How can I associate a specific sector on a disc with a file?

Postby Phoenix '97 on Sat Apr 29, 2006 9:49 pm

After verifying a compilation (writing data to a DVD), Nero told me:
Read errors from sector 8512 to 8543
How can I determine which files are affected by this? If necessary, I can write the affected files onto another disc.
A couple of years ago I believe I was using some version of Nero 6, and the time that that disc failed, it did actually state which files it had troubles reading. Now that I'm using Nero 7, all it gives me is sector information. Is there a setting somewhere in Nero which tells it to display files?
I realize that not all sectors on a disc will be associated with a file, and instead, the directory structure or something, but by just looking at the relative sizes of the two it's likely a file somewhere that can't be read.

I would suggest doing the following:

At a command prompt:

dir/s/-p X: > files.txt

Where X is the drive letter for the drive of interest.

Are errors reported while doing the dir command?

Get a tool such as ISOBuster (http://www.smart-projects.net/isobuster/), which allow you to look at the sectors and has an option to search for "lost" files.

At worst, you would need to purchase a copy of the ISO 9660 standard and analyze the disk using a tool such as ISOBuster to check sector contents.
