FAT: utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!

# mount -t vfat /dev/sda1 /mnt

FAT: utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!
解决办法：

make menuconfig

File Systems --->

DOS/FAT/NT Filesystems --->

(utf8) Default iocharset for FAT

改为

(cp936) Default iocharset for FAT

mount -t vfat /dev/sda1 /mnt/udisk

可成功使用u盘 mini2440开发板

在插入u盘时

sd 0:0:0:0: [sda] Assuming drive cache: write through

sda: sda1

sd 0:0:0:0: [sda] Attached SCSI removable disk

FAT: utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!

不知道是不是utf8 is not a recommended IO charset 这个问题！！

我查看了u盘的格式

[root@EmbedSky /]# fdisk -l /dev/sda

Disk /dev/sda: 4002 MB, 4002910208 bytes

32 heads, 63 sectors/track, 3878 cylinders

Units = cylinders of 2016 * 512 = 1032192 bytes

Device Boot Start End Blocks Id System

/dev/sda1 * 1 3878 3908992+ b Win95 FAT32

但我用命令 mount /dev/sda1 /mnt/udisk 或 mount -t vfat /dev/sda1 /mnt/udisk等都会出现下面的语句就不行！

FAT: Filesystem panic (dev sda1)

fat_get_cluster: invalid cluster chain (i_pos 0)

File system has been set read-only

ls: /mnt/udisk/128x64: Input/output error
