Question

command on android terminal emulator to unmount the sdcard on my htc wildfire s device?

I have no option in the storage option under settings.

Answer 1

Have you tried:

adb shell
umount /sdcard

With the first command you open a shell with the device, and with the second you unmount the sdcard.

Answer 2

before type this:

adb root

than

adb shell

for android < 6.x type fuser -km /data , maybe need few times, for killing all process related with /data and then you can unmount your 'data'

 umount /sdcard

Answer 3

It required super user Access

umount /sdcard

For message: device or resource is busy! Restart the device and close the file manager if open, it worked for me
