Actually cdrecord is now included in Solaris 10 Update 2 but one must be root
to use it.
Here is a comparison of the two tools that I use :
With cdrw I can burn almost anything. Almost. I do not need to be root
to use it and I don't need any special libraries ( libscg ) however, it is a
tad simple and can fail at times :
[ scan for devices ]
bash-3.1$ cdrw -l -v
Looking for CD devices...
Node Connected Device Device type
----------------------+--------------------------------+-----------------
cdrom0 | SONY DVD RW DRU-820A 1.0b | CD Reader/Writer
cdrom1 | PIONEER DVD-RW DVR-107D 1.21 | CD Reader/Writer
[ examine the media in the SONY device ]
bash-3.1$ cdrw -v -M -d cdrom0

[ blank that media ]
bash-3.1$ cdrw -v -d cdrom0 -b all

Blanking the media (Can take several minutes)...done.
[ examine it again ]
bash-3.1$ cdrw -v -M -d cdrom0
Device : SONY DVD RW DRU-820A
Firmware : Rev. 1.0b ( Feb07 ,2006)
Media is blank
[ try to burn CD1 from SUSE Enterprise Linux 10 ]
bash-3.1$ cdrw -v -d cdrom0 -i ./SLES-10-CD-x86_64-RC3-CD1.iso
Initializing device...done.
Size required (709224448 bytes) is greater than available space (681986048
bytes).
So that fails. Possibly for good reason.
Now then, a look at cdrecord. As the root user only <--- !!!
What version of cdrecord ?

You can see that cdrecord seems to find everything on every bus but does
not see the tape drive for some reason.
# mt -f /dev/rmt/0lbn status
DLT4000 tape drive:
sense key(0x6)= Unit Attention residual= 0 retries= 0
file no= 0 block no= 0
# ls -lap /dev/rmt/0lbn
lrwxrwxrwx 1 root root 61 Jun 30 10:17 /dev/rmt/0lbn ->
../../devices/pci at 0,0/pci1011,24 at 11/pci1000,1000 at 4/st at 4,0:lbn
#
Not that we care about the tape drive, it just seems odd that cdrecord can
detect every SCSI bus and every disk on every SCSI bus but does not report
SCSI tape devices as being present. Interesting.
Now then .. let's just inquire about that SONY device :

Now LOOK at all that information ! There you see the cdrecord will drag
into every nook and corner and tell you everything you ever wanted to know
but were afraid to ask :-)
Here is what I see right away :
The device details in mixed English :

What media is in this thing right now ?

And a real big question, what can this SONY drive handle ?

That's a pile of information and it gets even better :

So essentially cdrecord scans the bus and tells me about every SCSI disk and
every ATAPI CDROM/DVD drive. It also tells me more than I want to know
about the SONY unit, the driver, the options supported, the media size and
speed and the manufacturer. Well done Jörg Schilling !!

Well golly gee. Looks like cdrecord just moves along at high speed and
has no problems with that ISO image.
How do I know that its really any good though ?
There is a tool called readcd that does a nice job of reading the ISO image
from the drive and dumps it into a file for us.
Thus we can verify the burn was absolutely accurate :
# which readcd
/root/schily/bin/readcd
# readcd -v -dev=0,0,0 meshpoints=20 \

The answer is a resounding yes.
So what is the deal with cdrw ?
Everything that I have done is with snv_38 on a dual Pentium 400MHz that
I have been using for years. Its a solid machine.
# uname -a
SunOS titan 5.11 snv_38 i86pc i386 i86pc
I took a look at cdrw for the first time in years and was happily
surprised to see that I seem to be able to write and blank all of
the following :
(1) DVD-RW 80mm [ 2.8 GB dual sided for SONY HandyCam ]
(2) DVD-RW 120mm
(3) DVD-RW 80mm 1.4GB single sided Verbatim
(4) DVD-R 80mm
(5) DVD-R 120mm
The concept of "blanking" means nothing with the following but they write
just fine :
(5) DVD+R 120mm
(6) DVD+RW 120mm
I do not know what I can do with this yet :
(6) DVD+R DL this is the 8.5GB media
The issue here is that sometimes, for rare circumstances I am sure, cdrw
will fail to burn or fail to create an accurate burn while cdrecord just
works.
I can not report anything positive about DVD+R/DL yet .
