    ▪Linux命令之hdparm-测试硬盘速度      功能说明：显示与设定硬盘的参数。 语法：hdparm [-CfghiIqtTvyYZ][-a <快取分区>][-A <0或1>][-c ][-d <0或1>][-k <0或1>][-K <0或1>][-m <分区数>][-n <0或1>][-p ][-P <分区数>][.........

    ▪linux查看硬盘型号及硬盘序列号的方法举例      本文介绍的查看linux硬盘型号及序列号的知识，主要是讲述hdparm命令的用法。 显示硬盘的相关设置   hdparm -i /dev/hda [root@cnscn ~]# hdparm /dev/sda /dev/sda: IO_support = 0 (default 16-bit) readonly = 0 (off) r.........

    ▪linux远程复制与上传文件夹的例子      1，将本地文件夹/home/administrator/Desktop/old/driver/test/ 远程上传到 192.168.62.10 这台机器的/root/文件夹下，使用远程端的root用户作为登陆用户：   scp -r /home/administrator/Desktop/old/driver/test/ root@192.168..........

代码示例:

hdparm -t /dev/hda （IDE硬盘）
hdparm -t /dev/sda （SATA、SCSI、硬RAID卡阵列）
hdparm -t /dev/md0 （软RAID设备）

-a<快取分区> 设定读取文件时，预先存入块区的分区数，若不加上<快取分区>选项，则显示目前的设定。
-A<0或1> 启动或关闭读取文件时的快取功能。
-c 设定IDE32位I/O模式。
-C 检测IDE硬盘的电源管理模式。
-d<0或1> 设定磁盘的DMA模式。
-f 将内存缓冲区的数据写入硬盘，并清楚缓冲区。
-g 显示硬盘的磁轨，磁头，磁区等参数。
-h 显示帮助。
-i 显示硬盘的硬件规格信息，这些信息是在开机时由硬盘本身所提供。
-I 直接读取硬盘所提供的硬件规格信息。
-k<0或1> 重设硬盘时，保留-dmu参数的设定。
-K<0或1> 重设硬盘时，保留-APSWXZ参数的设定。
-m<磁区数> 设定硬盘多重分区存取的分区数。
-n<0或1> 忽略硬盘写入时所发生的错误。
-p 设定硬盘的PIO模式。
-P<磁区数> 设定硬盘内部快取的分区数。
-q 在执行后续的参数时，不在屏幕上显示任何信息。
-r<0或1> 设定硬盘的读写模式。
-S<时间> 设定硬盘进入省电模式前的等待时间。
-t 评估硬盘的读取效率。
-T 平谷硬盘快取的读取效率。
-u<0或1> 在硬盘存取时，允许其他中断要求同时执行。
-v 显示硬盘的相关设定。
-W<0或1> 设定硬盘的写入快取。
-X<传输模式> 设定硬盘的传输模式。
-y 使IDE硬盘进入省电模式。
-Y 使IDE硬盘进入睡眠模式。
-Z 关闭某些Seagate硬盘的自动省电功能。
