How to switch out a SD card that is formatted as Internal Storage?

Stop wasting your time trying to access any data stored within a microSD card formatted as Internal. If you want anything that is residing on that card, it's not going to be usable nor accessible to you. Your options are to either leave the card in your tablet or to reformat it back to Portable. The formatting process is going to wipe the card clean, that's inevitable.So if the SD card is formatted as "internal storage" and I try to reformat it to portable storage, all app data will be wiped? Or will just everything on the tablet be wiped (both the SD card and the tablet's storage itself will be erased)? Or will it still retain some data? If so, which data will be left remaining after reformatting the SD card?
And you said not everything can be backed up, so basically if I attach an external hard drive using a OTG cable, would I not be able to back up everything on my device (including apps and their app data)? I would basically only be able to back up or transfer files to it?
Thanks
In its default condition, when you originally bought it, the card's media storage was formatted with some form of FAT file storage variant, either FAT32 or exFAT. The FAT protocols being an old, proprietary Microsoft file system, that being old are minimally capable to still be usable with today's technology but having a benefit in being supported by almost all current operating systems (i.e. Linux, Microsoft, Apple, Android, iOS, etc.). But when you format a microSD card to be Internal, that's a significant change to the card's storage media. It's a) changed from FAT to ext4 and b) gets encrypted. Once the card is changed to Internal, its file system matches the same file system, ext4, as what your tablet's internal storage media is formatted to be. The encryption ties the card to your tablet, the encryption key locking the two to only apply to each other. So at that point the card, now being Internal, is morphed into a being just another internal component of your tablet's existing hardware configuration. The change to a corresponding file system and the encryption make the card usable as just a 'virtually' added amount of storage media.
So yes you have the option to manually reformat the card back to Portable (making the file system a FAT variant again and removing the encryption), but that does result in a somewhat drastic measure to your tablet's installed Android operating system. By doing this you're removing the amount of file storage it was using previously. So expect some data loss, most likely in just having to reinstall some apps.
