Degaussing (demagnetization) is a process for the safe elimination of the information contained in the hard disks and various media, based on exposing the memories to a strong magnetic field in order to eliminate the data and make the memory unusable, thus preserving the information stored in it from possible recoveries.
Degausser is a device that degausses hard drives, magnetic tapes, etc.
Note! For the data to be effectively removed, the electromagnetic field emitted by the device should be much higher than the magnetic coercivity of the carrier.
The National Security Agency has identified degaussing process (demagnetization) as an effective way to remove data from magnetic media.
Despite the fact that degaussing is a sufficient method of removing data from storage media, many companies decide to use a two-step process for destroying information: degaussing + physical destruction of media.
ADVANTAGES OF DEMAGNETIZATION:
- GDPR requires a preventive approach with data management and degausser is a proactive solution.
- Permanently data removal.
- Data can’t be recovered.
- Applicable to all magnetic storage media.
- Recommended for the highest level of data security.
- Faster than software method.
- You invest only once in the device.
- NSA, AAP recommended.
- Possibility to remove data from faulty or crashed media.
- Safe for operator.
DISADVANTAGES OF DEMAGNETIZATION:
- Cannot remove data from flash storage media.
- Media devices can’t be reused.
