#13046 — 800/900MB CD burning problem. Help appreciated.

Hello all at comp.os.linux,

Firstly, I know there is a solution to the following as I have achieved
what I want before; but I have reformatted my system and having started
from scratch - I have completely forgotten how to do it.

The problem I have is:
I have at least one dvd-drive that I know can burn 800mb(90min) and
900mb(100min) CD-r discs successfully. I know this because I have
achieved this before on these drives, and all was good. If nothing else
I know I achieved this using K3b if not Brasero also, absolutely on the
same hardware. But now, as I have started from a fresh install - neither
application will allow me to burn more than a standard 700MB disc. I
allow overburn in the options - makes no difference.

I have looked into fstab stuff online, but I can't get this to work. I
suspect this is roughly how I got it to work last time, but I couldn't
be certain of that. I would be very grateful to anyone who can help me
get my show back-on-the-road burning 800MB and 900MB CDs.

I have been using Linux for years and am currently using Linux Mint -
but, I would admit that I mainly stick to web-server/client programming,
and LibreOffice, GIMP, Inkscape, etcetera - and I am a bit out of my
depth with fstab and such.

Thanks to all in advance, I would be very pleased and grateful for a
result on this one.

Ruaraidh

I can't give you the solution, not having burned an oversize CD in about a
decade or more.  but as someone that used to manage project archives for our
company, I feel like warning you: sooner or later, you'll be in a situation
where not only writing an overburn CD will be a problem. Reading one might
become a problem, too.

I hope someone gives you a solution to your problem, but if the written data
is important to you, you might want to consider limiting yourself to
standard volumes.

Question: Is there some reason to burn oversize CD-Rs and not just burn 
DVD-Rs?  I know that DVD-Rs are certainly cheap enough and DVD-ROMs are pretty 
much the standard optical drive.

Yep.

Trying to "overburn" is just (as they say) an accident waiting to happen

Hi there,

Thanks to all (Rikishi42, Robert Heller, Dan Espen) for getting back.
I've not looked at the newsgroup for a few days, sorry for the late
reply - kinda busy - I blame Christmas.

I take your arguments against over-burning on-board - I suppose it isn't
the safest thing. In fairness I could indeed use DVD-Rs for most things.

The only thing is; I have a bunch of 800MB and 900MB CD-Rs that I could
use, and I have found plenty of successful uses before - e.g. larger
SVCDs (no region), larger mp3-CDs, larger photo-CDs, things that work
with CD players where DVDs would not. Also it can make the difference
between 2 and 1 discs needed.

I will try again when I have time, and will post the solution in this
thread if I find it.

Thank you all for your effort!

Right and I have a few blank floppy disks kicking around.  But none of my 
currently running machine have floppy disk drives.  I also have a couple of 
blank 8mm video tapes, and although my Hi8 camcorder still mostly works, I 
will probably never use these blank 8mm video tapes.  Sometimes one has to 
draw a sort of line and discard old stuff (or repurpose it).

DVD's _are_ less reliable over time.
But I'd still write standard CD's, rather then overburned ones.

Seeking information: Do you have a citation to substantiate the
assertion, "DVD's _are_ less reliable over time."?

No, only my experience as someone who stared the company archives.
CDs were re-written every 5 years or so. The discs showed no defects,
but we replaced them anyway. For DVD's, we encoutered troubles even before 5
years. No everywhere, of course, but enought that we had to seek other
solutions.

Today I don't handle archives anymore. But mostly, files are stored in a
document handling system, and kept in an online database.
Good for some things, bad for others.

Are these CD-Rs and DVD-Rs or are they -RWs?

R only, I'd never use an RW for an archive. Less reliable quality, and an
overwriting accident is to easy.

You all might find the NIST study to be helpful 
<http://www.loc.gov/preservation/resources/rt/NIST_LC_OpticalDiscLongevi
ty.pdf>

It shows that of the 9 brands of CD-R they tested (with 90 samples of 
each brand), seven should last more than 45 years and two 30-45 years.

It also shows that of the DVD brands tested, 7 should last more than 45 
years, four 30-45 years, two 15-30 years, and two less than 15 years.

They also found that all DVD-RW tested should be good for more than 30 
years, about 2/3 of all DVD-R should be good for more than 45 (but the 
remaining thirs less than 30), about 80 percent of DVD+R good for more 
than 30, and about 2/3 of DVD+RW.

They don't, however, identify brands or chemistries other than to say 
that _all_ the CDs tested used pthalocyanine.

Note that the DVD+/-RWs don't as a group do much differently from the 
DVD+/-Rs.

I understand that the main issue with +/-RW media is that is *tends* to be 
writer-specific -- that is it reads fine *on the same device* as it was burned 
on, but that there are *sometimes* problems when reading them on a *different* 
device than the original burner device.  I *believe* that this is because the 
'burns' are not as deep (or whatever) as for +/-R media.

The significantly lower reflectivity of the RW media also plays a part
in this.  A "reader" drive that was not designed to operate at the very
low signal level of a RW disk has trouble reading RW media.  This is
pretty much any drive that was not designed to read RW disks from the
start.

Hmm, never heard of doing something like that.

Searches tell me that they sell 800MB CD-Rs.
I'd guess having one  would help.

Instructions for Nero say you must use DAO (Disk At Once).

Some people say you can damage the writer doing this.


I use CDs for music I play in the car.
I find putting MP3s on a data CD gives me space for about
700 tracks on one CD.
