Recovering Data from a Bad Burn

So, I had a DVD+RW with about 850MB of data on it, and when i burned it, i told it not to finalize.

Then, yesterday, I decided i wanted to write more to it. Multisession, you know? So I hit up CDBurnerXP, and add files to burn.

CDBurnerXP crashes while I'm away from teh computer, and now the disc is unreadable.

I've tried ISOBuster, CD/DVD Diagnostic, and Stellar Phoenix. None of them seem to work.

Isn't the FAT the first thing a burner writes to the CD? If so, why can't it read the first session on the disc at all? If not, that's just hard gay.

$ cat /dev/sda1 > cd.iso

NO you don't use cat for copying filesystems you utter tard.

dd?

dd if=/dev/sda1 of=cd.iso

does the same as cat.

So ... there's nothing i can do, then?

Don't listen to these guys who are trying to make everything confusing or hard. All you have to do in this situation is go to http://www.isobuster.com/ and download isobuster. Put the DVD in the DVD drive, run ISObuster, select the session you want and extract the files to any drive you want on your HD, then reburn them to a new DVD. Simple. As. Pie.

Let no confusing code junkies stand in your way.

READ MY FIRST POST:

"I've tried ISOBuster, [and other software]. None of them seem to work."

Then you're screwed.

not exactly. dd shows read/write errors. cat does not.
