插入移动硬盘或者优盘以后,对于不一样的USB设备,不一样的机器,移动硬盘(或优盘)在系统中的设备标识(/dev目录下的链接)都是不一样的。
有时候是在/sdb1下面,有时候是在/sdc1, 或者/sda5下,也可能是其他的路径标识。在尝试了"mount /dev/sdxn /mnt/udisk" 3次,5次都没有找到后,任何人都可能感觉到泄气。
其实在我们可以用fdisk -l (注意是小写的-L,list的意思) 命令查看系统的所有存储设备信息。fdisk是磁盘格式化工具,所以在磁盘,包括移动存储设备还没有mount的时候,就可以检测到这些设备。
下面是我的电脑插上优盘约30秒(接上优盘后,会有片刻的检测时间)后,运行fdisk -l的结果:
Disk /dev/sda: 512 MB, 512229376 bytes
9 heads, 8 sectors/track, 13895 cylinders
Units = cylinders of 72 * 512 = 36864 bytes
Device Boot Start End Blocks Id System
/dev/sda1 4 13896 500107+ 6 FAT16
Disk /dev/hda: 80.0 GB, 80023182848 bytes
255 heads, 63 sectors/track, 9728 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 1736 13944388+ 7 HPFS/NTFS
/dev/hda2 1737 9729 64203772+ f W95 Ext'd (LBA)
/dev/hda5 1737 2884 9221278+ b W95 FAT32
/dev/hda6 2885 3648 6136798+ 83 Linux
/dev/hda7 3649 8512 39070048+ 7 HPFS/NTFS
/dev/hda8 * 8513 9156 5172898+ 83 Linux
/dev/hda9 * 9157 9666 4096543+ 83 Linux
/dev/hda10 9667 9729 506016 82 Linux swap
这里可以看到/dev/sda1是有盘,可以mount /dev/sda1 /mnt/udisk加载u盘。
