DVD Bruner Question

[Bob]

I burned 2 DVD's with software on my harddrive to make room for other
stuff. The odd thing is that one of the DVD's is accessible, whereas
the other isn't. If I take the inaccessible DVD to another system with
a DVD reader - it works. Any ideas?

Crappy media can do this, and it will get worse over time. I'd make a backup
of that data before it fails completely.

What is the manufacturer ID of the media? Most burner software will show it
in the "Disc Info" someplace.

Sometimes when doing a burn, there may be some data that is not defined
properly in the disk. This will happen more often when doing the CD burn
at very fast rates. Using the slowest burn rate will produce the most
accurate disks.

When burning the disk very fast, the data pits or burn transitions are
not as well defined, thus making it more critical to read the disk.
Using slower burn speeds will result in more reliable compatibility for
reading the disk.

There are tolerances in the alignment accuracy in the alignment of the
disk drive laser units. This factor will add to how critical the reading
will be between drives.

Actually, this isn't true... I'd post the link if I had it handy.

There were a number of folks who did identical burns at their fastest rate
on DVD and CD media, then again at the slowest rate of the drive. There were
far more errors on the slow drives. I found this in a support forum online
when I was researching media quality after getting a bad batch of DVD-R...
(P.S. avoid FORTIS discs)

I would have guessed that the slower disks had better pits, but it's not the
case.

How slow was slow in that test? Some people were arguing that it was
ridiculous to burn disks like some posters claimed they do from time
to time at a mindbogglingly slow speed , thinking they are getting
better burns. Supposedly newer formulations are geared for a certain
range of faster speeds. However , they still seem to struggle with
various media and burner combos in the highest speeds ranges which
makes sense. Anytime a new higher speed comes along it seems to take a
while for them to perfect the media and burner firmware .

My CD drive by now an aging 52x and my NEC 2510a 8x --- both seemed to
have problems with faster media. I limit my burns on Liteon 52x to 32x
now after I had lots of problems once with some cheapo media over that
speed. SVCDs started getting horrendous problems right near the end
before then I was getting consistently good burns but the media was
still limted to 48x. Since then Ive had several incidents where
anything over 32x produces artifacts on svcds.

The DVD burner too , Ive had to slow it down to 2x instead of 4x.

However where Im at we dont get access to the super cheap deals on
stacks of 100 dvds that supposedly can burn at 8x like Riteks etc
Shipping adds like $20 or more to the deals so they kill the deal. So
that might make a huge difference.
