Make sure the read side of the dvd is clean and free from scratches. There are scratch removers.

Are you using FAT32 for your Windows installation? While the above answers may be correct I am wondering if the files are larger than 4GB and you are using FAT32, which can't handle files larger than 4GB.

I'm always using FAT32 as windows installation partition. Previously I could open & run that DVD. But since some days, I cant copy all the files of that DVD. I've checked that DVD, and there are no scratch marks distinguishable. Please help me to recover that data...

Thank you guys. Special thanks to "clive_pearce" for that unique tool for recovering bad sector data, and thanks to "Kuwese" for CD/DVD scratch recovering technique!

After 14 hours waiting, I have recovered all 4.14GB data from my data DVD! Scratch recovering technique and 'Roadkil's Unstoppable Copier' greatly helped me!!

In the future don't work with files larger than 4GB in FAT32. That is probably why is was corrupted in the first place.

But I worked with larger than 4GB DVD in FAT32 partition. Some times this problems occurs, and especially in DVD. I have other partition in NTFS, but system partition is in FAT32. Is NTFS better than FAT32? Ok, next time of formatting my pc, I will make all partition in NTFS...

One of the shortcomings of FAT32 is the 4GB file size limitation. Also creates a lot of slack space on large hard drives. See the chart below showing default cluster sizes. One file of any size will use a full cluster. So, if you have a 2kb file and it uses 32kb there is lots of wasted space.

Cluster sizes

for FAT32 are as follows:
512MB to 8,191MB = 4KB
8,192MB to 16,383MB = 8KB
16,384MB to 32,767MB = 16KB
Larger than 32,768MB = 32KB

NTFS - All partitions on a PC = 4KB default

OK, next time of formatting the system partition, I'll use NTFS. Thank you... (perhaps I could understand the problem :)
