Examples of industries need Data Erasure services:
- Computer upgrades that require large amounts of discarded Old hard disks.
- Hard drives that store sensitive data.
- Hard drive failures, but want to delete data in the sensitive
- Industry – banks, hospitals, accountants, lawyers, etc.
Ordinary person usually discard a bad hard drive in the computer without carefully processing the private data in the hard drive, it may cause the data to be exposed.
When computers are upgraded and replaced. Companies and organizations often worry about how to handle the data stored in the old computer's hard disk. In order to avoid leaking the company's data.
To completely remove the data on the hard drive, the safest and most effective way to permanently delete all data on the hard drive is using a degaussing machine.
Hard disk degauss
Magnetic degaussing principle is the degaussing produce a strong magnetic field, so that the magnetic flux on the media all converted to zero, so as to achieve the effect of permanent data deletion. According to the international standard degaussing machine strength generally need than the storage media itself more than 1.5 times or above the coercivity of the coercive magnetism can effectively destroy the data permanently. Also the track on the hard disk is converted to zero, the hard disk's head due to a strong magnetic field is destroyed. The hard drive cannot continue to use.
However, the tape or disk will continue to be used after degaussing because it has no head.
