Learner, More Information Please
by Grif Thomas Forum moderator / July 3, 2006 4:06 AM PDT

Are you trying to copy data from a CD/DVD to your hard drive or from something else..

The error you've listed is easily found by searching Google. In your case, it appears like the data on a CD/DVD has been corrupted. Data on formatted disks will occasionally throw that error.

For examples, see the link below:

Hope this helps.

It means failure.

Either the place from where you are copying it is going to be completely destroyed, or your hard drive is about to fail.

If its a floppy, then you have a dead floppy disk. If its a cd, the cd is scratched badly.

with a dvd recorder?

I believe it was

The DVD came from a friend who uses (I think) some kind of DVD recorder to copy video Christian messages to send out. They are not copyrighted, I don't think he uses a computer to do it. He is not computer literate, (but I'm not much better!) But I have found the same problem. I bought a DVD recorded+Video, and they won't play on the computer, only on the machine they were recorded on. And I was trying to copy his DVD on my computer. Some of the files are OK and play and copy, but just this one failed.

That's what I thought.

It's been my experience that a muti-session recorded dvd will do that but it should still PLAY with most dvd player though (not just the recorder). I usually just re-record into a single session dvd. However, there maybe software out there that can take care of this problem (that I am not familiar with).

After I make a single session then I can make backup copy using "dvdshrink". A little bit involved but it can be done.

If you are going to try it, do it with RW dvd first. Good luck.

DVD Shrink

I do have that program on my computer, but haven't the faintest idea to use it, its probably beyond me, I don't even know how or why I have it!!
Also I don't understand 'single session' against multi session, or how I can select one or the other. I have two programs, Nero and Recordnow Max. If one won't work I use the other one.

What I was talking about only applied only to...

stand-alone recorder; or maybe just the one I have (AdjureDigital).First of all the format it use is not the same as the commercial dvd that you get from the store.

As for session type, I was just referring to dvd that was recorded with stand-alone dvd recorder only (not burned from a computer).

question; Are you able to play this dvd at all, either on the computer or stand-alone dvd player? If it play then you can tell whether it's single or multisession. If it doesn't play, then you might have a corrupted dvd.

Stand alone recorder
by Learner7 / July 4, 2006 7:37 PM PDT

Yes, the DVD sent to me was copied on a stand alone recorder, that was the DVD with Cyclic problem. And he is sending me another one.
The one I copied on a Toshiba stand alone recorder won't play on the computer, but when I put it back in the Toshiba it plays OK, so I think there is something I must have missed. I wanted to make a few copies to send to friends, but know some of them only use their computers, that's why I tried it to see if it would play on mine!
Thank you for explaining the sessions to me.
