Default Nero for Multisession discs: How much space is really left forfiles?

[email protected] wrote:

I'm using the bundled version of Nero version 5.5.10.9 to make multisession
discs. I see there is a graphical status bar at the bottom of the screen to tell
you how much total space you are using on the disc. It would help if I could get
a number that tells me exactly how much space is left for files when continuing
a multisession disc.

When continuing a 650 MB Multisession disc I clicked on the Disc Info icon and
it told me the available space was 61 MB. I then added 61 MB to the disc and
checked the File-Compilation Info screen.
This showed Total Data To Be Written: 61 MB. Then I checked the status bar at
the bottom of the screen and it and it was over the 650 MB line by what looked
like a lot. It showed the amount I was over by in yellow. Next I deleted a 5 MB
file from the disc. This put the status bar right on the 650 MB line.

What did I do wrong? Is there a better way to know how much space is left?


Burned 613M (compilation) on 656M disc. After the burn Disc_Info says
20M available. Compiled 20M data and the status bar showed yellow bar.
Click the Burn button and Nero went into analyzing disc. Nero then
prompted: "There is not enough space available to burn this compilation
unless the cd is finalized after burning. Do you want Nero to finalize
it after burning?" When selected No, Nero proceeded to burn
successfully! (20M data passed verification) Disc_Info says Total
capacity of 635M with available capacity greyed out.

Checked the cd with CD-R Diagnostic and it says the disc has passed all
checks for replication!

According to the above, go by the available capacity given by Disc_Info
and disregard the yellow bar.

Something's not quite right with available capacity, however.

656M(cd) - 613M(data) =43M
43M - 23M(first session overhead) =20M

So 20M avail cap is not after the second session overhead was accounted
for. Yet the burn was successful despite there was no room for the 14M
second session overhead.

I would have selected Yes to finalize since you would not be able to add another
session later in any case. I say more about this below.


Selected No to see what happens as Nero says no space unless finalize.
Well, Nero burned ok even if not finalized.

So 20M avail cap is not after the second session overhead was accounted

My impression is that 20MB available means after the second session overhead is
taken into account.


There are two "20M" here, the one I calculated and the one given by
Avail Cap. My calculated "20M" was arrived at without accounting for
the next session overhead.


As for the message, "There is not enough space available to burn this
compilation unless the cd is finalized after burning. Do you want Nero to
finalize it after burning?", that confuses me. I don't know why it seems to be
saying that if you finalize there will be enough space and if you do not
finalize there will not be. Doesn't finalizing use up some additional space?


Finalize does not use up additional space - and neither leaving it open
does, based on what I read. (The last lead-in is supposed to have a
close/open flag, and the address of the next track in the case of open.)


I think I get the same message even though I have the Finalize CD checkbox
checked on the Burn tab of the Info screen to indicate that I want it to be
finalized. So why is it asking me if I want to finalize? :-)

I even get this same message when I burn a DAO disc. I always click on Yes and
it burns but I don't know why this message is popping up.


That's weird, even comical. Didn't experience them as I usually leave
cd open and have about 50M spare room.

Avail Cap. My calculated "20M" was arrived at without accounting for
the next session overhead.


In other words because of the amount of data in the first session there should
have been 20MB left for both data and overhead of session 2. That's strange.


That's why I said 'Something's not quite right with available capacity'.

If the 20M by Avail Cap is after the overhead is accounted for, then I
shouldn't have got the not enough space message. If on the other hand
the 20M by Avail Cap did not account for the overhead, then don't know
where the space for the 14M overhead came from as the burn was
successful. Feel like going around a circle here.

Still I will go by the Avail Cap number and consider the number is after
the overhead is accounted for.

Since we know the amount of overhead, that leaves the amount of data in the
first or second session as being incorrect Hopefully this is a bug in the
version of Nero you are using that has been corrected. I'm going to start paying
attention to the amount of data written in sessions and see if I get the same
problem.

613
23 overhead
20
13 overhead
--------
669 is too much


The amount of data Nero reported is correct. I selected the data
amount. Nero and my figures differ by about 300K for what Nero calls
file system overhead in the Properties of compilation.

Read about the 1st session overhead:

file system overhead in the Properties of compilation.


Well now I'm confused again. :-)


(The 300K overhead is for the 2nd session. The overhead for the 1st
session was like 2M, IIRC.)

Want to get confused more? Burned 3 sessions. In the 3rd session, the
AvailCap was 10M, added 10M files. The compile Properties says the Total
data to burn is 13M. When click Burn, get the following:

Unfortunately your multisession CD is now full. The remaining free
space of 10M on this CD is insufficient to write your data of 13MB
and close the session, which requires an additional 14MB. Therefore
this multisession backup cannot be continued. Please start a new
multisession backup on a blank CD.

Deleted some files about 5M and the compilation Property says the Total
data to burn as 7M. When click Burn, get the same prompt about not
enough space unless finalize - and the burn was successful again without
finalize - that is, about 14M came from nowhere.


Read about the 1st session overhead:

Subject: How much data can they hold? 650MB? 680MB?
http://www.cdrfaq.org/faq07.html#S7-6


Good article.


Think about this: The nominal stated disc capcity is after the session
overhead of 23M is accounted for. That is, if you burn DAO, you can
burn 650M actual data. But if you burn multisession, the 23M of DAO
overhead sort of disappears.



As for the message, "There is not enough space available to burn this
compilation unless the cd is finalized after burning. Do you want Nero to
finalize it after burning?", that confuses me. I don't know why it seems to be
saying that if you finalize there will be enough space and if you do not
finalize there will not be. Doesn't finalizing use up some additional space?

Finalize does not use up additional space - and neither leaving it open
does, based on what I read. (The last lead-in is supposed to have a
