How to adopt external MicroSD card on “Samsung Galaxy Tab A (8”-2019)?

Hi,

I tried to partition my 128 GB -Kingston- MicroSD card into 75% adopted/internal and 25% external. However, the adopted/internal part was missing, meanwhile the external one was shown!

Before processing, the initial state was as shown below:

The partitioning command, for ID = 179,64, was as follows:

sm partition disk:179,64 mixed 25

After reboot, I realized that the adopted/internal part (should be, "ideally", 96 GB) is missing, and that the external one is shown:

The whole process is shown through the Windows PowerShell below:

K:> adb devices

List of devices attached

R9WN91B9GYJ device

K:> adb shell

gto:/ $ sm list-disks

disk:179,64

gto:/ $ sm partition disk:179,64 mixed 25

gto:/ $ reboot

K:>

Afterwards, I executed the following command:

adb shell sm list-volumes all

and here is the output:

K:> adb devices

List of devices attached

R9WN91B9GYJ device

K:> adb shell

gto:/ $ sm list-disks disk: 179,64

gto:/ $ sm list-volumes all

private: 179,67 mounted d8ef1b16-ab2b-4010-a1b1-79b1cc6cff16

private mounted null

emulated;0 mounted null

public:179,65 mounted 3484-15EF

emulated:179,67;0 unmounted null

gto:/$ sm list-volume all

usage: sm list-disks [adoptable]

   sm list-volumes [public|private|emulated|stub|all]

   sm has-adoptable

   sm get-primary-storage-uuid
   sm set-force-adoptable [on|off|default]

   sm set-virtual-disk [true|false]

   sm partition DISK [public|private|mixed] [ratio]

   sm mount VOLUME

   sm unmount VOLUME

   sm format VOLUME

   sm benchmark VOLUME

   sm idle-maint [run|abort]

   sm fstrim

   sm forget [UUID|all]

   sm set-emulate-fbe [true|false]

   sm set-isolated-storage [on|off|default]

   sm start-checkpoint 

   sm supports-checkpoint

gto:/ $

• Where is the adopted/internal storage?

• Is there something wrong?

• Is there a way to FIX?

• Is there a way to UNDO partitioning using ADB commands?

Thanks
