➔ Storage. 

2.   Touch Format SD card and then touch Format SD card 

again on the warning screen. 

3.   Touch Delete all.

To require a numeric PIN or password to decrypt your tablet 
each time you power it on or encrypt the data on your SD 
card each time it is connected: 

1.  From a Home screen, touch 

➔ 

Settings ➔ 

General tab

 

➔ Security.
