2. We need to create a partition on your SD Card or your microSD card.
2.a. To create a partition in our microSD Card, we will be needing a free tool called MiniTool
2.b. After you have download the MiniTool Partition Wizard, install it in your computerand Run MiniTool.
2.c. If your microSD card is new then you can proceed with creating a partition. If not be sure to back up everything in your microSD card. Creating a partition will delete every data in your microSD card. Proceed with caution. The first time I did this, almost all of my apps and games where gone, but they were still physically installed.
2.d. Plug your microSD card to your computer. While in MiniTool, right click yourmicroSD card drive and format it. REMEMBER: Be sure it is the correct drive and do this after you have backup every data in your card. Select fat32 as file system, hit ok and hit the apply button found in the upper left corner of MiniTool (the one with the big blue check mark).
2.e. After you have formatted it, right click on the microSD drive again and select Move/Resize . In my case I created a 1.37GB partition size while the unallocated space is set to 500MB. The unallocated size will serve as the additional internal memory of your android smartphone. Hit ok after you have set the partition size.
2.f. You will see in the MiniTool window an unallocated size in your microSD card. In my case, its about 506MB. Right click and create a partition for it, it will be formatted at the same time. Choose EXT3 as its file system. Hit the Apply button again after. Again be sure to hit the big check “Apply” button otherwise the changes would not be implemented.
3. After partition, you will only see the FAT32 portion of the microSD in your Windows Computer. But in Minitool you will see that there is a FAT32 and EXT3 partition. Now your done with the partitioning.
4. After you have created the two partitions (fat 32 and ext3), remove it and plug your microSD to your Samsung Galaxy Y (or android smartphone)
5. You will also be needing another app called link2sd .
6. Install link2sd in your smartphone, run link2sd and it will ask you to mount script. Choose ext3 and hit OK.
7. After you have successfully done that, reboot your android smartphone.
8. Once your phone returns from reboot, Run link2sd, go to its settings and check everything to auto-link. That should do it!
