我在五台不同的计算机上运行过 smartctl -a（主要是 CentOS 7 Linux 和 smartctl 6.2），我注意到 smartctl 输出有两种样式。为什么它会改变输出格式？一种样式包含一个属性表，该表在智能维基百科页面。另一个不太明确，我想我必须简单地使用未纠正错误总数专栏。但我希望我能得到像第一个一样直接和易于理解的东西。
机器如下；除非另有说明，否则均为 CentOS7/smartctl 6.2：
- 台式机，没有 RAID。
- 配有 P420i RAID 卡的 HP DL380p G8 服务器
- 配有 P840 RAID 卡的 HP DL180 G9 服务器
- 一台旧的 HP DL360 G5 服务器，配有 P400i 和“Compaq Smart Array 642” RAID 卡（CentOS 6，smartctl 5.43）
- 带有 LSI MegaRAID 3108 RAID 卡的 Supermicro SYS-1028UX-CR-LL1。
在前 3 台机器上，smartctl 包含非常好的 SMART 属性；以下是典型的输出：
# smartctl -a -d cciss,1 /dev/sda
smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.10.0-123.el7.x86_64] (local build)
