I just bought a 4T HD and It has one partition and another part with unallocated space.. I can't create one partition for some reason.. I have tried partition manager and partition magic and no lock what can I do to turn this hd into just one partition??
 
Solution
To create a partition of larger than 2 TB the drive needs to use a GPT partition table. What version of Windows are you running? If this is to be used as a storage drive, look for the option "convert to GPT disk" then delete the current partition and create a new one.

Is the option to convert to GPT greyed out, when you right-click the 4TB drive in Disk Management?

I just rechecked the requirements and 64 bit is only required for a boot volume (a storage volume can work with either 32 or 64)

Perhaps you can try diskpart.exe from an administrator command prompt?
