本文介绍下，在linux中查看硬盘型号等信息的命令，比如smartctl、hdparm等，有需要的朋友，参考下吧。
在中查看硬盘信息，比如硬盘型号，可以用smartctl,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-redhat-linux-gnu] Copyright (C) 2002-4 Bruce Allen
Home page is
=== START OF READ SMART DATA SECTION ===
SMART overall-health self-assessment test result: PASSED
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
smartctl version 5.33 [i386-redhat-linux-gnu] Copyright (C) 2002-4 Bruce Allen
Home page is
=== START OF INFORMATION SECTION ===

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% }

BuffType=unknown, BuffSize=8192kB, MaxMultSect=16, MultSect=off
CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=268435455
IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}

DMA modes: mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 udma2
AdvancedPM=no WriteCache=enabled
Drive conforms to: device does not report version:
* signifies the current active mode
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:
dmidecode
