The file is a binary file from my system. And the file has been checked for integrity before being copied over to the ubifs file system.
Wpr_004.wfp originates from a vfat partition, and was moved along with 10 other files, and then when I try to move the file back out from ubifs the read error occurs.

The partition/filsystem is created inside my system.
ubimkvol /dev/ubi0 -N wpr_slave -s 250MiB
mount -t ubifs ubi0:wpr_slave /mnt/slave
( first done format -> ubiformat /dev/mtd5 -> modprobe ubi mtd=5 )

Here are the result after enabling these two options.
How do I do cleaning in ubifs?

Mounting results from the partition
