I have a 500GB Samsung 840 EVO that had 2 partitions on it, and I wanted to turn it into just one partition, so I deleted one volume, but when I tried to expand the other, it keeps telling me that there isn't enough space on the drive to do that, even though there is over 100GB of unallocated space. It won't let me turn the 100GB into a new partition either unless I delete the 350GB partition, but when I do that, it won't let me allocate the 350GB of unallocated space. Do you guys have any suggestions?
