How do I perform a complete data erasure?
什麼是安全處理硬碟和 SSD硬碟的最佳方法？
Best practices involve using data erasure software to securely overwrite data on hard drives and SSDs, including the hidden areas and remapped sectors. Erasure is done per government standards such as NIST, DOD, and many more.
Erasure software is used before the drives are transported to equipment for physical destruction to eliminate the possibility of data being intercepted during transport. Physical destruction on hard disk drives can be done with a degausser that uses a powerful magnetic field, which erases not only the data but removes the servo tracks, making the media unusable. The most permanent and final destruction solution involves the use of granulators, also known as shredders. These machines rip, tear, or smash a hard drive or SSD into pieces so small that data cannot be recovered from the media or memory chips.
最好的方法包括使用數據清除軟件，將硬碟驅動器和SSD中的數據安全覆寫，當中包括隱藏區域和再變換區域中的數據。清除操作應按照政府標準如NIST、DOD等進行。在將硬碟運送到裝置進行物理銷毀之前，應使用清除軟件, 避免運輸過程中數據被攔截的可能性。
消磁器使用強大磁場來刪除數據，並消除伺服磁道，使媒體無法使用，適用於物理銷毀硬碟。而顆粒機，亦稱為粉碎機，則提供最徹底和最終的銷毀解決方案。這些機器可以將硬碟驅動器或SSD撕裂、撕開或粉碎成小塊，令數據無法從媒體或儲存晶片中恢復。
