Not Able To Write Disc-at-once On An Open Disc

[auto7890]

what does this mean as my english is not so good.
Does this mean I can throw my 4.3 gig disc in the bin ?

Nero says its got 4gig free available on it. But when I try to burn data
on it it just comes up with a message, "NOT ABLE TO WRITE DISC-AT-ONCE ON AN OPEN DISC".
I think it may have some small data on it. Is there a program that can fix this ? what happend was I used another burner to burn,but immediatly stopped the burning after I changed my mind.

You may be able to format it for drag-and-drop, but you will not be able to use it for disk-at-once burning.

============================
Because I am a newbie , would it be possible for you to show me
where in Nero we format disks ? like as in a upload picture ?

Also is it safe to format a write once only DVD ?
and can it be formatted if its got some data on it already ?

The term "disk-at-once" I am still not clear with. Does this just simply mean you can not burn straight away ? and if so how long do I have to wait until I can burn it at once ?

Or is it a matter of changing over to burn as a CD instead of a DVD wich means I can not put on anymore than 700meg on my
4.3meg DVD disk.

A little self-education goes a long way - I'm sure there is documentation with Nero that explains all your questions. Unless you're in a country that charges a large tax on blank DVD media, just throw it away and start again. Regarding your other post, Nero isn't "going backwards," you just screwed up. Don't blame Nero.

I don't use Nero anymore, so I can't make a picture.

"Disk-at-once" is what the term implies, it's a one-time burn where you select all the data you want, then it's burned, finalized and closed, and you never write to it again. It's generally the most reliable and the most compatible method.

Session burns are for adding more data later, and while some PCs can read the disk, most everything else can't until it's finalized and closed, and even then some of standalone devices can't read it. There's also wasted space on the disk because each session has to write a new header.

If you format a previously written "one-time write" disk that has data on it, that data is lost. It doesn't actually format the disk, it just creates a new lead-in track outside the previously burned area, and the rest is wasted space.

Disc at Once (DAO) is also the recommended way to burn audio CDs (especially concept albums or live recordings), as it's the only way to avoid the 2 seconds blanks between tracks. In Tracks at Once (TAO), the gaps between tracks are necessary.
