Does degaussing a hard drive make it non-functional?
爲機械硬碟消磁會使它失去功能嗎？
When degaussing a traditional hard drive, the magnetically coated platters that store data are completely erased. Degaussing involves subjecting a hard drive to a magnetic field, which essentially demagnetizes the platters. The drive is rendered completely inoperable because there are no longer tracks and sectors on the platter which are used to organize and locate data.
Degaussing provides permanent removal of data and is recommended as a step in the data sanitization of traditional hard drives, tape, and other magnetic media. After degaussing, devices can be physically destroyed using a special shredder—the process guards against the possibility of any potential for possible data recovery.
對傳統機械硬碟進行消磁時，儲存數據的磁性塗層盤片會被完全清除。消磁是將硬碟置於磁場中，令盤片消磁。因為盤片上不再有用於組織和定位數據的磁道和扇區，機械硬盤完全無法操作。
消磁可永久刪除數據，建議用作淨化傳統機械硬碟、磁帶和其他磁性媒介數據的一個步驟。 消磁後，可以使用特殊的粉碎機對裝置進行物理銷毀——這過程可以防止任何有機會恢復數據的可能性。
