yak*_*kom 6 linux ssd hard-drive smart samsung-ssd
三星便携式 SSD T7 似乎不能很好地与 Linux 工具配合使用。该驱动器已被操作系统识别，基本功能运行良好。
但是，hdparm不会报告有关驱动器的任何信息：
SG_IO: bad/missing sense data, sb[]: 70 00 05 00 00 00 00 0a 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
两者都不会smartctl：/dev/sda: Unknown USB bridge [0x04e8:0x4001 (0x100)]
只有当我按照建议指定设备类型时，它才会显示一些内容，但输出不完整，我看不到任何 SMART 值：
# smartctl -a -d scsi /dev/sda

实际上划掉了我的评论。
显然该驱动器内部有一个 NVMe 驱动器。ATA PASSTHROUGH目前在任何 SCSI 标准中都没有针对它们的等效命令。因此，无论 hdparm / smartctl 对 NVMe 驱动器的支持程度如何，当它位于 USB 外壳中时，您最多只能获得通用 SCSI 支持（即可以直接从 SCSI 命令转换/映射的 NVMe 命令）。
事实上，与 (S)ATA 驱动器的情况不同，NVMe 到 SCSI 的转换当前（或曾经）仅由 NVM Express 工作组（显然也称为 NVM Express Inc.）维护作为参考，而 SAT是由 INCITS T10 委员会维护的正确 SCSI 标准。

此问题已通过Pull request #102修复。对drivedb的更新，告诉smartctl使用-d sntasmedia; 如果您的drivedb是最新的，它现在将“正常工作”，如果是backrev，请手动添加参数-d sntasmedia。您可以使用该命令独立于 smartmontools 更新drivedb update-smart-drivedb。
输出示例：
# smartctl --version
