How to Use CDRoller
Basic Workflow
- Insert the damaged disc into the optical drive.
- Launch CDRoller; the software will automatically detect the disc and attempt to read the file system.
- If the file system is corrupted, click “Find Lost Data” to perform a deep scan for recoverable files.
- Browse the list of recoverable files (preview available for many file types).
- Select files and click Recover to save them to another drive (avoid saving back to the same damaged disc).
Additional Options
- Session Selection: For multi-session discs, choose which session to scan.
- Read Retries: Configure the number of read retries for difficult sectors (more retries may recover more data but will take longer).
- Skip Bad Sectors: Option to skip unreadable sectors and continue.
Important Notes
- CDRoller is a commercial product with a free trial that allows you to preview recoverable files but not save them.
- It is particularly useful for recovering photos, videos, and documents from DVD-VR and AVCHD discs.
- Windows-based, but runs well on Linux/macOS via Wine.
- Always recover data to a different drive to avoid overwriting the source.
- Success depends on physical damage extent; the software cannot repair physical scratches but can work around them using advanced read logic.
