Certified Data Erasure for Hard Drives, SSDs, and Enterprise Tape Media
When storage devices leave your environment, the data on them does not disappear on its own. Proper data erasure is a deliberate, documented, and verifiable process — and it is one of the most important steps in any IT asset retirement program.
DES Technologies provides certified data erasure services for hard drives, solid-state drives, and enterprise tape media. Every project is performed in alignment with recognized industry standards, backed by complete audit documentation, and supported by a secure chain of custody from intake through completion.
Whether you are retiring a single workstation or decommissioning an entire data center, DES gives you the confidence that your data has been permanently removed — and the documentation to prove it.
What Is Data Erasure?
Data erasure — also called data wiping or data sanitization — is the process of permanently overwriting all existing information on a storage device so it cannot be recovered by any known forensic method.
It is not the same as deleting files or formatting a drive. Those methods leave data intact at the sector level and are recoverable with widely available tools. Certified data erasure targets every addressable location on the media and uses verification passes to confirm the data is gone.
When performed correctly, data erasure allows storage devices to be safely redeployed, remarketed, or recycled — without exposing sensitive information.
Why Data Erasure Cannot Be an Afterthought
Improper disposal of storage media is one of the most common — and most preventable — causes of enterprise data breaches. The consequences are real: regulatory penalties, legal liability, reputational damage, and loss of customer trust.
Organizations across healthcare, finance, government, education, and enterprise IT face increasing pressure to demonstrate that sensitive data was properly handled at end of life. Auditors, regulators, and security teams all require documented evidence — not just good intentions.
DES Technologies exists to make that documentation easy, defensible, and complete.
Our Data Erasure Services
Hard Drive Data Erasure (HDD & SSD)
Hard drives are among the most common sources of data exposure when retired without proper sanitization. DES provides certified erasure for both traditional hard disk drives (HDDs) and supported solid-state drives (SSDs).
We use KillDisk® enterprise-grade software to perform sector-by-sector overwriting with full verification passes. Each erasure is tied to the device’s serial number and asset tag, creating a traceable, auditable record for every unit processed.
Our hard drive erasure process includes:
- Sector-by-sector overwriting
- Post-erasure verification passes to confirm successful data removal
- Serialized erasure reports per device
- Routing of failed devices to physical destruction to maintain compliance
Enterprise Tape & LTO Media Data Erasure
Tape media presents challenges that most IT teams are not equipped to handle internally. Volume, format complexity, and tracking requirements all demand a specialized approach.
DES offers secure data erasure for LTO cartridges and enterprise tape formats, using a two-pass full erase method designed to overwrite all data across the entire length of each tape. Every tape asset is logged from intake through completion, with unique identifiers maintained throughout the process.
Degaussing and Physical Destruction
In some cases, data erasure alone does not meet your compliance requirements. Device condition, risk classification, or regulatory mandate may call for a more definitive method.
For those scenarios, DES also offers magnetic degaussing and physical destruction. Degaussing permanently neutralizes the magnetic field on media, rendering it completely unreadable and unusable. Physical destruction takes it further, eliminating the device entirely.
Our team evaluates each situation and recommends the appropriate method — erasure, degaussing, or destruction — based on your security requirements and asset lifecycle goals.
Supported tape formats include:
- LTO tape cartridges (all generations)
- IBM 3592 enterprise tape
- Other enterprise magnetic tape formats
NIST 800-88 Compliance
What NIST 800-88 Means for Your Organization
NIST Special Publication 800-88, Guidelines for Media Sanitization, is the authoritative federal standard for secure data destruction. It defines three levels of sanitization — Clear, Purge, and Destroy — and provides specific guidance for HDDs, SSDs, tape media, and other storage types.
Compliance with NIST 800-88 is required or strongly recommended for:
- Federal agencies and government contractors
- HIPAA-covered entities in healthcare
- Organizations subject to FISMA, DFARS, or CMMC
- Any enterprise with a formal data governance or security program
DES Technologies performs hard drive and tape erasure in full alignment with NIST 800-88 Clear and Purge guidelines. All processes are also compatible with DoD 5220.22-M overwriting methods.
DES Technologies is a Phoenix Certified ITAD provider. Phoenix Certification verifies that our data sanitization processes, documentation practices, and security controls meet the rigorous requirements of NIST SP 800-88.
Chain of Custody and Audit Documentation
Every data erasure project at DES includes complete documentation from the moment assets arrive to the moment the project closes.
Your documentation package includes:
- Device intake logs with serial numbers and asset tags
- Erasure verification reports per device
- Pass/fail status with disposition records for failed units
- Certificates of Data Destruction where required
- End-to-end chain of custody records
This documentation is designed to satisfy internal governance requirements, regulatory audits, and third-party assessors. You will always be able to demonstrate exactly what happened to every device.
Frequently Asked Questions
What is the difference between data erasure and data destruction?
Data erasure removes data through software-based overwriting, allowing the device to be reused afterward. Data destruction physically eliminates the device — through shredding, degaussing, or disintegration — making it permanently unusable. DES offers both, and we help you determine which method is appropriate based on your compliance requirements and asset lifecycle goals.
Is data erasure compliant with HIPAA?
Yes, when performed correctly. HIPAA requires that electronic protected health information (ePHI) be rendered unreadable and unrecoverable prior to disposal. Certified data erasure performed in accordance with NIST 800-88 Purge guidelines satisfies this requirement for most media types. DES provides the documentation needed to demonstrate compliance.
What is NIST 800-88 and why does it matter?
NIST Special Publication 800-88 is the federal government’s authoritative guide to media sanitization. It defines specific methods for securely clearing, purging, or destroying different types of storage media. Following NIST 800-88 ensures data is permanently removed in a way that can withstand regulatory scrutiny and third-party audits.
Can SSDs be securely erased?
Yes, though SSDs present unique challenges compared to traditional hard drives due to their architecture. DES evaluates each SSD and applies the appropriate NIST 800-88-aligned method — which may be overwriting, cryptographic erase, or physical destruction depending on the drive type and condition.
Do you provide a certificate of data destruction?
Yes. Every completed project includes a certificate of data destruction, along with serialized erasure verification reports, chain of custody documentation, and intake logs. These records are designed to satisfy internal governance requirements and third-party audits.
Can you handle large-volume tape erasure projects?
Yes. DES is equipped to handle high-volume LTO and enterprise tape projects with full asset tracking and documentation. If you are planning a tape library decommission or data center retirement, contact us to discuss logistics and project timelines.
What happens to devices that fail erasure verification?
Devices that fail verification are flagged, documented, and routed to certified physical destruction. This ensures that no device with potentially recoverable data is returned to service or passed downstream without proper sanitization.
Start Your Certified Data Erasure Project
Retiring storage media without a documented erasure process is a risk your organization should not take. Regulatory requirements, internal governance obligations, and the very real cost of a data breach all point to the same conclusion: certified data erasure is not optional.
DES Technologies makes the process straightforward, verifiable, and compliant — from the first asset log to the final certificate of destruction.
