What Is DVD-RW Extraction?

DVD-RW is a rewritable optical format used for data storage and video. Extraction requires attention to the disc structure and any sessions or rewrites.

DVD-RW media

DVD-RW should be assessed before extraction because its recording history and filesystem may affect what can be recovered.

Data and video structures

Preserve the source state during examination and record any visible labels or identifiers.

Filesystem recovery

Where the disc structure matters, retain an image as well as extracted files.

Verification

Check that extracted files open correctly and compare expected and recovered content.

Preservation

Record checksums and any unreadable areas.
