*ack* Need some help here (DVD Burning)

Hmpf!

I had about 4GB of processed scientific data that I wanted to get off the individual Systems and burn on a DVD.

As an intermediate Solution, I collected everything on a DVD-RAM.

Yesterday, that DVD-RAM was full and I decided to burn it onto a Regular DVD+RW for permanent storage.

Now, Nero6 copied the Files directly from the DVD-RAM and burned all of them onto the DVD+RW (File compare was 100% okay after the process).

But :
Today, I needed to look something up on the DVD+RW, just to find out 3 different DVD Drives can't read anything from it.
There definitely is Data on the Disc, but I can't access it, therefor I must assume the Files were not burned in the standard Data Mode, but (possibly) in DVD Video Mode Tongue

Is there any way to check what went wrong and (if possible) copy the Disc back into a usable Format again ?

If not, I lost about 8000 hours worth of Science, which would suck big time Undecided

I ran into something like this once, I had a disc that was multisession and the all the computers could only see the last session!

Use Nero and view the disc in file explorer. In the file explorer window right click on the disc -> properties -> volumes.

If you are lucky as I was there will be an alternate volume listed and you can choose it and it will show up in explorer (even Windows explorer once the different volume is selected in Nero).

From there copy it to a drive.

Hope this has been of some help.

The first Link is just a generic guideline for creating Backup's, so it is useless for me.

The second is just a Collection of DVD-Ripping or -Backup Software, unfortunately also useless Sad

Can you make a raw image (bin, cue or iso) of the whole dvd (all tracks)? I remember using a program that could extract files from  those images back in my linux days. I used it with a cd that was unreadable under windows. But i can't remember it's name. When there are no physical errors on the dvd where the files are stored then there must be a solution to rescue the files. Whe you succeed making an image then you can look at it with a hexeditor. Maybe you recognize if your files really where burned.

Andreas

I burned a big zip file to a CD-RW and made an iso image of it. Then pkzipfix the isofile and i got back the zip. So getting files out of an iso should be easy. When the directory is disorted then it is harder and you lose the filenames but it still must be possible.

Andreas

Ha!
Problem solved Cheesy

Solution :
Find out that all the stuff you thought lost, you also forgot to delete off the HardDrive (Alzheimer Deluxe *lol* )

So all is still there, ready for another try to end up on a DVD *g*
