Yes I'm a bit late on this reply - but to add to Bernie's replies:

Nero InCD does the full format of CD-RW media as a background task -
either as you write to the 'blank' or 'erased' platter in CD-RW (Packet)
mode,
or while other things are happening

That's why there is sometimes a noticeable, or even reported delay when you
try to eject a CD-RW platter -
It's the system either completing the formatting, or marking the platter
with information as to how far it got with the full formatting

You may notice that writing CD-R  or DVD-R format to CD-RW or DVD-RW
using Nero reports verify fail on sectors 30 on
That's because the INCD process was formatting a RW platter it noticed being
inserted after the main Nero process had written to it as -R media

Once InCD has recognised that the main Nero process is writing to the
platter ( found data and is erasing the disk) InCD won't do the format
again.


Re. verify -
I use Karenware DirPrt with MD5 hashing and Par's for recovery sets on
important data,
gives me a list on HD of what is on which platter as well as checking the
platter matches the data I wanted on it, and reports errors using filenames
with the added benefit that the PAR set usually allows re-creation of the
occasional damaged file.

and check/ create new copies after the platters are 1 year old

They do deteriorate, and there are some DVD platters that are not sealed at
the edges, and/or hub, so they let in damp, and fungus to destroy the dye,
they may even separate
