No you cannot, but not because the cd is not finalized. It's because you simply cannot erase data unless you are using a cdrw. You can
, however, make the existing data hidden so that your operating system will not recognize it. Just treat the data cd as a "New Multisession" if you are dealing with Nero and it will write the new data without making the older data accessible.
In this case, whether done on purpose or mistakenly, you can use specialized apps like Isobuster
to read all sessions written to a cd, extract the info you want, then reburn it to another cd.
how long (in seconds) approx. will it take to finalize the cdr?
Not long at all: 10 - 20 secs maybe. Do not let this be a factor in determining whether or not you will finalize a cd. Rather, use it when you are making an Audio CD in DAO, OR
use it when you have written data to a cd and you do not intend to write any more data to the cd. This will ensure that the data is safeguarded should you mistakenly use it for another data burning session where you can make a "New Multisession" that will render the old data unrecognized. Fortunately, if this should happen, you can use Isobuter to read the cd and extract the older info that you want to keep.
And does finalizing it have anything to do with writing the Lead-Out of the cd?
I don't think so. A lead-out must be made in a mult-session cd in order to link the new data to the old so that all data will be recognized by your operating system. If I'm wrong on this somebody will correct me, but as far as I know, it has nothing to finalizing (unless you are actually finalizing maybe?)
