after long searching I found solution for not openable my storage.
edit file /init.rc and change the line:
mount vfat /dev/block/mmcblk0p5 /storage
mount vfat /dev/block/mmcblk0p5 /storage iocharset=utf8big thank for xiho for this. For me it worked. And if you want to use your storage as sd card (music only work in my device yet gallery and camera not), do this.
you can replace my storage to sdcard by editing the last row of etc/vold.fstab with your root explorer
dev_mount sdcard /mnt/sdcard auto /devices/platform/s3c-sdhci.0/mmc_host/mmc1 #/mmc1:0001
dev_mount sdcard /mnt/sdcard auto /devices/platform/s3c-sdhci.1/mmc_host/mmc0 #/mmc0:0001
then reboot your phone,you will find the sdcard should have been your my storage
i copyed from andylau so big thank for him too.
