置顶：mount sda1不能加载USB硬盘

90503

不识别USB硬盘，fdisk -l 下不显示USB分区   


请问大师：
本人用FDISK -L 不显示USB硬盘分区，
用LSMOD均显示USB-STORAGE...
用MOUNT -T VFAT /DEV/SDA ...
试了SDA ，SDB SDA1 ...都不行
请教。。。

把你的fdisk -l信息挂出来。

内核设置对了吗？
u盘需要usb和scsi的支持。

使用LSMOD 等命令均可显示USB-STORAGE，及SCSI—MOD

比如，我挂了一个USB闪存，用fdisk -l看，有如下信息：
[root@user root]# fdisk -l

最上面显示的就是USB-STORAGE的信息：Disk /dev/scsi/host0/bus0/target0/lun0/disc: 131 MB, 131072000 bytes说明就是/dev/sda1，有131M。

对了，有一种情况可能有问题，就是你的USB硬盘是NTFS文件系统。
