常見問題
靜電放電 (ESD) 簡單來說就是放出已積蓄的靜電荷。 不可輕忽靜電放電，因為它是電腦或硬體零件遭到個人損壞的少數原因之一。 它的效果就好像您用腳摩擦地毯，再以腳碰金屬物一樣。 發生靜電放電時，使用者不一定會感受到觸電，而且只會在處理電腦內部或硬體時才會發生。
如何有助於防止靜電放電
預防靜電放電最好的方法，就是使用防靜電放電腕帶或接地墊或接地桌。 然而，由於許多使用者並沒辦法取得這些東西，我們另外附以下步驟，以有助於盡量減少靜電放電發生的機會。
- 站立 - 我們建議您在處理電腦時隨時保持站姿。坐在椅子上會積蓄更多靜電荷。
- 電線 - 確保電腦後所有東西已清空 (電源線、滑鼠、鍵盤等)。
- 衣服 - 確保身上不穿著能夠傳導大量電荷的衣物，如毛線衣。
- 裝飾物 - 取下所有珠寶、首飾，也可有助於減少靜電放電並預防其他問題。
- 天氣 - 電風暴會增加靜電放電的風險；除非絕對必要，否則避免在電風暴發生時操作電腦。 在非常乾燥的環境中，每當絕緣表面上有空氣流過 (風、空調、吹風機)，空氣本身就成為電荷積蓄之機制的一部份。 別因為高濕度就以為會沒事，並留意互聯接頭與其他電氣介面的腐蝕問題。

Secure Erase User Guide for Linux

SATA Secure Erase Procedure
Warning
Please make sure to have a full backup of any important data before you proceed!
Prerequisites
• You must have root privileges.
• You must have your SSD connected to the system as a secondary (non-OS) drive.
• You must have lsscsi and hdparm installed. You may need to install them with your distribution’s package manager.
• Your drive must not be in a security freeze.
• Your drive must not be password protected.
Instructions
1. Find the device name (/dev/sdX) of the drive you wish to erase:
# lsscsi
2. Make sure drive security is not frozen:
# hdparm -I /dev/sdX | grep frozen
If the output shows "frozen" (instead of "not frozen") then you cannot continue to the next step. You must try to remove the security freeze by trying one of the following methods:
Method 1: Put the system to sleep (suspend to RAM) and wake it up. On most distributions the command to suspend is:
# systemctl suspend
Now issue the hdparm command again. If it worked the output will show “not frozen” (instead of “frozen”).
Method 2: Hot plug the drive. This is done by physically unplugging the SATA power cable from the drive and plugging it back in while the system is powered on. You may need to enable hot plug in BIOS. Not all systems support hot plug.
Now issue the hdparm command again. If it worked the output will show “not frozen” (instead of “frozen”).
3. Set a user password on the drive. The password can be anything. Here we are setting the password to “p”:
# hdparm --security-set-pass p /dev/sdX
4. Issue the secure erase command to the drive using the same password:
# hdparm --security-erase p /dev/sdX
This command may take a few minutes to complete. The drive password is removed upon successful completion.
If the secure erase is interrupted or otherwise fails your drive may become security locked. In this case you can remove the security lock using the command below and then try the secure erase procedure again:
# hdparm --security-disable p /dev/sdX

NVMe Secure Erase Procedure
Warning
Please make sure to have a full backup of any important data before you proceed!
Prerequisites
• You must have root privileges.
• You must have your SSD connected to the system as a secondary (non-OS) drive.
• You must have nvme-cli installed. You may need to install it with your distribution’s package manager.
• Your drive must not be password protected.
Instructions
1. Find the device name (/dev/nvmeXn1) of the drive you wish to erase:
# nvme list
2. Issue the format command to the drive. Here we set the secure erase setting to 1 which indicates a user data erase:
# nvme format /dev/nvmeXn1 --ses=1
This command may take a few minutes to complete.
