CDmage is a software utility, which performs different tasks with a common CD image files on your harddrive. The most-wanted being: scanning, repairing and extracting.

1. Image scanning
A: It checks sectors against corruption. There are rules defined by ISO standards, which must be followed by each sector of the CD. Other programs can perform similar checks as well, namely well known BINChunker and Fireburner. CDmage displays all corrupted sectors along with a description of each error found.
2. Image errors
CDmage can repair image errors, but not all errors can be repaired. CDmage uses a similar mechanism for repair as CD writer/reader does. It uses Error Correction Code fields (ECCP&ECCQ) of the sectors.

Safety of repairing corrupted sectors with CDmage
The repairing of corrupted sectors is 100% safe if corruption isn't intentional. Repaired sector is exactly like it's original. Please note than not all image errors should be repaired. There are intentinal errors which are part of some copy protection schemes. Some CD ripping apps (CloneCD, BlindRead...) let you make working copy of your legally owned software. If copied software is copy protected, then it's image files can contain intentional corruptions. Repairing of them would cause a non-working copy when burned.
