"Like many of you, I have a Samsung Galaxy Precedent that is quickly filling up internal memory. I have successfully rooted my phone but now want to use Link2SD to move apps to my SD card. So I can free up some space. But the problem is that I have no idea about how to partition my SD card. Does anyone have step-by-step instructions on how to do this job?"

A partition is simply a logical division of mass storage or memory into isolated subdivisions. This is normally done to help reduce the burden of the internal storage on the device. When you use an Android phone which lacks internal memory, you may need to partition the SD memory card inside the device to save more space on the internal storage. You can do it with a reliable SD card partition tool. It allows you to create partitions on the SD card to funnel a rooted device's applications to the card. In this case, you can install and run your programs from the card. 

Windows can only recognize the first primary partition on a removable device (USB flash drive, pen drive, SD card). If there isn't any primary partition, the first logical partition will be recognized. The newly created partition will not have a drive letter, and it cannot be recognized by Windows Explorer. 
Disconnect the SD card from your computer and plug it into your android device. Then, your old Android phone can recognize the SD card.
