使用移动硬盘的问题

我照着文档“2.5.3 使用优盘/移动硬盘”试验，连接了一个移动硬盘到板子上面，udisk文件夹下面是空的，超级终端显示如下信息：
[root@FriendlyARM /]# usb 1-1: new full speed USB device using s3c2410-ohci and

U盘是可以的，为什么移动硬盘不行？

系统只会尝试自动挂载移动硬盘的第一个分区(sda1), 而很不幸的是，你的移动硬盘的第一个分区不是一个合法的FAT32格式的。

谢谢 kasim，我回头把盘格式化了再试，出于好奇，我想问一下，如果把第一个分区格式化成ext3能不能识别？

还有mini2440为什么不能识别NTFS呢？毕竟大于4G的文件还是要用NTFS格式的。

其实只要是Linux 内核支持的文件系统格式都是可以挂载的，只是自动挂载的脚本可能不行。你可以自己手动挂载，比如
$mount -t ext3 /dev/sda1 /mnt/disk

内核目前支持的文件系统类型可以通过命令
$cat /proc/filesystems
来查看

非常感谢kasim，我看到内核定制一章在“DOS/FAT/NT FileSystem”里面有关于"NTFS file system support"，是否表示钩上这个选项就可以支持NTFS了？

mount fat32的分区成功：

[root@FriendlyARM /dev]# mount -t vfat /dev/sda2 /udisk

看起来应该是的

学习

今天重新编译了内核，增加了对ntfs的支持，的确可以mount上ntfs的分卷了。但是，还是有问题，就是第一个分卷无法加载，比如，我的移动硬盘有四个分卷：
F: G: H: I: 前面三个都是ntfs格式的，I:盘是fat32格式的。我在每个分区里面分别新建了一个txt文件，文件名就是"盘符.txt“。我发现，后面三个盘都可以mount，就是F:盘不认，以下是超级终端上拷下来的:

我换了其他的移动硬盘也有同样的问题，无法加载第一个分区。
