uSD Cards

Gemini (WiFi Only) - Firmware 2018-05-09.08

I have placed an 16GB uSD card in the internal slot (behind the screen) - this was originally formatted as FAT32 - in the Gemini it can be formatted as two ways

"internal" - card is encrypted, the key is held in the Gemini and card will not work in other devices
"portable" - card is not encrypted and can be removed.  i.e. files on it are no secure were someone to open the case the card can be read

I want to use "internal" as I have no need to remove it and will use as extra storage - ideally I need it encrypted as have no idea what will be on it  I use this method in both my Samsung J5 phone and a S2 tablet, it works fine.

If I format the card as internal it shows in the storage manager but it's not available to the filesystem - i.e. not showing in either the generic Android file manger or Solid Explorer.

If I format as "portable" within the Gemini it is visible to the the file system but not encrypted .  Although writing to the card seem to take a lot longer than I am used to with my Samsung S2

Removing and checking the card on my Lunux laptop with gparted shows it;s just a normal FAT32 card.  Putting the card back into the S2 tablet and it works fine so I think the card is OK

Has anyone got a uCF card reliably working as "internal"

Internal Card Format does shows as storage

Internal Card Format - does not show to filesystem

Re Format card as Portable

and now it's visible to the filesystem

Same here, SanDisk 8gb card formatted for internal storage is not visible in File Manager.
