Brillis Wuce :
It probably only cloned the single partition, which means you (hopefully) just have to assign a letter to the other 500GB.
Start > Right click on My Computer < Manage < Disk Management < find the empty 500 GB space and right click on it < Assign drive letter and path
Thanks for the answer.
Is there a way so that it can combine with the 500GB partition so that it changes to the original 1TB?
If I have to make it a different drive, will I have trouble installing programs on the partition?
