hdparm -i /dev/hda

显示硬盘的相关设置

[root@cnscn ~]# hdparm /dev/sda

/dev/sda:

IO_support = 0 (default 16-bit)

readonly = 0 (off)

readahead = 256 (on)

geometry = 19929［柱面数］/255［磁头数］/63［扇区数］, sectors = 320173056［总扇区数］, start = 0［起始扇区数］

.显示硬盘的柱面、磁头、扇区数

[root@cnscn ~]# hdparm -g /dev/sda

/dev/sda:

geometry = 19929［柱面数］/255［磁头数］/63［扇区数］, sectors = 320173056［总扇区数］, start = 0［起始扇区数］

.评估硬盘的读取效率

[root@cnscn ~]# hdparm -t /dev/sda

/dev/sda:

Timing buffered disk reads: 166 MB in 3.03 seconds = 54.85 MB/sec

[root@cnscn ~]# hdparm -t /dev/sda

/dev/sda: www.zhishiwu.com

Timing buffered disk reads: 160 MB in 3.01 seconds = 53.11 MB/sec

[root@cnscn ~]# hdparm -t /dev/sda

/dev/sda:

Timing buffered disk reads: 166 MB in 3.00 seconds = 55.31 MB/sec

.评估硬盘快取的读取效率

[root@cnscn ~]# hdparm -T /dev/sda

/dev/sda:

Timing cached reads: 3784 MB in 2.00 seconds = 1894.60 MB/sec

[root@cnscn ~]# hdparm -T /dev/sda

/dev/sda:

Timing cached reads: 3816 MB in 2.00 seconds = 1909.06 MB/sec

[root@cnscn ~]# hdparm -T /dev/sda

/dev/sda:

Timing cached reads: 3728 MB in 2.00 seconds = 1866.29 MB/sec

.检测IDE硬盘的电源管理模式

[root@cnscn ~]# hdparm -C /dev/sda

/dev/sda:

drive state is: standby [省电模式]

.显示IDE硬盘的内定硬件规格

[root@cnscn ~]# hdparm -i /dev/sda

.直接检测硬盘的硬件规格

[root@cnscn ~]# hdparm -I /dev/sda

.检测并设置IDE硬盘的32位I/O模式

检测

[root@cnscn ~]# hdparm -c /dev/sda

/dev/sda:

IO_support = 0 (default 16-bit) ［默认16位I／O］

设置

[root@cnscn ~]# hdparm -c 1 /dev/sda

.检测并设置IDE硬盘的DMA模式

[root@cnscn ~]# hdparm -d /dev/sda

/dev/sda:

… www.zhishiwu.com

[root@cnscn ~]# hdparm -d 1 /dev/sda

.检测读取文件时，预先存入快取的扇区数

[root@cnscn ~]# hdparm -a /dev/sda

/dev/sda:

readahead = 256 (on)

.查询并设置硬盘多重扇区存取的扇区数，以增进硬盘的存取效率

[root@cnscn ~]# hdparm -m /dev/sda

[root@cnscn ~]# hdparm -m 参数值为整数值如8 /dev/sda

.将内顾虑缓冲的数据写入硬盘，并清除缓冲区的数据

[root@cnscn ~]# hdparm -f /dev/sda
