Unmount is just like as removing the
pendrive from the computer.We click on
remove USB before removing the USB. Unmounting is also like that but here we are
removing the memmory card from the smartphone. It is compulsory to Unmount SD
card before removing it, because at present it doesnot create any problem but
there are somany applications working behind the screen , these applications
need datas from the SD card if we suddenly remove the card it may cause
corruption to these applications.
So try to build a habbit of Unmounting SD
card..
