110251	2003-01-01 02:35:00	Hi everyone, Im a newbie when it comes to using CD Writers. I have nero 5.5v10, and the program is fairly good to follow. Though, I am confused when it comes to "multisessions" on a CDR. What I don't really understand is, how do you delete the previous sessions? Is this possible? I found out, that I should of continued from my previous session rather having to recreate another one. What I also don't understand, is that after doing a burn, I find that the total capacity of a CDR has changed from my last multisession, thus the capacity of the CD still mounts up without even knowing the precise amount left over. I hope this is all sense. Has anyone got any best suggestions to share? Thanks	sandy beach (1540)

Yes, Continuing the session is a good idea, you can simply delete the files you dont want to show up on the next session, but there is software that will let you see previous session on CD-R's! > What I also don't understand, is that after doing a > burn, I find that the total capacity of a CDR has > changed from my last multisession, thus the capacity > of the CD still mounts up without even knowing the > precise amount left over . Umm . . . Well, I think to answer this, each time you burn to the multisession CD, It has to add an extra 14MB of data to "close" the session and basically write on the CD that it is closed . Note, this is different from being finalized, as a finalized CD cannot be written to, but you need to close the CD for it to be readable in CD-ROM drives! Hope this makes sense Cheers Chilling_Silence	Chilling_Silence (9)
110253	2003-01-01 02:58:00	On a CD-R, you can't delete previous sessions, whereas on a CD-RW you can, because it is re-writeable. While it is fine to write a CD-R in more than one session, this wastes space and is not normally done. If you're only writing one type of data source onto the CD (eg just audio), you'd only want one session, unless you wanted to close that session without finalising the CD, and add some data such as files on the rest of the CD, then finalise the CD. This is how bonus CDs with videos as well as the normal audio tracks are made. If your CD writer supports it, I would recommend writing in Disc-At-Once or Track-At-Once mode. TAO mode writes each track, in one session, with a gap of about 2 seconds between each song, while DAO mode has no gaps, but still writes all the songs in one session. I'm not completely sure about what you mean by saying "the capacity of the CD still mounts up without even knowing the precise amount left over", but I'll have a go explaining. Most CD writing programs, after having written onto a CD but not finalised it, will estimate the remaining space/time left available on the CD. It cannot get the exact amounts because of different file systems, having to make new sessions or closing old sessions, and finalising the CD. These all take up space, which is why the remaining capacity is estimated.	agent (30)

While technically you can't "delete" the data, it is removed by altering the table of contents. > While it is fine to write a CD-R in more than one > session, this wastes space and is not normally done. > If you're only writing one type of data source onto > the CD (eg just audio), you'd only want one session, > unless you wanted to close that session without > finalising the CD, and add some data such as files on > the rest of the CD, then finalise the CD.

Nero allows Disc At Once and allows specification of gaps between tracks to. Also, cd-writers support both DAO and TAO writing methods. You'd really need a stone-age writer (sub 8x) to only get TAO. > I'm not completely sure about what you mean by saying > "the capacity of the CD still mounts up without even > knowing the precise amount left over", but I'll have > a go explaining.

110255	2003-01-01 09:00:00	I have to agree with Lo. on this. However, with Audio CD's, you can simply not "close" the session, and re-burn to it later. However, until the session is closed, or the CD finalized, it will not play on most stereo systems. Another thing, with a CD-RW, it is recoverable (to a certain extent) if a "Quick Format" is done. If a "Full Format" is done, then the data is not recoverable because it has been fully written over. Similarly, if a quick format is done and the CD re-burnt to! As for the TOC, Yup, I thought so too! I had NTI CD-Maker which said (in its hundred odd page manual) that when you wrote a new session on a multi-session CD, It had to burn an extra 14 megs of data, which closed the session by re-writing the TOC. Please note that Nero also adds a few extra megs of data, usually about 2 megs, to each session which is not readable, it is used by Nero in multisession CD's to note down the location of entire folders that were copied across. So say you simply drag across your My Documents folder, and burn it, It makes a note in its wee "special nero file" or whatever, that you burnt the folder My Documents, located in the C:\ directory (or C:\Documents and settings\username\ if you're on XP/2K) and it contained files X, Y, and Z. Now, say in your My Documents folder, you write a letter to your dear aunty, and also edit a file you have been using to keep track of your bank budget. Insert the CD into the drive and load up Nero, and it does a quick check and notes that a new file has been created in the My Documents folder, and an old file updated, so it automatically gets them ready for you, IF this is the option ticked when you select "continue multisession CD" (in non-wizard mode.. I've never used the wizards). You could then hit Burn without any further intervention and it would update for you :D Easy as that... Just thought Id share that little snippet of information. Quick question : Does Roxio CD-Writer do this? Hope this is all clear enough Cheers Chilling_Silence	Chilling_Silence (9)
110256	2003-01-01 10:37:00	If you ask me, it's simple file synchronisation. I have the OEM version of Roxio whatever-it's-called-since-they-took-over-from-Adaptec, which is not the Deluxe version obviuosly, and it doesn't have a feature like that (not that I would use it). I did find however that they include a nice tool to recover lost files of CDs, which came in handy for me one day. I also discovered a while ago that Nero doesn't completely finalise CDs so that you can't add more data on afterwards. So say you write a 300MB file onto a 650MB CD, and finalise the CD so it can be read on a normal CD drive, you can put it back in to your CD burner and write more data. I know this sounds good, but I like Roxio's popup box where you select how you want it finalised, such as not at all, so it can be read in normal CD drives, and then a little checkbox that says "protect from future writing".	agent (30)
110257	2003-01-01 11:10:00	Hi again everyone!! Thanks for your help. All of your information has been really helpful to me and is much appreciated. Thank You Sandy Beach Just a thought............ When copying data, onto CD's, could there be a reliable brand out there? Or is this a matter of trial and error? I'm guessing that Maxell CDS are good or TDK?	sandy beach (1540)

Nope. You finalise a CD-R on Nero, and you can't write to it any more. Full stop. Nothing more to say. Lo.	Lohsing (219)

I'm guessing that Maxell >CDS are good or TDK? It is trial and error. Generally the "name brands" are more reliable but a lot of people find that the cheap Harvey Norman or Warehouse brand disks to be fine. It depends on what your writer decides it likes. Buy one or two disks and try them out before buying them in bulk.	tommy (2826)
