just fine.
