当驱动器不健康时 smartctl 会输出什么文本

我运行此命令来检查驱动器运行状况：

smartctl -H /dev/sda

输出：

smartctl 5.43 2012-06-30 r3573 [i686-linux-4.2.0-rc3+] (local build)

=== START OF READ SMART DATA SECTION ===
SMART overall-health self-assessment test result: PASSED

如果磁盘不健康，输出会是什么？我没有这样的磁盘，无法学习这个。

像这样（SSD 已经报告此情况 6 个多月了）：

# smartctl -H /dev/sdb
