I have a Dell Diagnostic CD that I extracted to an ISO file using ISOBuster. I then used ISOBuster to extract an individual file I needed to modify. It was a .BAT file, if it makes any difference. After making the necessary modifications to the .BAT file, I then opened the extracted ISO image in MagicISO, deleted the old .BAT file, added my modified version of the file, and then saved the ISO image. I used MagicISO for this because ISObuster apparently does not allow you to add/remove individual files from an ISO image. I then burned the modified ISO image to a CD-R using Nero. The burn process and verification both completed without errors, yet when I tried to read the burnt CD in windows explorer, I received the following error message:

"Windows cannot read from this disk. The disk might be corrupted, or it could be using a format that is not compatible with Windows."

If I browse the burnt CD in ISOBuster or MagicISO, there are no files present. I tried burning this image to one CD-R and three CD-RWs, and received the same error message every time. The drive has no problems reading other discs.

Does anyone know what the problem could be?

Welcome to the forum

A possibility is that you are using a low quality disc so the drive is not able to read it because of the too many errors.

Try using a better disc and see if this solve

The CD-R's are Verbatim, and the CD-RW's are TDK. They aren't TY's, but I've never had a coaster from them before.

oops... at least we excluded the most frequent cause of an unreadable disc

Another possibility is that you saved the ISO file changing some parameter so the file is not more compliant with windows. Another possibility is that changes in the .bat files contain some error that cause this issue.

At the moment I can't think to other possibilities, sorry

If I extract the ISO image with WinISO, extract the .BAT file with WinISO, add the .BAT file back to the ISO with WinISO, and burn the ISO image to a CD with WinISO, then everything works fine.

Apparently WinISO isn't fully compatible with Nero and/or Isobuster.
