unreadable dvd

[ballondo]

Greeting to everyone.

Recently, I use Windows XP to copy file or to transfer
file from my computer to a DVD burner.

As soon as I finished, I verified that all the files were
written on the DVD as they suppose to.

A few week later, I was trying to access the files on
that dics, it seem that 90% of them cannot be transfer
from the disc to my computer, they are sort of unreadable
even though the files do exist on the DVD disc.

when trying to copy the files from that dics, I obtain
the following message: data error (cyclic redundancy
check)

I was wondering if any savvy can help me out, I have
hundred of dollard software on that dics.

Thank you all

XP has no native DVD burning capability. In order to burn DVDs, you need
a third-party application.

This problem has nothing to do with DVD Burning capabilities. Read the
entire post before you reply. The OP already burned the DVD and now
can't get data off the DVD.

This can happen frequently in the following two scenarios:
1) The DVD Burner did not burn well. This could be due to too high of a
speed, buffer underrun errors, or just bad laser calibration.
2) The DVD Media is cheap. This can make the data go bad quickly or not
burn well.

It could be a combination of both or something completely different. I
would suggest trying to read the DVD in another computer and see if that
computer has any luck. If it has no problems, it is your DVD Drive with
the problems. I have a feeling the DVD you burned has gone bad (usually
shows CRC errors as you mentioned).

Sorry for the confusion, but perhaps *you* didn't read the first
sentence of the post, and went ahead and anwered without having any
indication of what the OP's problem might be.

The OP never said they used Windows' native burning to write the DVD.
They said they used Windows XP. This could be as opposed to Linux or
some other OS. Since XP Doesn't have the capabilities to burn a DVD,
how in the world did the data get written to the DVD? Also, the OP said
they verified that the data was written to the DVD. This could mean
they browsed onto it, or it could mean that they used a program such as
Nero to burn the DVD and then have the program verify that the data was
written to the DVD. The option to verify is right there on the burning
page.

True the OP was unclear, but just telling the OP that they can't burn a
DVD without DVD authoring software doesn't answer any of their
questions. I just want to know how the index of all the files and
information about them got written to the DVD since XP won't burn to a DVD.
