CD writing "multisession disc"... does it have to be a CDRW to add a file later?

I used Nero 6 to burn a compilation and discovered that one of the files included was the wrong file. I did "multisession disc", so I figure this means I can add the correct file if there's enough disk space. Is multisession only for CDRW or DVDRW disks? Or can I do it with my CDR? Nero is telling me the disc inserted isn't writable, so this makes me suspect that this will only work with rewritable discs. Is that the case?

Multisession works on CDR. Stuff can't really be deleted so "deleted" stuff still takes up disc space, but is no longer accessible.

It doesn't have to be a RW disk if you burned it originally as a "Multisession Disk ".

Here are instructions:

http://bib.kuleuven.be/ebib/data/handleidingen/cdrom.pdf

Creating a Multisession CD
We will show you, step by step, how you use Nero to create and record a Multisession CD. Nero
allows you to record a Multisession CD from a blank disc.
If you want to continue writing a Multisession CD, please see 'Continuing a Multisession CD'
We will leave all the options with their default settings.
Follow the instructions carefully. Good luck!
1. Click on the CD-ROM icon in the New Compilation dialog window which opens after you
start Nero. If you have already opened Nero, you can reach this dialog window through the icon
for "New Compilation".
On the property sheets, the Multisession card is on the top.
2. Please select the Start Multisession disc option. Make only sure that the No Multisession
box is not activated.
3. By opening the property page File Options you can switch between Mode 1 and
Mode2/XA. The mode settings can be found in the upper right corner of this page. If these
settings appear dimmed/disabled, then these settings can't be modified right now. This might
for example be the case if you created the ISO compilation using the option 'continue
multisession'. If you would continue a multisession CD using a different ISO- or sector format,
then you would be in danger of creating an unreadable CD.
4. Now click on the New button at the right.
The corresponding blank compilation window for CD-ROM opens.
5. Using drag&drop, compile the files for the CD by clicking on the desired files in the File
Browser with the mouse and then dragging them into the compilation window.
6. If the File Browser has not yet been opened, you can do that now by entering the
VIEW>New File Browser command or by clicking on the File Browser icon.
7. Now open the Write CD dialog. The easiest way to do this is to click on the Write CD
icon in the toolbar. You will then go to the Write CD dialog box, which will undoubtedly look
familiar to you: It is the same box which you saw for the creation of a new compilation, only
now the Burn property sheet is shown on the top.
Important: make sure that the Finalize CD box is not checked, unless you don't want to write
your CD again, after this session!
8. Now you may confirm by clicking on the Write button. All of the selected steps will now
be carried out in sequence including the burn process. So that you can follow exactly what is
happening, a status window is displayed in which the individual steps are listed.
9. As a last step, you will see a message like "burn process was successful with 12x(1800
KB/s)".
10. Finally, the CD will be ejected.
You may now check to see for yourself what was written onto your new CD by re-inserting the
CD and clicking on the CD info icon.
Continuing a Multisession CD
We will show you, step by step, how you use Nero to continue writing a Multisession CD.
We will leave all the options with their default settings.
1. Insert the Multisession CD, you want to continue to record, in your CD writer.
2. Click on the CD-ROM icon in the New Compilation dialog window which opens after you
start Nero. If you have already opened Nero, you can reach this dialog window through the icon
for "New Compilation".
On the property sheets, the Multisession card is on the top. Make only sure that the No
Multisession box is not activated, otherwise you are not going to write a multisession CD, but
an ISO CD!
3. Please select the Continue Multisession disc option.
4. By opening the property page File Options you can switch between Mode 1 and
Mode2/XA. The mode settings can be found in the upper right corner of this page. If these
settings appear dimmed/disabled, then these settings can't be modified right now. This might
for example be the case if you created the ISO compilation using the option continue
multisession. If you would continue a multisession CD using a different ISO- or sector format,
then you would be in danger of creating an unreadable CD.
5. Now click on the New button at the right. The Select track dialog box opens.
6. Select the track that should be backed up. It will be generally the last ISO track. For
this reason, Nero selects it by default.
7. Click on the OK button. The corresponding compilation window for Multissession CD
opens.
This window displays all information concerning the track you have selected. Depending on the
refresh options selected in the multisession property sheet, you will see some folders and files
shown in black or in grey.
Folders and files shown in black designate that they have been changed or recorded on your
hard disk since your last session. They will be recorded on your CD now.
Folders and files shown in grey designate that they are already on your CD. They have been
recorded during your last session and have not been changed. They are not going to be
physically rewritten.
8. Now open the Write CD dialog. The easiest way to do this is to click on the Write CD
icon in the toolbar. You will then go to the Write CD dialog box, which will undoubtedly look
familiar to you: It is the same box which you saw for the creation of a new compilation, only
now the Burn property sheet is shown on the top.
Important: make sure that the Finalize CD box is not checked, unless you don't want to write
your CD again, after this session!
9. Now you may confirm by clicking on the Write button. All of the selected steps will now
be carried out in sequence including the burn process. So that you can follow exactly what is
happening, a status window is displayed in which the individual steps are listed.
10. As a last step, you will see a message like "burn process was successful with 12x(1800
KB/s)".
11. Finally, the CD will be ejected.
12. You may now check to see for yourself what was written onto your new CD by reinserting
the CD and clicking on the CD info icon.

too long
spend the 5 cents and just burn a new disc.
Whoa, where do you buy CDRs for a nickle? Best price I could find was two 100 disk stacks of Sony's at Office Depot. Buy one get one free was the deal. Net after taxes was $0.17 per disc.

Maybe I can't add to the compilation because I didn't save the session. Does it work like that?

frys....generally 100 spindles go for like 10 bucks from time to time, im sure you can find similar online. i was off by a bit, 10 cents is still nothing. its hard for them to sell for more when 100pack dvdr is 15-19 all the time.

I've seen them at BigLots for $12 per 100. I don't like using CDs if I can help it. A spindle lasts me damned near forever. The point still remains though. Even at 20¢ per disc, my time's more valuable than that. To put it in perspective, my Net10 cell is 10¢ per minute. If dicking with a CD takes more than 2 minutes, I'm losing money.

why not use dvds though, the price per mb is so much better, a cd would have to be like 6 times cheaper just to match a dvd.
plus dvds seem more robust, cdr flake and scratch so easy.

The main reason I use CDs is for disposable storage to give people programs and data(usually smaller than 700mb), and to make mp3 discs to play in my car so I don't have to use my mp3 player. I don't really use optical media otherwise.

I finally gave up and burned another CDR. This time I saved the compilation, didn't close Nero and found that I could add another file, and did. I'm going to see if I can open Nero, the compilation again and add another file or two. If so, I'm going to save my compilations in the future. I didn't used to as a rule because I didn't know why I'd want to.

I use DVDs when the storage requirement is above ~700MB, otherwise, a CDR, as in this case.

Myself, I don't usually write MP3s to CDRs, because I no longer use my portable MP3 players, which use CDRs. My CD players aren't MP3 capable, with the exception of my computers, however for my computers I just write to HD. In this case it is MP3s I'm writing but it's to distribute them to others.

It's very simple - a disk can stay "open" until you close it. This is part of packet writing.

I've never had a multisession CD go wrong, ever FWIW. :\ Only problem is, each time you "multisession" the disc, you lose some space (I want to say around 30 mb, but I can't remember off the top of my head). When you add a lot of little files, this "buffer space" takes a lot.

NOOO. You don't have to save the compilation just to add another session to the CDR. You didn't read what I posted did you?

After you burn the Original Multisession CDR do the following to add files ( create another session on the disk ):

1. Insert the Multisession CD, you want to continue to record, in your CD writer.
2. Click on the CD-ROM icon in the New Compilation dialog window which opens after you
start Nero. If you have already opened Nero, you can reach this dialog window through the icon
for "New Compilation".
On the property sheets, the Multisession card is on the top. Make only sure that the No
Multisession box is not activated, otherwise you are not going to write a multisession CD, but
an ISO CD!
3. Please select the Continue Multisession disc option. ..... see my huge post above.

When I do this I see two buttons I can press:

[New]

[Open]

If I press New, I immediately get a message that the disk is not writable and I see nothing I can do. If I press Open, I'm prompted evidently to find a saved session, and like I say, I didn't save the session. Maybe I'm missing something. What? :\

I'm confident that the disc was created multisession, that's the default and I never change that, because it has always worked for me. However, when prompted to save the session, I usually don't, because I figure I'll be done with it. In this instance, I want to write another file...

Short Answer. No!
Uh, to what? I've been told before that "the world says no." But in this case, I'm wondering just what you meant? How about the long answer?

I made two discs, and one I was utterly unable to add another file even though it wasn't terminated. The other I did add a file. the first is in my trash.
