If family photographs, documents, music, or project files exist only on CD-R or DVD-R, make a verified copy while the disc and a compatible drive still work. Keep the original disc, but do not treat it as the only backup.

Begin with a visual check of the label side and disc layers. If an intact reading surface needs attention, use the conservative steps in our compact disc cleaning guide before copying. The aim is multiple usable copies plus enough documentation to understand what they contain.

From unknown disc to managed copy

  1. InventoryRecord what the label and case say
  2. InspectKeep damaged media out of the drive
  3. CopyPreserve the complete folder structure
  4. VerifyCheck files, counts, and errors
  5. DuplicateKeep independent copies in different places

Identify what you actually have

Separate pressed commercial discs from writable CD-R, CD-RW, DVD-R, DVD+R, and rewritable formats. Read markings on the disc and case without adding a new label. Record the title, date range, creator, format, and any existing identifier in a spreadsheet or plain-text inventory.

Do not assume handwritten titles describe every file. A disc marked “photos” may include documents, installers, or hidden folders that matter to its context.

Inspect the disc before putting it in a drive

Check the hub, outer edge, reading surface, and label side under angled light. Stop for cracks, warping, peeling layers, wetness, mold, sticky residue, or a full-face label that is lifting. A compromised disc can damage a drive or deteriorate during rotation.

For ordinary dust or fingerprints on an intact disc, use the conservative process in our compact disc cleaning guide. A deep scratch or damaged data layer cannot be cleaned away.

Use a stable computer and known-good drive

Connect the drive on a stable surface where it will not be bumped. Close unnecessary programs and ensure the destination has enough free space. If the drive makes repeated seeking noises, becomes unusually hot, or ejects unpredictably, stop and try a maintained compatible drive rather than repeatedly stressing the disc.

Copy the complete directory structure to a clearly named folder. Avoid opening and resaving every file during the first pass; preserving the source files as received makes later decisions easier.

Verify the transfer instead of trusting the progress bar

Confirm that the copy completed without read errors. Compare file counts and total sizes, then open a sample from each important file type. For a small family archive, this practical check is far better than assuming a folder exists because its name copied successfully.

For higher-assurance work, create checksums with a maintained tool and retain the manifest beside the files. A checksum can reveal whether a file changes later, but it does not prove that the original file was healthy or meaningful.

A copied folder is not yet a preservation system

Place the verified files on at least two separate storage devices or services, with one copy kept in a different location. A synced folder alone may reproduce accidental deletion, so understand whether the service retains versions and deleted files.

The U.S. National Archives emphasizes managed storage and backups when reformating audiovisual holdings. The useful principle for a home archive is active stewardship: check copies periodically, replace failing storage, and migrate before the required hardware disappears.

Keep context with the files

Add a short readme that states who created the disc, what it appears to contain, when it was copied, the source label, any read errors, and where other copies are stored. Preserve folder names unless they expose sensitive personal information in a shared location.

If a disc contains software or unusual file formats, record the operating system or application named on its packaging. Do not install unknown programs merely to test them; cybersecurity review is separate from media preservation.

Store the original after copying

Return the disc to a clean case that supports it at the hub and store it upright in a stable, cool, dry, dark room. Do not attach a migration note to the disc surface. Put it in the case or inventory. Our guide to protecting the CD label side explains why pressure and adhesives are risky.

Retaining the original may preserve evidence, artwork, or files missed during the first transfer. It also provides another source if a copy was made incorrectly. The digital copies, however, are what allow ongoing verification and migration.

Cases that need specialist recovery

  • The disc contains the only copy of unique or legally important material.
  • It is cracked, delaminating, mold-affected, or rejected by more than one known-good drive.
  • Copying produces repeated errors or incomplete files.
  • The content depends on obsolete software, encryption, or specialized hardware.
