How do I merge a 500gb Hard drive?

Posted at: 2014-06-09 
I it is an internal HDD by default but I have connected to my laptop via USB. It is split into two partitions, OS and DATA. I have tried merging them with EaseUs but to no avail. Any help is much appreciated
The best way, is to move all data to one partition. then expand that partition, Win7 in Diskmanagement can do it.
