I mean at first test, when i've noticed that the files are wrong, i've copied some originial and overwritten the wrongly decrypted files. Then i've compared them and were identical. But after a restart of cubieboard, re-mount, re-check the diff showed differences again, probably because first time the file is read from cache, and not from the disk. -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
