k3b and disk burn error
Hello. This is my first time posting on a forum. I could not actually find any info on my problem on google or anything because I don't know what to call it.
I am using Debian and k3b to burn a CDs. The first disk I write, I "verify written data". This disk checks out okay. Nothing wrong with it at all.
The second (and all following disks) I do not choose "verify written data". I had assumed that since it worked the first time, it should work each time afterward. However, when I went to try this disk (after erroroneously deleting all material that was burned to the disk), it would not work. Debian would not mount it. It said that it does not have a valid fs type.
I also tried to dd if=/dev/hdd of=/home/user/iso.iso
This was likewise fruitless.
It seems that all disks I choose to "verify written data" work fine. If I do not, it seems to have no file system.
My question: how can I recover the data from those disks burned, or even repair the disks themselves (preferable).
It should be noted that Windows2000 and XP on different CD drives and different computers also did not find this disk.
Thank you all very much.
