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
smartctl version 5.33 [i386-redhat-linux-gnu] Copyright (C) 2002-4 Bruce Allen

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
