Since Marshmallow (6.0) update on my Xperia M5 Dual SD card showing corrupted. but previously it was working fine on the lollipop.
after formatting the SD card in the safe mode, Phone detected the SD card.
but i cant copy paste anything into it.
when i use camera (data storage is set to SD card) pics are not saving on SD card, it is showing "There is some problem with your data storage"
I checked the SD card it is working in all other phones.
Any solution Please ..

I have noticed that Russia and Turkey has an even newer update for E5603 - 30.2.A.1.21; B for the dual....
MBoti , the new update is 30.2.A.1.21 ... no 30.2.A.0.110 !! Wait ....
It would appear that the problem has been resolved with 1.21....
Of course you don't need me to tell you that you can download it, and flash your phone with it via flashtool, right??????......
Cos seeing as I am from the UK, and we are usually the last to get this sh*t, how do you think I got it?....
It seems it was fixed in last update (30.2.B.1.21)
After update i cant access Engineer Mode
and still facing Shutdown issue.!!! 
Tried the update, it seems fine at first so i tried to restart my phone and then turn it off and then on again. To my surprise, the " corrupted SD card " message still appears, so i formatted my card, again. Transferred my files on the newly formatted SD card, restared the phone and it seems okay but when i checked for my files (MP3s, JPEGs) some of them are still corrupted. overall, seems like the updated didn't resolve the SD card issue.
