data erasure

The software used by SDR-IT guarantees complete erasure of data while preserving data carrier.

Among similar solutions existing in the market, only Blancco software can boast the highest efficiency confirmed with numerous certificates and recommendations. In the data erasure process it is important to obtain full access to data carrier, including hidden/blocked areas such as host protected area (HPA), device configuration overlay (DCO) and “reserve” sectors. Missing access to protected parts of data carrier may prevent certain data from being wiped.

The Blancco solution not only offers complete erasure of data, but also reports on correct performance of each process step.

When making decision on software-based data erasure, you should consider:

compliance of the service provider’s software with generally binding legal and technical requirements, certificates, permits and concessions, if required, issued by state administration bodies and international organisations
reporting method – report should include series numbers of devices, show continuity and compliance of data erasure process performed and full information on the person and company performing the process.
automated operation - the software used for data erasure must ensure adequate task automation level to efficiently carry out the entire operation without additional measures to be provided by the Client.
universality – the service provider should use a single solution across all storage devices e.g. HDDs, SSds, Flash memories The software should be fast and comfortable to use.
wide support – the service provider should offer support of various hardware platforms
efficiency – the software and other resources used by the service providers should enable erasure of data large volumes in short time, to reduce the costs of storing obsolete devices

Erasing data from mobile devices


With ever growing number of mobile devices used in everyday work, the volume of data stored in their memory has also increased. Data removal after mobile equipment service life expires may become an issue. Blancco Mobile Device Eraser used by  SDR-IT enables not only permanent removal of data stored in mobile devices, but also diagnostics of mobile devices to increase efficiency, improve security and ensure compliance, with the possibility of re-using the device as additional advantage.
Blancco Mobile Device Eraser software enables:

  • Diagnostics – identifying and solving efficiency problems using 42 IOS and 47 Android diagnostic tests
  • Data erasure – 13 erasure standards to be chosen from, including Aperiodic, random algorithms, Crypto Erase and DoD 5520.22M
  • Reporting – ensuring tamper-proof reports

Advantages of using Blanco Mobile Eraser:

  • is supported by many operating systems - iOS, Android, Windows Phone and BlackBerry,
  • quickly removes data from over 80 mobile devices simultaneously,
  • automatically selects the fastest and the most efficient method of data erasure,
  • has reliable tests allowing for solving efficiency problems (discharged battery, card failure),
  • complies with state, federal and international data privacy regulations, including NIST 800-88 Clear & Purge, GPDR, DOD 5220.22,
  • saves processing time due to automatic tests,
  • ensures data analysis on processed devices,
  • enables checking IMEI and FMiP numbers and operator’s blocks,
  • creates certified audit path secured against unauthorised access.

Secure data erasure is the last step of each comprehensive data security policy.

Patented method of erasing data from SSDs (patent no 9286231)

Whether the data are stored on SSDs, or on traditional hard disks (HDD), each entity has to ensure data security, and if necessary, eraseall information once the carrier on which such data are stored becomes obsolete. Erasing data from SSDs is a real challenge.

SSDs have simpler structure than hard disks, because they do not have movable metal parts. Moreover, they are smaller, lighter and require less power than hard disks. However, erasing data from SSDs is more complicated. SSDs use complex data management schemes to distribute data in internal memory systems. They also contain a much larger reserve pool or “redundant” memory available only through SSD. Such techniques extend drive capacity and service life, but result in hiding certain data on SSD from the host.

SSDs use complex data management schemes and contain a large pool of free memory available only to the hardware.

Data erasure system and SSDs:
  • Erase and format orders: Such orders are not effective, because some data can remain in the hardware and can be retrieved.
  • Demagnetisation: SSDs use integrated circuits to store data, and such circuits are electrically programmed. Demagnetisation does not effect the data stored in the SSD memory.
  • Physical destruction: Destruction of SSD makes it unreadable for third parties, however, in case of unskilfull disk destruction, a part or entirety of such data may be retrieved by a specialised entity. Moreover, the destruction of hardware reduces the return on investment, as such hardware could otherwise be used, recycled or resold.
  • Firmware Data erasure techniques based on software such as Secure Erase ATA are not applicable to SSDs, as their manufacturers did not adopt the standard approach to data erasure.
  • Cryptographic deletion: modifies the key used for data encrypting and decrypting. Data still remain in the hardware. Inappropriate implementation of cryptographic system may expose data to attacks.
  • Traditional overwriting: SSDs use complex data management schemes to distribute data in their internal memory systems. Overwriting techniques earmarked for hard disks do not cause permanent data erasure from SSDs. SSDs require specialised data erasure methods to correctly erase all data saved by users.

Major functions and advantages of the methods patented by Blancco

1. Hardware detection - Ensures that all SSDs are securely erased regardless of make or model.

  • Firmware Level Erasure – uses internal orders of data deletion hardware
  • Supports all SSD security protocols
  • Prevents any compression or deduplication mechanism being applied by SSD controller
  • Ensures that all steps are performed and completed in proper order
  • Fills the whole logical capacity of the drive with a random data stream
  • Process uses truly random / uncompressible data, not merely a repeating bit pattern

2. Data erasure- the same approach to SSD and HDD drives

  • Enables access to key internal SSD security features which are necessary to ensuring total and immutable data erasure

3. Verification - the entire drive is checked for the presence of omitted data, if any

  • Detects any anomalies in erasure process
  • Eliminates false error information

4. Certification - reporting confirming secure erasure of data from SSDs

  • 100% secures reporting process through digitally signed certificates confirming completed successive phases of data erasure
