usb储存设备不能用？

apachluxun

usb控制器正常，如下：
0000:00:02.0 USB Controller: nVidia Corporation nForce2 USB Controller (rev a4)
0000:00:02.1 USB Controller: nVidia Corporation nForce2 USB Controller (rev a4)
0000:00:02.2 USB Controller: nVidia Corporation nForce2 USB Controller (rev a4)


模块已经载入，如下：
usb_storage            71232  0
scsi_mod               98788  2 sd_mod,usb_storage


挂载出错，如下：
# mount /dev/sda1 /mnt/usb/
mount: /dev/sda1 is not a block device (maybe try `-o loop'?)

我的usb是块设备啊，能看到多少块，如下：
Disk /dev/sda: 32 MB, 32768000 bytes
3 heads, 32 sectors/track, 666 cylinders
Units = cylinders of 96 * 512 = 49152 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1         667       31983+   4  FAT16[color="DarkOrange"] <32M
Partition 1 has different physical/logical endings:
     phys=(1000, 2, 32) logical=(666, 1, 31)

里边显示的[color="DarkOrange"] <32M我表记为红色的，啥意思啊？我挂了个2g的优盘也是这样，这个32m的也是这样？

我的是debian sarge 默认2.6.8挂载不了，刚编译的2.6.15-4也不行，knoppix就可以~~~

这是我的dmesg显示的信息，红色是我加的

我在xp底下格式化过了，也不行，fat格式的

哪位兄弟给我个思路吧，急死人了！！！

newroot

好像你的分区有问题吧，你把USB盘放到linux下重新分区然后再格式化一下！

但是 knoppix 用得好好的啊。而且我也重新分区过了，怎么用得不行……
