一、SD卡
1、通過fdisk -l命令確認板子上的Linux系統是否識別SD卡
/ # fdisk -l?
Disk /dev/mmcblk0: 63.8 GB, 63864569856 bytes
255 heads, 63 sectors/track, 7764 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
? ? ? ? Device Boot ? ? ?Start ? ? ? ? End ? ? ?Blocks ?Id System
/dev/mmcblk0p1 ? * ? ? ? ? ? 1 ? ? ? ? ? 5 ? ? ? 40131 ? c Win95 FAT32 (LBA)
/dev/mmcblk0p2 ? ? ? ? ? ? ? 6 ? ? ? ?7764 ? ?62324167+ 83 Linux
2、查看分區中的塊分配信息
/ # cat /proc/partitions?
major minor ?#blocks ?name
?179 ? ? ? ?0 ? 62367744 mmcblk0
?179 ? ? ? ?1 ? ? ?40131 mmcblk0p1
?179 ? ? ? ?2 ? 62324167 mmcblk0p2
3、掛載SD卡
mount -t vfat ? /dev/mmcblk0p1 /mnt/mmcblk0p1
mount -t ext3 ?/dev/mmcblk0p2 /mnt/mmcblk0p2?
4、卸載SD卡
umount ?/mnt/mmcblk0p1
umount?/mnt/mmcblk0p2?
5、格式化SD卡
mkfs.vfat /dev/mmcblk0p1
6、擴展
下面列出SD/MMC 所有相關驅動：
文件系統和存儲設備相關模塊
nls_base
nls_cp437
fat
vfat
msdos
nls_iso8859-1
nls_ascii
SD/MMC 相關模塊
mmc_core
himci
mmc_block
二、U盤
1、插入U盤
~ # usb 1-1: new high-speed USB device number 2 using hiusb-ehci
scsi0 : usb-storage 1-1:1.0
usbdev11 -> /dev/usbdev1.2
usb 1-1: USB disconnect, device number 2
usb 2-1: new full-speed USB device number 2 using hiusb-ohci
usb 2-1: not running at top speed; connect to a high speed hub
scsi1 : usb-storage 2-1:1.0
usbdev21 -> /dev/usbdev2.2
scsi 1:0:0:0: Direct-Access ? ? Kingston DataTraveler 3.0 PMAP PQ: 0 ANSI: 6
sd 1:0:0:0: [sda] 30720000 512-byte logical blocks: (15.7 GB/14.6 GiB)
sd 1:0:0:0: [sda] Write Protect is off
sd 1:0:0:0: [sda] No Caching mode page present
sd 1:0:0:0: [sda] Assuming drive cache: write through
sd 1:0:0:0: [sda] No Caching mode page present
sd 1:0:0:0: [sda] Assuming drive cache: write through
?sda: sda4
sd 1:0:0:0: [sda] No Caching mode page present
sd 1:0:0:0: [sda] Assuming drive cache: write through
sd 1:0:0:0: [sda] Attached SCSI removable disk
udisk2110 -> /dev/sda
udisk2110p4 -> /dev/sda4
其中： sda1 表示 U 盤或移動硬盤上的第一個分區，當存在多個分區時，會出現 sda1、sda2、sda3 等字樣。
2、掛載
mount -t vfat /dev/sda /mnt/usb
3、卸載
umount /dev/sda
4、格式化
mkdosfs –F 32 /dev/sda
5、擴展
下面列出所有USB相關驅動：

scsi_mod
sd_mod
nls_ascii
nls_iso8859-1
鍵盤相關模塊
evdev
usbhid
鼠標相關模塊
mousedev
usbhid
evdev
USB2.0 模塊
