Hello there,
I had to replace my SDcard what I used as Adoptable Storage. I simply ejected it, assuming that all data on the SDCard is moved to internal but what happened only partial. Looks like that app data in Android/data was moved but anything in DCIM, Downloads, Documents etc is gone but luckily I made a backup in Recovery (TWRP 3.3.0). Next time I follow 6.0 marshmallow - My adoptable storage is full. How can I move the data to a bigger MicroSD card? - Android Enthusiasts Stack Exchange.
Once I inserted the new SDcard I migrated the data again. During this process, the progress bar jumped from 80 to 20 and to 80 per cent again several times and used storage on the SSCard was less than before but I didn’t care. Later I came across some strange things. WhatsApp wasn’t able to open/store images, screenshots failed to be saved (can’t save screenshot due to limited storage device) furthermore I was curious where e.g. the offline maps are stored as there isn’t that much space occupied on the SDCard
So I did some checks and figured out that the used storage figures in settings are non-sense, see below:
-
All storage
-
internal -> 14 GB other Apps and sum only nearly 23 GB
-
external -> sum is 5 GB instead of 4 GB and Apps is empty
-
DroidExplorer - recovery -> seems like that internal and external are matching expect pictures
- data\media\0\pictures\screenshots
- sdcard\pictures\screenshot same as \external_sd\media\0\pictures\screenshot
- data\media\0\pictures\screenshots
Furthermore, I noticed that why I boot into recovery, the SDCard isn’t recognised anymore in when booting back into System. I have to remove and reinsert for fully functional system&apps
By the way, what is the difference between choosing Internal Storage or External Storage in the mount menu of TWRP
