DVD writer instructions for rincon users
========================================

General:
--------
The DVD is scsi device 0,1,0, which you'll need to know
for using the burning software, dvdrecord.

The DVD can be mounted via:
	mount /mnt/dvd

I've made a generally writeable scratch directory you can use
for the iso image files:
	/data2/DVD

Feel free to borrow the DVD for burning any time. 

Reading a DVD, e.g. for copying, really slows the machine down.
Please coordinate with me if you need to do that, even if I'm 
out of town, as I and several others use rincon a lot.

Please be conscious of disk space.


To create an iso image for burning: 
-----------------------------------
mkisofs -R -o image.iso /path/to/data

image.iso is whatever name you want to call the temp
file of your data.  Everything under /path/to/data/ will 
be packed into the iso image.  For example, if I have a 
directory MIPS0000500/ with many subdirectories that I 
want to burn I type: 

mkisofs -R -o mips400.iso ./MIPS0000400

If you want to check the iso image to verify it was properly
created

mount mips400.iso -r -t iso9660 -o loop /mnt/tmp

where /mnt/tmp is an existing mountpoint.  You can then 
browse through the directory as you normally would.

To write the DVD:
-----------------
sudo is a wrapper that allows you to run dvdrecord without
needing the root password. Use it and dvdrecord as follows:

sudo dvdrecord -v -dao dev=0,1,0 mips400.iso

You can drop -v if you want (just verbose output).  You 
can also do it all as one step: 

mkisofs -R ./MIPS0000400 | sudo dvdrecord -v -dao dev=0,1,0 -

Mount the dvd after you've written it (/mnt/dvd) and do an
ls on it to make sure it is OK.  umount it before ejecting.


To Erase a DVD-RW: 
------------------
sudo dvdrecord dev=0,1,0 blank=fast

In general blank=fast will work fine. If you really want
to get rid of the data on the dvd, substitute the much slower
option "all" for "fast".
