Data Erasure in Hong Kong with Licensed Blancco Software

Data erasure overwrites the whole storage area of a drive so the data cannot be recovered, while the hardware stays usable. HKRT erases laptops, desktops, servers, phones and tablets in Hong Kong using licensed Blancco software. Each device gets a PDF report showing its serial number, the method and the result, for your audit file.

Deleting, formatting, erasing and destroying are not the same

• Deleting files or formatting removes the pointers to the data, not the data itself. Recovery tools can often read it back.
• Data erasure writes over every addressable area of the drive, or uses the drive’s own sanitise commands, and then checks the result. The drive can be used again.
• Physical destruction (shredding, or degaussing for magnetic media) makes the drive unusable. It is the right answer when the hardware has no further use or your policy requires it. See hard drive shredding.

When people search for “certified data erasure”, what they usually need is erasure that produces a verifiable report for each device, rather than someone’s word that a drive was wiped. That report is what this page is about.

When erasure makes more sense than shredding

Erasure is usually the better choice when the equipment still has a life ahead of it:

• Redeploying laptops and desktops to other staff or another office
• Returning leased equipment at the end of a lease, where the lessor expects working hardware
• Reselling or donating equipment, where value recovery depends on the device still working. See asset remarketing.
• Reducing e-waste, because a working device that is reused does not need to be recycled yet

Shredding is the better choice when a drive has failed, when it cannot complete an erasure, or when your policy says data-bearing media must be destroyed whatever its condition. Many projects use both: erase what will be reused, destroy what will not.

What a Blancco erasure report shows

The report is generated by the software at the end of each erasure, rather than typed up afterwards, and you receive it as a PDF for each device, in English. It typically records:

• The hardware: device type, manufacturer, model and serial number
• Each drive erased, with its own serial number and capacity
• The erasure standard or method used
• Start and finish time
• The result, including whether verification passed
• Any drive that could not be erased

A drive that fails erasure is never treated as clean. It is set aside and physically destroyed, and that is recorded too.

Choosing an erasure standard

Your information security policy may name a standard. A common reference is NIST SP 800-88, which describes “Clear” and “Purge” levels of sanitisation. Tell us what your policy requires, and we will select the matching method and show it on each report.

SSDs and NVMe drives behave differently from hard disks. Because they manage their own storage internally, simply overwriting them is not always enough. The software uses methods designed for flash media where the drive supports them. Where a drive does not support a suitable method, we recommend SSD destruction instead.

How a data erasure project runs

1. Brief. You send an asset list or a description of the equipment, the location, and what should happen to the hardware afterwards.
2. Plan. We agree the erasure standard, where the work happens (at your premises or at our facility), and the documents you need.
3. Inventory. Devices and drives are logged by serial number before any erasure starts.
4. Erasure and verification. Each device is erased with licensed Blancco software and the result is checked. Drives that fail go to physical destruction.
5. Reports. You receive a PDF erasure report for each device, together with a summary of what was erased and what was destroyed.
6. Next step for the hardware. Equipment returns to you, goes back to the lessor, or moves on to remarketing or recycling, as agreed.

What to check before you choose an erasure provider

Whoever you use, a few questions quickly show whether the erasure will stand up in an audit:

• Can you see a sample report? It should show serial numbers and a pass or fail result, not just a device count.
• What happens to drives that fail? They should be destroyed and recorded, never released.
• Which standard is used? It should match the one your policy names.
• Where does the work happen, and who has access to the equipment between collection and erasure?
• How are reports delivered and matched to your asset list?

What we erase

• Laptops and desktops, including Windows, Mac and Linux machines
• Hard drives, SSDs and NVMe drives, whether removed or still inside equipment
• Server and storage drives from data centre and server room projects
• Phones and tablets that will be reused, returned or resold

Phones and tablets are erased with licensed Blancco software as well, and each one gets its own report. If they will not be reused, mobile data destruction may be the better route.

At your premises or at our facility

Erasure can be carried out at your office or data centre, so equipment does not leave the building before it is clean. It can also be done at our facility after a sealed collection. On-site erasure suits companies whose policy keeps data-bearing equipment on the premises. It also suits jobs where machines go straight back into use in the same office. Where some drives must be destroyed rather than erased, the two can be combined in one visit. See on-site hard drive destruction.

Our wording on Blancco

HKRT uses licensed Blancco software and operates it ourselves. We are not Blancco and do not act on Blancco’s behalf. Blancco is a trademark of its owner.

HKRT holds ISO 9001, ISO 14001, ISO 27001 and ISO 45001. For hard drives that are being reused, our hard drive wiping service page covers the HDD-only case. To plan an erasure project, contact us with the device types, quantities and location.
