Okay to explain this issue in detail I attempted to resize partition D and add the size to Partition C, (this HD was orginally 1.5TB) anyway after about 5 times of failed attempts i noticed somthing strange. the space that was taken from Partition D is like gone or not readable in the "Computer" explorer window but it wasnt transfered to partition C. its gone. Partition D in Disk Management shows up 100% correct but when going to properties the computer returns a differnt result. I took a print screen for details.
Thanks to anyone who can help me out <3.
and sorry for the slightly pixelated image if you guys/ladies need i can try and clean it up abit.
