Having a hard drive shredded: cost, process and proof of data destruction

3 July 2026 · 15 min read · DeSnipperaar

Having a hard drive shredded is the only way to be sure your data is really gone. Wiping or formatting often leaves data behind that free software can make readable again. With data shredding the drive is physically ground into particles, so recovery is impossible. This article explains what it costs, how the collection service works, which level you need and what data destruction certificate you end up holding.

Old laptops, servers and loose hard drives pile up in almost every organisation. They often sit in a cupboard for years because nobody knows quite how to dispose of them safely. That is a risk, because those drives hold customer data, personnel files, passwords and business secrets. As long as the drive exists, the data exists. Having a hard drive shredded removes that risk in one go. Below we explain what data shredding actually involves, why it is more reliable than software, what it costs and how to prove it was done properly.

What does having a hard drive shredded mean?

Shredding means the hard drive is fed through an industrial shredder that reduces the metal and the memory chips to small particles. What remains is a pile of metal fragments in which no sector or chip is intact. This is physical data destruction, as opposed to logical destruction such as wiping or overwriting. With data shredding nobody can read the drive any more, not even with advanced forensic equipment. The term data destruction is often used as an umbrella for all methods, but shredding is the most definitive form. Where wiping depends on software that has to execute everything correctly, a shredded drive is simply no longer a drive.

Why wiping or formatting is not enough

Formatting a drive or emptying the recycle bin feels final, but it is not. With an ordinary deletion only the reference to the file is removed, while the data itself stays on the drive until it is overwritten. With free recovery tools that data is often back within minutes. Even a full format leaves remnants in many cases. Professional overwriting to a standard can work for ordinary hard drives, but it is error-prone. A drive with bad sectors, a drive that no longer boots or an SSD with smart memory management can never be wiped with certainty. That is why physical shredding is the safest choice. We discuss the difference between the two methods in detail in wiping versus destroying a hard drive.

Shredding, degaussing or wiping: the methods compared

There are three main methods for removing data from a hard drive. Each has its own use and reliability.

Method	How it works	Certainty
Wiping / overwriting	Software writes new data over the old	Moderate, fails on bad drives and SSDs
Degaussing	Strong magnetic field wipes magnetic drives	Good for HDD, does not work on SSD
Shredding	Drive is physically ground into particles	Highest, works on any carrier

Degaussing is a fine technique for classic magnetic drives, but it leaves the drive intact in appearance and gives no visible proof. On top of that degaussing has no effect on SSDs, because they use no magnetic platters. Shredding works on any carrier and delivers an immediately visible result. For most organisations having a hard drive shredded is therefore the simplest and most defensible choice.

Which DIN level do you need for hard drives?

Like paper, data destruction has standardised levels. The DIN 66399 standard describes the so-called H-classes for data carriers, where H stands for hard drives. The higher the number, the smaller the particles and the higher the certainty.

Level	Maximum particle size	Suitable for
H-3	Coarser particles	Ordinary business data, low risk
H-4	Small particles	Personal data, the workable minimum
H-5	Very small particles	SSDs, social security numbers, medical and special data

For most businesses H-4 is the right level for classic hard drives. If you work with special personal data or want to destroy SSDs, choose H-5. The memory chips of an SSD are small, so they have to be ground more finely to make every fragment unreadable. More on the levels and what they mean is in DIN 66399 explained.

What determines the cost of shredding hard drives?

The question asked most is what data shredding costs. The honest answer is that the price depends on a few factors. Once you know them, you can compare quotes properly and know in advance where you stand.

• The number of drives. You pay per item, and the price per drive falls at larger numbers.
• The level. H-5 requires finer grinding than H-4, which can be slightly more expensive.
• The type of carrier. A loose 3.5-inch drive shreds differently from an SSD, a server or a whole laptop.
• The distance. Within 20 km of Amsterdam we charge no call-out fees.
• Combination with paper or other carriers. Together in one collection saves the call-out.

What matters is that an honest provider charges per item by serial number and gives a fixed price in advance. That way you know exactly what you pay before anything happens. The general make-up of data destruction costs resembles that of paper, which we explain in archive destruction cost.

A price indication with worked examples

To give a sense of it, here are three typical situations. The exact price depends on your number and level, so always request a quote for a fixed price.

Situation	Number of carriers	What plays a part
Individual or sole trader	1 to 3 drives	Small order, possibly collected together with paper
SME office	10 to 30 drives	Lower price per item, one collection moment
Lease return or migration	50 drives or more	Sharpest price per item, planning on site

If you have only one or two drives, it is often economical to have them taken along during a paper collection or together with other data carriers. That way you pay for the call-out only once. At larger numbers the price per drive falls, because the collection and the admin spread across more items.

HDD versus SSD: why the difference matters

A classic hard drive, the HDD, stores data on spinning magnetic platters. An SSD stores data in memory chips with no moving parts. That difference matters for destruction. An HDD is made unreadable well with degaussing or coarse shredding. An SSD is not, because the chips are small and the data is spread across the memory with techniques that are not predictable from the outside. That is why an SSD must be ground more finely, at level H-5, so every chip breaks apart. If you wipe an SSD with software, wear levelling can leave part of the data beyond the reach of the wipe command. We explain why in destroying SSDs, why wiping does not work.

How the collection service works

Having a hard drive shredded need not be a hassle. The collection service works in a few clear steps.

1. You request a quote with the number of carriers and the level you want.
2. We schedule the collection at your location, at a time that suits you.
3. The carriers go in a sealed bin, under a registered handover.
4. The drives are shredded to the agreed DIN level.
5. You receive a certificate with the serial numbers of all destroyed carriers.

The whole chain is closed, from your door to the shredder. How that so-called chain of custody works and why it matters for your burden of proof is in our explainer on data destruction. The point is that every carrier stays traceable until the moment it is destroyed.

The shredding process, step by step

At the actual destruction the drives are registered one by one by serial number and then fed into the shredder. The shredder consists of heavy blades that tear apart the metal and the circuit boards. What comes out is a mix of metal particles that forms no recognisable drive any more. That material then goes to a metal processor, where the raw materials are recovered. So data shredding combines maximum security with responsible recycling. The difference with shredding paper lies mainly in the force needed, because metal and chips require much heavier machines than paper. We describe the background of the shredding process in how a hard drive is shredded.

The data destruction certificate

The proof that everything went well is the data destruction certificate. It states the date, the DIN level applied and the serial number of every destroyed carrier. That serial number is the difference with a paper certificate, because it ties the proof to your specific drives. So in an audit or an inspection you can show that exactly that drive was destroyed. Keep the certificate with your GDPR records, so you can show it when needed. What belongs on such a certificate is in data destruction certificate explained.

Demonstrable destruction for the GDPR

The GDPR asks not only that you destroy personal data, but also that you can demonstrate it. A hard drive lying in a drawer is not destruction, even if nobody uses it any more. Only once the carrier is irreversibly destroyed and you have a certificate for it do you meet the requirement of demonstrability. For businesses that handle customer or patient data this is no formality but a legal duty. A shredded drive with a certificate is the conclusive proof that you take your duty of care seriously. If a data breach involving old hardware ever comes to light, the certificate shows that particular drive had long since ceased to exist.

Having hard drives shredded in Amsterdam and surroundings

We collect data carriers within a 20 km radius of Amsterdam, with no call-out fees. Whether you are in Amsterdam-Noord, Amstelveen, Zaandam, Diemen or Haarlem, we come to you. A local data shredder in Amsterdam means short lines and fast planning. You do not have to drop off the drives yourself or put them in the post, which is unwise with sensitive data anyway. The carrier stays under sealed handover until it is destroyed. For anyone outside the immediate region, collection is possible nationwide via pooled routes. Give your postcode with the request, and you will know straight away whether you fall within the service area with no call-out fees.

Common situations

Having a hard drive shredded comes up at various moments. The most common situations are these.

• End of a lease. Before hardware goes back, the drives must come out and be destroyed.
• Equipment replacement. In a migration to new systems, old drives are left over.
• Faulty drives. A drive that no longer boots cannot be wiped, but it can be shredded.
• Office clear-out. In a move or clear-out, forgotten carriers often surface.
• End of retention period. Data you no longer need to keep should be destroyed.

In all these cases the same principle applies. As long as the drive exists, the data is a risk. So have the carriers gathered and collected and destroyed safely in one go.

Shred it yourself or have it shredded?

Some people consider destroying a drive themselves with a drill or a hammer. It feels satisfying, but it is not a reliable method. Drilling a few holes leaves large parts of the magnetic platters intact. Those can still be read with the right equipment. On top of that you have no proof at all that the data is gone. A professional shredder grinds the whole drive into particles and provides a certificate with it. For an organisation that must comply with the GDPR that is the difference between a feeling of safety and demonstrable safety. Doing it yourself can at most be an addition, never a replacement for professional data destruction.

What do you do with the drive until collection?

There can be time between when you retire a drive and the collection. Keep the carriers in a safe place during that period, for example in a locked cupboard or drawer that not everyone can reach. Keep a simple list of the serial numbers, so at collection you can check that everything goes along. Do not put the drives with the ordinary waste and do not hand them to a random collector, because then you lose control. A sealed collection bin in the office works well if carriers come free regularly. That way you keep the chain closed from the moment of retirement to destruction.

Environment and recycling after shredding

A common concern is whether shredding is responsible for the environment. It certainly is. After grinding, the metal particles are separated and recovered by a metal processor. The steel, aluminium and the precious metals from the circuit boards get a second life as raw material. So secure data destruction goes hand in hand with circular processing. You do not have to choose between security and sustainability, because shredding delivers both. The drive is unreadable and at the same time the material is not wasted. That is a more pleasant end picture than a cupboard full of old hardware slowly ageing while nobody does anything with it.

On-site shredding or after collection?

Many organisations ask whether the drives are destroyed at their own location or only later at a fixed processing site. Both models exist. With destruction on site a shredding truck comes to you and you watch it happen, which is a requirement for some sectors. With the usual collection service the carriers go along under sealed and registered handover and are destroyed at a secure location, after which you receive the certificate with serial numbers. For most businesses that second model is sufficient, because the chain is closed and every carrier stays traceable until destruction. If you definitely want to be present, say so with the request, and we tailor the approach to that. The certainty lies not in where the shredder stands, but in the closed chain and the proof afterwards. A data shredder in Amsterdam with short arrival times makes both variants practical.

Which other data carriers can come along?

A hard drive is not the only carrier with sensitive data. In the same collection other data carriers can come along, so you handle everything in one go. Think of SSDs and NVMe modules, USB sticks and memory cards, old backup tapes, CDs and DVDs through to whole laptops and phones. All these carriers are registered per item and destroyed to the right level. The advantage of combining is that you pay for the call-out only once and get a single certificate listing all the volumes. That stops a forgotten USB stick or phone with business data on it from being left somewhere. Before the collection make a short inventory of everything that holds data, so nothing accidentally goes back in the cupboard. Data destruction is only complete when every carrier has been taken, not just the obvious hard drives.

Common mistakes

• Only wiping and thinking it is done. Without physical destruction a risk remains.
• Keeping faulty drives. Those are exactly the ones you cannot wipe, so have them shredded.
• Keeping no serial numbers. Without a list you cannot check afterwards what was destroyed.
• Destroying an SSD at too coarse a level. Choose H-5, so the chips really become unreadable.
• Not keeping the certificate. Without proof you can demonstrate nothing in an inspection.

Step by step to safe destruction

1. Gather the carriers in a locked place and note the serial numbers.
2. Decide the level, H-4 for HDD or H-5 for SSD and special data.
3. Request a quote with the number and type of carriers.
4. Schedule the collection at your location within the service area.
5. Keep the certificate with your GDPR records.

An example from practice

Suppose an IT manager at an SME replaces twenty laptops and also has a box with five old servers and a handful of loose drives left over. Some of the drives no longer boot, so wiping is not an option. The manager gathers all the carriers in a locked cupboard and notes the serial numbers. He requests a quote for data shredding at level H-5, because there are SSDs among them. Within a working day there is a fixed price per item, with no call-out fees because the office is in Amsterdam. On the agreed day all the carriers go along in a sealed bin. A few days later the certificate is in the inbox, with each serial number neatly listed. The manager files it with the GDPR records. The cupboard is empty, the risk is gone and everything is demonstrably in order.

Frequently asked questions

What does it cost to have a hard drive shredded?

The price depends on the number of drives, the level you want and whether other data carriers or paper come along. You pay per item by serial number, with a fixed price in advance and no call-out fees within 20 km of Amsterdam.

Why is wiping or formatting not enough?

After wiping or formatting, data can often still be recovered with standard software. Shredding destroys the drive physically, so the data is irreversibly gone.

Which level do I need for a hard drive?

For ordinary business drives H-4 is the workable minimum. For SSDs and special data H-5 is the right choice, because the memory chips are then shredded more finely.

Do I get proof the drive was destroyed?

Yes. You receive a data destruction certificate with the date, the level applied and the serial number of every destroyed drive.

Can I have a faulty drive shredded?

A faulty drive is exactly the kind you are better off having shredded, because wiping no longer works if the drive will not boot. Shredding works regardless of the state of the carrier.

Can paper and drives come in one collection?

Yes. Paper and data carriers can be collected together, so you pay for the call-out only once and get a single certificate for both volumes.

Conclusion

Having a hard drive shredded is the most certain way to destroy data irreversibly. Wiping and formatting leave remnants too often, and degaussing does not work on SSDs. With physical shredding at the right DIN level you know for sure no sector or chip is readable any more. You pay per item by serial number, with a fixed price in advance and no call-out fees within the service area. The data destruction certificate makes it demonstrable afterwards that exactly your drives were destroyed. So data shredding combines maximum security with conclusive proof and responsible recycling.
