CDs and DVDs: keep or destroy? The choice at home

5 July 2026 · 12 min read · DeSnipperaar

Almost every home still has a drawer full of CDs and DVDs. Holiday photos on a burned disc, a backup of the old computer, films you no longer play. When you clear out, the same question keeps coming back. Which discs do you keep and which can you throw away? And if they hold personal data, how do you really get rid of it? This article helps you make that choice: first how to store the discs you want to keep, then how to destroy the rest safely.

It comes down to two different goals. Discs you want to keep should stay readable as long as possible, so they need good storage. Discs with sensitive data that can go must become unreadable, and that is harder than most people think. Breaking a CD in half feels final, but it often is not.

Why old discs still hold data

A CD or DVD is essentially a slab of transparent plastic with a layer inside that holds the data. On a pressed film the data sits in microscopic pits, on a home burned disc in a dye layer that the laser has altered. In both cases the information stays physically present as long as that layer is intact. As long as a disc is readable, someone can simply restore the photos, documents or backups onto a computer. A box of old discs is therefore just as much a store of data as an old hard drive. That is exactly why the choice between keeping and destroying is more than tidying up.

Keep or destroy: how to make the choice

Start by sorting on content, not on age. Go through the discs and split them into three piles. The first pile holds discs with precious or unique content you want to keep, such as family photos or home video. The second pile holds discs with personal or sensitive data that can go, such as old tax backups, scans of documents or bank statements. The third pile holds discs with no personal content at all, such as bought music albums or feature films.

That split decides everything. The first pile you will store well. The second pile you have safely destroyed. The third pile you can give away, sell or recycle. The tricky ones are the borderline cases, and for those a simple rule applies. If there is anything personal on it and you do not want to keep it, treat the disc as the second pile.

How to store the discs you want to keep

For the discs you want to keep the goal is simple. They should still be readable in ten or twenty years. Optical discs do not last forever, but with the right storage you can extend their life considerably. The three biggest enemies are heat, moisture and light. A disc that sits in the attic for years, where it gets hot in summer, degrades faster than a disc in a cool cupboard inside the house.

The key rules of thumb at a glance:

• Store upright, just like a book on a shelf. Stacked flat, discs can start to warp, which makes them harder to read over time.
• Cool and dry, ideally at room temperature without big swings. Avoid the attic, the garage and the windowsill.
• Dark, out of direct sunlight. Home burned discs in particular are sensitive to UV light.
• In a sleeve or case, so no dust or scratches reach the surface.
• Hold by the edge, with a finger through the hole. Fingerprints on the reading surface attract dust and can cause scratches.

You clean a dirty disc with a soft dry cloth, wiping straight from the centre to the edge. Never wipe in circles, because a circular scratch follows the exact track of the data and does more damage than a straight one.

What disc rot actually is

The creeping enemy of old discs is called disc rot. The data layer or the thin reflective layer oxidises or comes loose, often from the edge inward. You recognise it by small transparent spots, discolouration or a bronze or copper sheen when you hold the disc up to the light. Wherever disc rot strikes, the disc becomes unreadable, and that is irreversible. Cheap burned discs from the early days are more prone to it than pressed factory discs. Good storage slows the process, but it cannot stop it entirely.

Copy what you truly do not want to lose

That is why a golden rule applies to truly valuable content. Never rely on a single optical disc as your only copy. Move the photos or videos you do not want to lose onto a modern medium, such as an external hard drive or a secure cloud service. Do that while you still can, because once disc rot sets in it is too late. Once the content is safely stored elsewhere, the old disc changes from an irreplaceable backup into something you can clear out. And if it holds personal data, that disc then belongs with the pile you have destroyed.

The pile that can go: why breaking is not enough

Now for the discs you want to get rid of. Many people think breaking a disc in half solves the problem. It feels thorough, but it is not. A broken disc consists of two halves with large, intact reading surfaces on each side. With adapted equipment a considerable part of the data can still be recovered. For a holiday film that makes no difference, but for a backup with your bank details or copies of your passport it does.

The same goes for other do it yourself tricks. The microwave does damage the disc, but it produces a lot of smoke and stench from burning layers and can damage your appliance. Cutting through a CD with scissors works physically, but it leaves large readable pieces. None of these methods gives you certainty that the data is really gone.

Does scratching a CD make it unreadable?

This is perhaps the most stubborn misconception. Scratching the top of a CD does not make the disc unreadable. In fact the fragile reflective layer sits just under the printed top, while the laser reads from below. A few scratches with a key catch the label, but the data layer stays largely intact. Even heavily scratched discs can often still be read partly with special equipment or after polishing. Scratching reduces readability a little, but it is not destruction. For discs with personal data it is simply not safe enough.

Safe destruction: granulating to a DIN level

Real destruction means the disc does not split in two but falls apart into a handful of small particles. An industrial shredder for optical discs cuts the CD or DVD into pieces of a few millimetres, so small that no readable track remains. The standard DIN 66399 sets out a separate O scale for this, from coarser pieces to very fine particles. For ordinary personal data from a household a common O level is more than enough. Only at that particle size is the content unrecoverable, and that is exactly the difference with breaking or scratching. How that works technically is covered in our article on destroying CDs, DVDs and Blu-rays.

Professional destruction from home

You do not need to buy a shredder yourself for this. For a few discs that is not necessary either. You collect the discs from the second pile in a box, and it is collected at your home. Within 20 kilometres of Amsterdam we charge no call-out fees, and beyond that we work with pooled routes so it stays affordable nationwide too. The discs are destroyed into particles and you get the certainty that the data is unrecoverable. You agree the price in advance, so you know where you stand.

Combine discs with other items

The big advantage when you are clearing out at home anyway is that you can bundle everything. A box of CDs does not need to go separately. You hand it over in one collection together with the other things you want to dispose of safely. Think of old USB sticks and memory cards, a discarded phone, old bank cards, copies of documents and stacks of paper. Our article on disposing of USB sticks and memory cards explains how this works for small data carriers. Whether you choose the whole clear out at once or just the discs, the idea stays the same. What is part of archive destruction for individuals can come along in the same trip. A broader overview of the subject is in our article on data destruction.

The proof: a certificate of destruction

Professional destruction comes with a certificate of destruction. It states when destruction took place, how much and at what level. For a household this is rarely required, but it does give peace of mind. You have it in writing that your old backups and documents really were made unreadable. If you work from home and keep client data, for example, that certificate is valuable as proof. What exactly belongs on such a document is explained in the data destruction certificate explained.

Recycling after destruction

After granulating, the disc is still material. The plastic particles go to material recycling, so the raw material gets a second life. That combines safety with sustainability. If you have discs from the third pile with no personal content at all, such as bought music or films, they can go straight to a recycling point with the hard plastic or a collection point. Try not to throw empty discs loose into the general waste, because the material is easy to reuse.

What does destruction cost?

For a private person it is modest. You pay a fixed price per box, with the certificate included if you want it. Because you can combine the discs with other material in the same collection, you spread the cost of the trip across everything that goes along. A box of CDs, a few USB sticks and a stack of paper in one go is therefore cheaper than arranging everything separately. Within 20 kilometres of Amsterdam there are no call-out fees. You agree the price in advance, with no surprises afterwards.

Sorted in five steps

1. Sort your discs by content into three piles: keep, destroy and simply give away.
2. Copy precious photos or videos from the keep pile onto a new medium.
3. Collect the discs with personal data in a box, together with other items if you like.
4. Have it collected and granulated into particles, at a fixed price in advance.
5. Keep the certificate as proof and store the keep discs neatly.

Common mistakes

• Relying on a single disc. A unique photo on one burned CD can be lost to disc rot.
• Seeing scratching or breaking as destruction. The data then stays partly readable.
• Stacking discs flat in a hot attic. That speeds up warping and disc rot.
• Throwing personal backups in the general waste. Unshredded, your data stays accessible.
• Throwing discs away separately from the rest. Combining in one collection is safer and cheaper.

An example from home

Say you tidy the utility cupboard and find a shoebox full of discs. A few hold family photos, some are old computer backups with tax returns on them, the rest are bought films. You move the photos onto an external drive and the cloud. The backups with personal data go in a box, together with an old phone and some paper that had to go anyway. You have that collected and destroyed in one go, with a certificate. The films you set aside to give away. One afternoon of work, and your old data is safely gone while your memories are preserved.

Frequently asked questions

Does scratching a CD make it unreadable?

Not reliably. Scratching the top often only damages the label, while the data under the reflective layer stays intact. A scratched disc can still be read with special equipment, so for sensitive data scratching is not safe destruction.

How do I store CDs and DVDs so they do not degrade?

Store discs upright in their case, cool, dry and out of direct sunlight. Hold them by the edge and the centre hole, not on the surface. That slows disc rot and scratches the longest.

How do I safely destroy an old CD with personal data?

Have the discs granulated or shredded into small particles according to the DIN 66399 O classification. That makes the data unrecoverable, unlike breaking in half. You can have a box of discs collected together with other items.

Can I throw CDs and DVDs in the general waste?

Empty discs belong with hard plastic or a recycling point, not loose in the general waste. But as long as they hold personal data you should destroy them first and recycle afterwards.

How long do CDs and DVDs last?

It varies a lot. Well stored pressed discs can last decades, while cheap burned discs can show disc rot after only a few years. Copy valuable content onto a new medium in good time.

Conclusion

Clearing out old CDs and DVDs comes down to one clear choice per disc. If you want to keep the content, store the disc upright, cool, dry and dark, and copy what is precious onto a modern medium before disc rot sets in. If there is anything personal on it that can go, do not rely on scratching or breaking. Those leave the data partly readable. Have such discs granulated into particles, ideally in one collection together with other things you want to dispose of. That way you keep your memories safe while your data truly disappears.
