Problem with back-ups

[glitch19732000]

My kids recently scratched the heck out of my original copy of Cars. I tried to make a copy of my back-up disc so the had one of their own and I keep getting I/O error. The back -up disc is not scratched and it plays but I cant seem to copy it. I tried decrypter and dvdfab and dvdfabhd. I am new and confused. So I tried some of my other copies. Some worked and others didn't. Is it my burner? Please help.

There are different protection schemes used on different DVDs and you have to have a range of tools available to defeat them. For Cars:

Note: I found this by putting this into Google:

This trick for using Google to search Doom9 is very useful. :)

If you have previously successfully copied it and now your backup gives you this error, then you may have used poor media, but also try a different computer. setarip_old will also probably be along shortly to help from his vast experience with DVD and backups.

I was also wondering. Might I need a new burner. Mne is a sony and itis 2 years old. Seems to be taking longer now to burn copies too almost twice as long.

by poor media do you mean bad discs?

[laserfan]

What burning software did you use for this disc, and did you have the "Verify" option (assuming it has one) and use it to make certain that your backup was good?

You could have made a bad backup originally (if you didn't verify) or as neuron2 has suggested used poor quality media which didn't "hold" the burn over time.

Something to try for grins might be to run Nero CDSpeed utility on the backup to see if it reports having trouble reading the disk.

Hi!Seems to be taking longer now to burn copies too almost twice as long.Your burner may be failing or, more likely, it has reverted to "PIO" mode (as a consequence of cumulative errors).

To once again get the burner into "DMA" (much faster, less eror prone) mode, do the following:

In the Device Manager (via the Control Panel>>System>>Hardware>>Device Manager), you simply have to remove the applicable IDE channel (Click on "IDE...Controllers") and let your computer reset it to DMA as follows:
Right click on the pertinent channel in Device Manager
Click on uninstall
Reboot
After rebooting go back to Device Manager and change the setting to "DMA if available"...

burner is in DMA mode..... I think it was a bad set of discs. Discs from other sets are working. I used cheap memorex discs. I usually use maxell. Also is it better to use -r or +r
I always use -r

I prefer +R discs book-typed to DVD-ROM.

Try making an image of the backup using ImgBurn. I'd mount and see if it plays w/o problems and then I'd burn a new backup using the image.

I've used many different brands of media both -R and +R and I've found that Verbatim +R discs are the way to go. Other good discs would be Sony, Fujifilm, or even TDK, but [B]I[B]wouldn't venture away from those. I found that most other types of media discs either wouldn't even play in most DVD players or had a high rate of defectiveness.
I would suggest to try and stick to a better quality disc (even though it may be a few cents more expensive per disc) and then troubleshoot from there when you have problems. Otherwise, you find yourself digging way too deep into what the problem might be when most of the time it's probably just something as simple as the quality of disc or burner that you're using.
