Vista - Read me first yellow sheet in new computer box

Hi,
One by one you all have helped me resolve my problems. Thanks. Here's one
that is puzzling me. When we first opened the box with the new computer
tower in it, I noticed this yellow sheet with bold print on it saying "READ
ME FIRST When creating audio, data, or backup discs, verify the disc after
recording to optical media to confirm the data was written successfully."
My question is this ... how do I verify that the data was written
successfully?
Nancy

With individual files, you could access the saved files - confirming
that they are intact.

With back up or imaging utilities there may be a "verification" step
that can be employed during the back up process...or after the fact.
Check the documentation, or talk with a tech person who is versed in the
operation of the back up tool that you are using, so you are certain
that you understand how to use it.

Really long answer... <wink>

It depends on the data. If you are just backing up files, like a
spreadsheet or your secret recipe for Angel Food cake a simple verify
is all you need and there is lots of software that can do it
automatically. Nero probably has a option for many tasks, since I'm
using Easy Creator I KNOW it does. It does tend to slow down the
process. If you always want to write and verify, the data you burned
gets read back and compared byte by bytes to see if you got an exact
duplicate, depends on the importance of the data.

Now the bad news. Burning both audio and video files is different.
Unlike the commerical process where copies are made from a "master
copy" and actually the data is embedded on the disc under pressure,
similar to how dollar bills are printed from a master engraved master
under high pressure when you do home brew DVD creation the process is
very different and many errors can creep in. Therefore if this kind of
data is important to you the only way to verify is play it back and
watch every minute of it if its a video.

Here's why:

1. Bad media. The blank discs you buy may have flaws. You rarely can
see them, but the laser trying to read them sure can and just a
very slight imperfection may cause the laser to bounce the light
ever so slightly off track and you'll get a glitch meaning the DVD
will stutter, stall, show artifacts, breakup, distort the audio or
simply refuse to play at all or just stop at some point.

Sorry, no cure. Just a fact of life. For every 100 disc stack of
blank media you buy expect one or two to be bad. Sometimes way
more.

2. It could be your DVD burner. As a DVD gets encoded tiny errors
should be compensated for, this is build into the firmware. Again,
sometimes this exceeds tolerances and while your DVD burner may
say it encountered a error during the burning process and just
stop and then spit out the DVD that now is just a coaster, errors
non the less can happen and there's no way of knowing unless you
play the disc all the way through.

3. It could be your DVD player. Especially true for set top boxes
you attach to your TV to play DVDs through your televison. Again
the tolerance can be such Brand A may not be able to handle media
that Brand B can, or be less sensentive to flaws. A bigger issues
is people use the wrong bitrate to encode their DVD to. Most people
think more is better and will use the highest bitrate the
application supports. While there are standards, the sad fact is
many DVD players can't handle bitrates in the high end of the
tolerance range and can show all the symptoms of a bad burn I
mentioned earlier.

4. Could be the brand. Not all blank media is created equal. Some
simply refuse to be read in some DVD players, yet they will
play fine in another, often play fine in your computer. This is
typically due to differences in the reflectivity of the coating.

Which brings me to my last warning. If you burn DVD's and plan to
view them on a big screen TV in the den, don't test them on
your computer and assume if they play fine there they will
play fine on your big screen. Test on the device you plan to
watch the finished DVD on, otherwise you may be sorry and no
longer have the source files to try again.

So to be sure, if what your burning is important to you and we're
talking audio or video, the only way to be sure is play it all the way
through and verify that way it is a good copy.

Low tech way to verify media: do a search "in files" for text unlikely to be
found, e.g., hmm... "elephant" or "ElephantsOnParade". Search will open each
file to search within it for text. If search can't open a file, it's
corrupted, and search will gen an error.

Well, that leaves me feeling kind of flat. <LOL> I can see what you mean
though. Thanks you for the explanations. I would hope the flaws are far
and few between but wish there were an easier way to tell.

I'm trying to remember exactly what happened when I burned my recovery
discs. I do think it went through some kind of checks but not sure. Since
you can't burn them a second time I can't do it over to make sure I got it
all right. I have to just hope for the best.

Thanks for all the time you took to explain all this to me,
Nancy

OK, then ... if I put my recovery disc into the E drive won't it
automatically come up trying to format my hard drive? (I never used
recovery discs before as you can see) This is a good idea and I plan to use
it for my other discs but not sure if I should put the recovery disc in.
Thanks,
Nancy

Well... I guess I can't answer with complete authority because I don't know
what type of recovery disk you're talking about. I would be very surprised
that any recovery CD would try to automatically format a drive. Wouldn't
that subvert the whole idea of "recovery?" One can't recover what's been
formatted.

Rereading your original post leads me to believe that you mght be overly
concerned about a statement that I would categorize as a "disclaimer" type
statement. "Don't blame us if you've created an audio CD and it won't
play... etc., etc., etc."

It's easy to verify audio disks; try to play them. Data disks? Try to open a
file you copied to it. Backups? Try to restore.
