Mike Richter (Slimy ****) crapped:

A disc needs to be formatted before it will permit drag-and-drop.

A "virgin" DVD+RW needs to be formatted prior to its use even for
mastering.

There are two formattings: (udf) formatting and (plain) formatting.
DVD+RW needs to be (plain) formatted prior to its use. (udf) formatting
is built on top of (plain) formatting.

When Nero burns a mastering session on a 'virgin' DVD+RW:

"Start formatting disc before burning"
"Formatting disc was successful"
"Start write address at LBA 0"


Erasing is erasing and in itself does not format;
in fact, it destroys formatting if present.

DVD+RW does not support erasing. DVD+RW formatting does not get
destroyed.

DVD+RW specification does not support erasing. However, this does not
prevent software/burner to implement some sort of "erase" functionality.

In any event, the (plain) formatting does not get erased.

The rationale behind DVD+RW not supporting erasing is that it is not
necessary (as overwriting does it). It only unnecessarily takes away one
cycle from the overwritability.

.
Mikey, is there an end to your spreading misinformation?!

.
Any program which offers to format a disc should be fed one with nothing
recorded. Given the way it is done, formatting s/w will either refuse to
work on a disc with data or will make those data unreadable -
effectively if not actually erasing the disc.

Is this Mikey's wise words of the year?

The dialog has both Erase and Format functions. What is the difference?
SCSI MMC has ERASE.

One of my DVD+RW has a faint arc scratch, which shows up as hard errors
at 3GB.
Should erase pick this up? The laser has to switch between read
(tracking) and writing, and can detect some flaws during the former.



I have read that Liteon produces a DVD drive that has Smart Erase - a
function that permanently and completely erases ALL data so that no one
would ever be able to extract data from the disk. It could be that Nero
takes advantage of capabilities like this when it can.

Better not believe that. The information on how well you can erase
optical media is sketchy. Sure, another plain optical drive will not
read erased data. But it may or may not be possible to read it with
special hardware.

You do not actually need special hardware to recover quick erased
disks. I have worked on a technique where DVD-RW (and CD-RW) can be
recovered using standard hardware. On a DVD+RW the data is normally
easily readable with a standard drive even when the DVD is apparently
empty.

The only secure erase will take time - probably at least 5 mins for a
DVD and probably longer. Anything less, don't trust it.

Is that an open nerv I hear sounding through, Roddy?
It wasn't really your best week, was it.
