U盘挂载奇怪问题请教

forch

2.6.26内核，SAMSUNG2440
用fdisk命令查询有设备/dev/sda1 可是查看/dev下却只有sda没有sda1，不解，请教····

插入U盘，终端提示如下：
[root@forch /]# usb 1-1: new full speed USB device using s3c2410-ohci and addres

用fdisk命令查询
[root@forch /]# fdisk -l

Disk /dev/sda: 128 MB, 128450560 bytes

[root@forch /]#

查看设备没有sda1:
[root@forch /]# ls /dev/ | grep sda
sda
[root@forch /]#

在系统里查确有sda1
[root@forch /]# find / -name sda1
/sys/block/sda/sda1
[root@forch /]#

forch

把内核清理重新配置。文件系统里把sda1定位到udisk了。
[root@forch /]# mount /dev/udisk /mnt/yaffs/
[root@forch /]# ls /mnt/yaffs/
13579        xc7200~1     xcpost~1.gz
[root@forch /]#搞定

学习。

惟吾无为

会不会是你的udev规则把sda1重定向了? 而非链接.
