Ubuntu系统下查看硬盘信息的方法，可以查看到硬盘的型号、序列号、接口类型，转速，缓存等，这里记录一下。 方法一：直接通过内核查看 $ cat /sys/block/sda/device/modelST31000524AS$ cat /sys/block/sda/device/vendor ATA 方法二：用过hdparm命令查看 $

Ubuntu系统下查看硬盘信息的方法，可以查看到硬盘的型号、序列号、接口类型，转速，缓存等，这里记录一下。

方法一：直接通过内核查看

$ cat /sys/block/sda/device/model

ST31000524AS

$ cat /sys/block/sda/device/vendor

ATA

方法二：用过hdparm命令查看

$ sudo hdparm -I /dev/sda

/dev/sda:

ATA device, with non-removable media

Model Number: ST31000524AS

Serial Number: 9VPF38YC

Firmware Revision: JC45

Transport: Serial, SATA Rev 3.0

Standards:

可以发现，通过这种方法，看到的信息很全面，连硬盘型号，序列号，容量，接口，转速全都看到了。

方法三：通过lsscsi工具查看

$ sudo aptitude install lsscsi

$ lsscsi --device

方法四：通过scsitools工具查看

$ sudo aptitude install scsitools

$ sudo scsiinfo -l

/dev/sda

$ sudo scsiinfo -c /dev/sda
