Symptom
Some M.2 SSDs support a security feature called Self-Encrypting Drive (SED) with AES 256-bit encryption. These SSDs can enter a “blocked” state from the factory, even if they are brand new and have never been used.
When in this blocked state, the NAS cannot read the full drive attributes correctly and may interpret the drive as abnormal or show a warning, even though the SSD is not physically damaged.
This is a design of the SSD manufacturer, not an issue with QNAP NAS.
Solution
Perform an SED Secure Erase on the SSD to clear the blocked status:
1. Go to Storage & Snapshots > Storage > Disks/VJBOD > Disks.
2. Select a SED disk.
3. Click Action, and then select SED Erase.
4. The SED Erase window opens.
5. Enter the disk's Physical Security ID (PSID).
Info
The PSID can usually be found on the disk label. If you cannot find the PSID, contact the disk manufacturer.
6.Click Apply.
Warning
This process will completely wipe the SSD. Only perform it if you are sure the SSD is new or all data has been backed up.

症状
一些 M.2 SSD 支持一种称为自加密驱动器 (SED) 的安全功能，使用 AES 256 位加密。这些 SSD 即使是全新的且从未使用过，也可能从出厂时就处于“阻止”状态。
当处于这种阻止状态时，NAS 无法正确读取完整的驱动器属性，可能会将驱动器解释为异常或显示警告，即使 SSD 没有物理损坏。
这是 SSD 制造商的设计，不是 QNAP NAS 的问题。
解决方案
对 SSD 执行 SED 安全擦除以清除阻止状态：
1. 前往存储与快照总管>存储>磁盘／VJBOD>磁盘。
2. 选择一个 SED 磁盘。
3. 点击操作，然后选择SED 擦除。
4.SED 擦除窗口打开。
5. 输入磁盘的物理安全 ID (PSID)。
信息
PSID 通常可以在磁盘标签上找到。如果找不到 PSID，请联系磁盘制造商。
6. 点击应用。
警告
此过程将完全擦除 SSD。只有在确定 SSD 是新的或所有数据已备份的情况下才执行此操作。
