具体操作：
1：用鼠标点一下vmware里，把焦点转移到vmware
2。插入u盘，系统会自动识别
3。建立挂载目录，一般#mkdir /mnt/udisk
这时候他会自动检测到，然后用 fdisk- l看一眼 ，，
[root@yyl-0377 root]# fdisk -l
Disk /dev/sda: 5368 MB, 5368709120 bytes
255 heads, 63 sectors/track, 652 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 574 4610623+ 83 Linux
/dev/sda2 575 652 626535 82 Linux swap
Disk /dev/sdb: 130 MB, 130416640 bytes
8 heads, 32 sectors/track, 995 cylinders
Units = cylinders of 256 * 512 = 131072 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 * 1 995 127344 b Win95 FAT32
4。挂载 # mount /dev/sdb1 /mnt/udisk
然后进入/mnt/udisk 就可以了。
然后可以进行读写 ，想卸掉时用
#umount -l /dev/sdb1
