Recover data from SD card which is present as internal in Android 6.0

[AC Question]

I'm having lenovo k3 note with marshmallow update.
It features to convert external memory card to internal & I did so. I used migrate option in settings-->storage. But it copied lot of data to device storage, hence it end up in low memory space & I can't use my mobile. So I formatted mobile. But now it asks me to format my memory card, which is having lot of important datas. Even this memory card is not recognizing in laptop. It only allows to format to portable or internal storage in my mobile.Please suggest me to recover my datas. Thanks in advance!!!

Internal storage is only readable in the phone, not in external devices. See if Backing up an Android Device helps you.
