1，用fdisk -l 可以得到系统中已安装的硬盘列表及分区情况
[root@localhost lhd]# fdisk -l
Disk /dev/sda: 40.0 GB, 40060403712 bytes
255 heads, 63 sectors/track, 4870 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xf0b1ebb0
Device Boot Start End Blocks Id System
/dev/sda1 * 1 1275 10241406 c W95 FAT32 (LBA)
/dev/sda2 1276 4870 28876837+ f W95 Ext'd (LBA)
/dev/sda5 1276 2550 10241406 b W95 FAT32
/dev/sda6 2551 2575 200781 83 Linux
/dev/sda7 2576 4870 18434556 8e Linux LVM
2，如何得到硬盘的品牌及相关信息
1，smartctl -i /dev/sda
说明： smartctl是用来控制和监视 smart disk的程序
-i 参数用来显示设备的相关信息
例：
[root@localhost lhd]# smartctl -i /dev/sda
smartctl version 5.38 [i386-redhat-linux-gnu] Copyright (C) 2002-8 Bruce Allen

2，有时使用smartctl不能得到我们预期的信息，例如：
[root@dev ~]# smartctl -i /dev/sda
smartctl version 5.36 [i686-redhat-linux-gnu] Copyright (C) 2002-6 Bruce Allen
Home page is http://smartmontools.sourceforge.net/
Device: Dell VIRTUAL DISK Version: 1028
Device type: disk
Local Time is: Wed Jan 28 23:09:50 2009 CST
Device does not support SMART
这种情况如何处理:
[root@dev ~]# cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: SEAGATE Model: ST3146855SS Rev: S527
Type: Direct-Access ANSI SCSI revision: 05
Host: scsi0 Channel: 00 Id: 01 Lun: 00

Host: scsi0 Channel: 01 Id: 00 Lun: 00
Vendor: Dell Model: VIRTUAL DISK Rev: 1028

3,如何得到usb设备的信息
lsusb
例如：
[root@localhost lhd]# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 002: ID 046d:c00f Logitech, Inc. MouseMan Traveler/Mobile
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
查看详细信息，可以加 -v
lsusb -v
查看某一个设备：
[root@localhost lhd]# lsusb -s 003:002 -v
