The course of the process

Thank You for meeting us at the CeBIT fairs

Hard drive discs are round shaped slabs of the diameter amounting to 3,5 inch (or 2,5 inch), made of aluminium or aluminium alloys. They are covered with a thin and polished ferromagnetic layer made of ferrite materials and secured with the application of the proper protective layer. A single hard drive may contain even up to 8 discs, which ought to be destroyed.

The technology of chemical removal of data from hard drives is connected to the disassembly of discs from hard drive casing, next the discs are cut (shredded) and finally introduced into the water solution of a processing substance.

In the process of destruction the ferromagnetic layer of hard drive discs, which is the data carrier, it is subject to complete dissolving and is transformed into the solution of water soluble salts. As the result of influence of the proper chemical substances hard drive discs are subject to irreversible destruction along with all of the data stored therein – only a small portion of solution is left behind.

The whole process takes place within Mobile Data Destruction Centre (MDDC), within the location determined by the Client.

In a similarly effective manner we also utilise optical discs (CD, DVD), hybrid discs and SSD, silicon memories (such as portable USB memories, Secure Digital or Compact Flash memories), streamer belts, video belts as well as others, in accordance to the needs and requests of the Client.

Phases of the process of destruction:

  1. The arrival of our Mobile Data Destruction Center at the Customer's premises

    Customers may request the service to be performed at any location of their choice, which is of particular importance when liquidating carriers containing confidential or top secret information. In this case, the Mobile Data Destruction Center can drive up, for example, to the registry, eliminating the need to transport the data outside the location. This, in turn, eliminates the costs of secure transports, staff delegations, minimizing the risk of unauthorized access to data.

  2. Handing over the hard drives to be destroyed, against a taking-over certificate, including the verification of their identification data. The Customer needs to take stock of the hard drives beforehand.

    Before the drives are destroyed, the identification data of the received hard drives is carefully checked. This verification will form the basis for the documentation confirming the irreversible destruction of the specific data carriers handed over in order to be destroyed.

  3. Preparing the data carriers for the liquidation process (disassembly of platters, sorting and recovery of recyclable material)

    MCUD - rozkręcanie nośnikówIn a hard drive, the data carrier is the ferromagnetic layer on hard drive platters, which must be disassembled from the hard drive and destroyed. The remaining components of the hard drive – its casing and circuitry – are also sorted and recycled.

  4. Preliminary mechanical shredding of hard drives (chipping) to DIN 32757 (4th security level)

    Chipping is the preliminary stage, substantially minimizing the duration of the carrier destruction process. Smaller chips take less time to dissolve. The cover of the shredder is transparent, so the carrier and the chips that it produces are always visible.

  5. Destruction and dissolution of the carriers in the LiquiDATA process in the first reaction tank

    The first dissolution process of the chipped carrier produces a solution that can be used for waste water coagulation in waste water treatment plants, i.e. to remove suspended matter that does not deposit easily, or to increase the pH of, or even to neutralize, acidic waste water. Aside from the solution, the reaction produces ferrites that need to be dissolved in the second reaction tank.

  6. Destruction and dissolution of the carriers in the LiquiDATA process in the second reaction tank

    The second reaction ultimately dissolves all ferrites and minimizes the amount of waste. This solution can be used to neutralize the alkali received by waste water treatment plants, or, depending on the current needs, can be treated just like any other waste water

  7. Transporting the waste water to a waste water treatment plant

    There is no need for additional, paid recycling or utilization of waste, all waste water is being transported to a waste water treatment plant, and pieces of casing and circuitry to the corresponding recipients.

  8. Drafting and submitting a taking-over certificate (on site) and other necessary documents (within 7-14 days), including a certificate needed to remove the hard drives from inventory,

and, as an option:

  •  Supplying a recording of the entire process (within 7-14 days).

To provide the service, we need space to park our vehicle (preferably without any pedestrian traffic), approximately 4 m x 10 m (3 m x 8 m as a minimum), a 220V / 16A power supply (preferably three-phase power) and water supply
