This can be completed in one of two ways. Either in our very unique and state of the art mobile Onsite Data erasure  vehicle which has the ability to handle large volumes of data erasure activity from within the secure mobile facility; or alternatively we’re able to take our mobile data erasure solution in to a customers data centre, office environment or remote satellite location site and undertake the work there.

GreensafeIT utilise Blancco data erasure software which is a CESG Infosec 5 approved erasure application and the most certified and respected data erasure software in the market place today. All personal or confidential data is wiped from your devices and a certificate is provided per drive for compliance.

Typically our customers can request three types of service:

  • Onsite Data erasure from within our secure mobile data erasure lab
  • Onsite Data erasure from within the customers office or data centre
  • Onsite Data erasure and then shredding services from within our secure mobile vehicle which can handle both services

Our engineers are able to process high volumes of units with the tools and experience gained over many years delivering onsite services. Each item has a certificate of data erasure produced giving the customer a complete end to end audit process.

Essentially the service:

  • Manages data security concerns by erasing sensitive or restricted data at site
  • Provides visual erasure or destruction providing accountability for yourselves
  • Ensures there is no risk of data breach in transit.
  • Time and money saved through efficient erasure process

The data erasure/data wiping is a method of software based overwriting that completely destroys all electronic data residing on a hard disk drive. Permanent data erasure goes beyond basic file deletion commands, which only removes direct pointers to the actual files and makes data recovery possible with common software tools. Unlike degaussing or physical destruction, which render the disk unusable, data erasure/data wiping removes all information while leaving the hard disk drive operable, preserving assets and the environment.

data erasure

Onsite Data erasure/data wiping is a method that supports high end server and Storage Area Network (SAN) environments with the hardware support for Serial ATA, Serial Attached SCSI (SAS), Fibre channel disks and remapped sectors. The application operates directly with sector sizes such as 520, 524 528 removing the need to reformat to 512 sector sizes.

The erasure service caters for all flavours of technology

Hard Disk Drives

Data erasure/data wiping meets all approved erasure standards currently in circulation and GreenSafeIT can provide all algorithms upon request.

The application contains low level drivers for all the hard disks that it can erase. BIOS calls are never used in any event. Disks can be either IDE or SCSI-disks connected to a supported adapter or motherboard. The basic disk-operations that are used in the erasure process are: Inquiry, SMART self-test (optional), read, write and flush buffers. The Inquiry command is used to fetch the parameters of the hard disk: number of blocks, block size, vendor, product name, serial and revision. These parameters are then used to implement the erasure properly as well as those which are used in asset management.

The SMART self-test is for detecting the state of the hard disk. SMART reporting can be used to determine faulty hard disks even before data loss or other symptoms appear. The read/write operations that are standard disk-operations. The application write operations are always synchronised so that possible write errors are identified and flagged. Flush-command is run when required by hardware so that hard disk RAM-cache are emptied and data written to the disk platter(s).


The data erasure/data wiping process can be written as follows:

  • Fetch hard disk parameters (Inquiry)
  • Test hard drive for errors (SMART self-test, optional)
  • Write hard disk sectors with specified patterns starting with sector number 0, counting write errors as they come up as bad sectors.
  • Flush buffers – check if there’s any errors in this process.
  • If multiple overwriting passes are specified, the steps 3 and 4 are repeated. You will notice that the number of bad sectors are multiplied by the amount of overwriting passes.


Flash Media

Digital Media Shredder supports 4 international sanitising algorithms for erasing flash-type media:

  • Army Regulation, AR380-19
  • U.S. Department of Defense, 5220.22-M
  • Navy Staff Office Publication, NAVSO P-5239-26 (2 overwriting rounds)
  • Navy Staff Office Publication, NAVSO P-5239-26 (4 overwriting rounds)
  • All algorithms are can be catered for, including HMG Infosec 5 standards

Supported Media Types

  • USB thumb drives
  • Secure digital card (SD) memories
  • CompactFlash cards
  • Microdrives
  • MP3 players with flash drives
  • Digital cameras
  • Other flash based storage media

Mobile Technology

The main purpose of the application is to securely erase internal flash memory and other storage units (external memory card, SIM card) from the attached (via USB) smartphones. An erasure report can be generated containing the result of the erasure process. The report can be printed or saved to a hard drive/external media.

The erasure process is performed at a high level. It does not delete operating system files, integrated operating system applications or firmware updates. It does, however, delete all user content related to those applications. The external memory is fully formatted and overwritten. The phone books, call and messaging information on SIM cards are deleted and overwritten.

This data erasure/data wiping method conforms against all approved standards currently available.

GreenSafeIT use a professional data erasure/data wiping application that has been recognised as the most accredited erasure application on the open market.
