在linux系统中查看硬盘信息，比如硬盘型号，可以用smartctl,hdparm等命令来查询。
1，在日志中显示硬盘有坏扇区
复制代码 代码示例:
tail /var/log/messages
Mar 1 09:42:55 c1g smartd[1848]: Device: /dev/hda, 2 Currently unreadable (pending) sectors
Mar 1 09:42:55 c1g smartd[1848]: Device: /dev/hda, 2 Offline uncorrectable sectors
2，dmesg中也有错误信息
复制代码 代码示例:
dmesg
ide: failed opcode was: unknown
hda: no DRQ after issuing WRITE
ide0: reset: success
hda: status timeout: status=0xd0 { Busy }
3，对硬盘做健康检查
复制代码 代码示例:
smartctl -H /dev/hda
smartctl version 5.33 [i386-

=== START OF READ SMART DATA SECTION ===
SMART overall-health self-assessment test result: PAS
sed检测通过，保险起见还是准备换硬盘。
4，查看下当前硬盘的型号,可以得到硬盘接口为SATAII，及尺寸大小3.5"
复制代码 代码示例:
smartctl -a /dev/hda

5，hdparm也可以得到硬盘型号
复制代码 代码示例:
hdparm -i /dev/hda
/dev/hda:
Model=ST3160815AS, FwRev=4.AAB, SerialNo=6RA7DWM4
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% }

6，当然，也可以通过主板型号来得知支持的硬盘，使用命令dmidecode。
复制代码 代码示例:
