HARD DRIVE DATA WIPING
Software overwrite that sanitizes reusable drives to the NIST 800-88 r2 Clear or Purge level and verifies every drive, returning a per-drive erasure report. Keeps hardware in service for redeployment, resale, or lease return.
Off-Site Data Wiping
Drives are sealed, GPS-tracked, and wiped at a secured facility, then returned or recycled. Verified overwrite to NIST 800-88 r2 with a per-drive erasure report, suited to high volumes handled off-site.
On-Site Data Wiping
Verified overwrite sanitization performed at your facility so drives never leave your control. Sanitizes to NIST 800-88 r2 with a per-drive erasure report, keeping media in service for reuse.

How Hard Drive Degaussing Works
Degaussing erases a magnetic hard drive by exposing it to a magnetic field strong enough to randomize every magnetic domain on the platters, which wipes the stored data and the factory-written servo tracks in a single pass. It satisfies the Purge category of NIST SP 800-88 r2, the current US federal standard for media sanitization, for magnetic media only.
Bottom line: degaussing is a magnetic-media method. It sanitizes spinning HDDs and magnetic tape to the NIST 800-88 r2 Purge level, and it does nothing to SSDs or flash storage, which hold data on chips rather than magnetic platters.
Our degaussing process runs in five steps:
Serialized intake. Each drive and tape is scanned by serial number to open the chain-of-custody manifest.
Coercivity match. We select a degausser whose magnetic field rating exceeds the coercivity of your media, because an underpowered field leaves recoverable data on high-density drives.
Degaussing. Each unit passes through the degausser, which collapses the magnetic field across the entire platter or tape surface.
Verification. We log the cycle against the degausser’s operating record and, for high-assurance programs, follow degaussing with physical destruction of the carcass.
Reconciliation. The serialized manifest is matched against the processed assets and closed with a Certificate of Destruction.
Degaussing is one of the four methods in our hard drive destruction service, alongside hard drive shredding, hard drive crushing, and cryptographic erase. For backup media, see tape degaussing.
Can a Hard Drive Be Used After Degaussing?
No. A modern hard drive is not reusable after degaussing. The magnetic field that erases your data also erases the servo and timing tracks the manufacturer wrote at the factory, and those tracks cannot be rewritten outside a production line. The drive becomes permanently inoperable, which is exactly why NIST 800-88 r2 treats degaussing as a Purge method for end-of-life magnetic media.
Magnetic tape is different. Many LTO and DLT cartridges can be reused after degaussing because the servo data lives in the tape drive, not the cartridge. We confirm the reuse outcome per media type before the job so you can plan replacement hardware. For the full explanation, see can degaussed hard drives be reused.
How Degaussing Compares to Other Sanitization Methods
Degaussing is the fastest way to sanitize large volumes of magnetic media, but it is not a universal method. The table below shows where it fits against the other paths in NIST 800-88 r2.
Method | Works on | Drive reusable after? | NIST 800-88 r2 category | Best for |
|---|---|---|---|---|
Degaussing | Magnetic HDD and tape only | No (HDD), often yes (tape) | Purge | Fast bulk sanitization of magnetic media |
HDD, some SSD via Secure Erase | Yes | Clear or Purge | Drives you intend to redeploy in-house | |
All media (HDD, SSD, tape) | No | Destroy | Highest assurance across every media type | |
Self-encrypting HDD and SSD | Yes | Purge | Encrypted drives that will be reused or returned |
Degaussing pairs naturally with shredding. For classified and high-confidentiality programs, we degauss to Purge, then shred the carcass to Destroy, so the documentation shows two independent sanitization events.
Why Degaussing Does Not Work on SSDs
Solid-state drives, NVMe drives, and flash media store data in NAND cells with no magnetic substrate, so a magnetic field passes through them without changing a single bit. Applying a degausser to an SSD is a documentation failure: the asset reads as sanitized while the data remains fully intact. NIST 800-88 r2 maps flash media to cryptographic erase or physical destruction, never degaussing. For the technical detail, see why degaussing does not work on SSDs, and for the conformant path see SSD destruction.
Which Regulations Degaussing Satisfies
Degaussing satisfies the disposal and sanitization requirements of the major US data-protection regulations when the media is magnetic. The federal standard of record is NIST Special Publication 800-88 Revision 2, published September 2025, which defines the Clear, Purge, and Destroy categories.
Regulation | Requirement | How degaussing satisfies it |
|---|---|---|
Sanitize magnetic media with a method matched to data confidentiality | Degaussing is a Purge-category method for magnetic HDD and tape. | |
HIPAA / HITECH, 45 CFR 164.310(d)(2)(i) | Address the final disposition of electronic protected health information | Degaussing plus a Certificate of Destruction provides the disposal evidence required for a HIPAA audit. |
GLBA Safeguards Rule, 16 CFR 314 | Securely dispose of customer information | Degaussing plus serialized chain of custody satisfies the disposal-program requirement for magnetic media. |
CMMC 2.0 / NIST 800-171, 3.8.3 | Sanitize or destroy media holding CUI before disposal | Witnessed degaussing followed by destruction satisfies the evidence requirement for magnetic media. |
The US Department of Health and Human Services documents how improper media disposal becomes an enforcement matter in its guidance on disposing of protected health information. NIST SP 800-88 r2 is published at nvlpubs.nist.gov.
Service Modes
Degaussing is delivered in four modes. The right choice depends on your custody policy, volume, and audit requirements.
| Mode | Best for | How it is delivered |
|---|---|---|
| On-site degaussing | Media that must be sanitized before it leaves the building | Our operator brings the degausser to your facility and processes media in your view. |
| Off-site degaussing | High-volume magnetic media and lower per-unit cost | Media is sealed, GPS-tracked in transit, and degaussed at a secured facility. |
| Witnessed degaussing | Federal, defense, and classified magnetic media | Your designated employee or auditor observes each degauss cycle in person or by live video. |
| Scheduled program | Recurring data-center and enterprise tape rotation | Monthly or quarterly service with consolidated chain of custody and a master Certificate of Destruction. |
Coverage spans all 50 US states from our seven staffed metros (Dallas, New York City, San Jose, San Diego, Los Angeles, Irvine, Washington DC).

What You Receive
Every degaussing job closes with four documents that form the disposal audit trail.
Serialized Certificate of Destruction. Lists every unit by serial number, the sanitization method, the NIST 800-88 r2 category satisfied, and the date, provided within 24 hours after the destruction event is complete.
Chain-of-custody log. A serialized record of every transfer from intake to degaussing, with per-asset accountability.
Field-strength attestation. Documents the degausser’s magnetic field rating measured against the coercivity of the processed media, proving the Purge was strong enough for that media type.
Asset manifest. The barcoded inventory scanned at pickup, reconciled against the final certificate.
Pricing and Quote Process
Degaussing is quote-driven. Pricing depends on the number of units, the service mode (on-site carries a premium over off-site), whether witnessing is required, your geography, and the media type. The quote is free and carries no obligation, and higher volumes and scheduled tape-rotation programs earn lower per-unit rates.
Per-drive or per-tape pricing for one-time projects.
On-site premium for sanitization before media leaves your site.
Witnessed premium for observed or live-video cycles.
Tiered pricing for scheduled and high-volume programs.
For procurement-driven engagements, we sign an NDA before any job begins. Request a quote or call (866) 850-7977 for project pricing.
Frequently Asked Questions About Hard Drive Degaussing
How do you degauss a hard drive?
A hard drive is degaussed by passing it through a degausser that generates a magnetic field stronger than the drive’s coercivity. The field randomizes every magnetic domain on the platters in one cycle, which erases the data and the servo tracks. We scan each drive into a manifest first, then degauss, verify, and reconcile against a Certificate of Destruction.
Can a degaussed hard drive be reused?
No. Degaussing erases the factory servo tracks along with the data, and those tracks cannot be rewritten, so a degaussed HDD is permanently inoperable. Magnetic tape can often be reused because the servo data lives in the tape drive rather than the cartridge.
Does degaussing work on SSDs?
No. SSDs and flash media store data in NAND cells with no magnetic substrate, so a magnetic field leaves the data intact. Flash media requires cryptographic erase or physical destruction instead.
Is degaussing NIST 800-88 compliant?
Yes. Degaussing is a Purge-category method under NIST SP 800-88 r2 for magnetic HDD and tape. We document the category satisfied on the Certificate of Destruction.
Should I degauss or shred my hard drives?
Degauss when you need fast bulk sanitization of magnetic media and do not need to keep the drive. Shred when you need the highest assurance across mixed media or a visible particle-size standard. Many classified programs do both: degauss to Purge, then shred to Destroy.
How quickly do I receive the Certificate of Destruction?
Within 24 hours after the destruction event is complete. The certificate is serialized, lists every unit, identifies the NIST 800-88 r2 category satisfied, and is delivered by encrypted email and your customer portal.
