在准备替换或加装硬盘时，如何得到硬盘信息？
可以用smartctl,hdparm等命令来查询。
在日志中显示硬盘有坏扇区
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
dmesg中也有错误信息
dmesg
- ide: failed opcode was: unknown
- hda: no DRQ after issuing WRITE
- ide0: reset: success
- hda: status timeout: status=0xd0 { Busy }
对硬盘做一下健康检查
smartctl -H /dev/hda

- SMART overall-health self-assessment test result: PASSED
检测通过，保险起见还是准备换硬盘。
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"
smartctl -a /dev/hda

hdparm也可以得到硬盘型号
hdparm -i /dev/hda

也可以通过主板型号来得知支持的硬盘
