Recover data from corrupt internal storage

[AC Question]

I was using a sd card as internal storage. However, two days ago the storage became corrupted.
I tried to recover the data using data recovery tools. But the recovered files are are and in un-readable format (some 6 .gz and 5 mpg file which are not readable). I require some help to recover the data. Can somebody help?

There is no chance. The files are encrypted.
