MP3 Files From A DVD-RW Disc

[John]

Hi,

I was cleaning up my harddrive and I decided to copy my
MP3 files to a DVD-RW disc that had been rewritten 5x
previously.

Question 1: Approximately how many times can a DVD-RW disc
be rewritten?


Question 2: Assuming that the MP3 files are then copied
back to my harddrive and it shows up in Windows Explorer
WITH appropriate icons (Winamp)AND looks to be the right
file sizes (I didn't make note of this beforehand )is
there any chance that the MP3 files are somehow degraded
by missing bits of data? ****And if this was the case,
would the Mp3 files play back in Winamp, or would they
play but with errors like clipping, noise, etc?**** How
would I know? Is there any test I can do with some kind of
software?

(I don't know much about MP3 files but I would prefer that
any corrupted MP3 files not play back so that I would
actually KNOW that they are corrupted from their original
state. ...this is what my question is all about in other
words)

TIA,
John

Depending on manufacturer, generally a few thousand times.

If there's a misread or bad spots on a disc, error correction won't let it
be read incorrectly. If a spot goes bad on the disc, you will know it,
it'll show you a read error and stop.

.
Let me try to understand this:...generally when copying

files to a disc, bad spots will ruin the disc and the
burning process will immediately stop. But when reading
files from a bad-spotted disc, the file will generally be
read as is to completion. So a file from a bad-spotted
disc may or may not be corrupt depending on the severity
of bad spots? An example of this would be ripping a music
cd to your harddrive. There would be no problem reading
the files on the disc to the harddrive but because of
possible bad spots the music files may contain noise,
blanks, etc...
