I had a new hard drive installed in my rig. My old harddrive was copied to the new one. Here's the question: My old drive had 2 partitions one designated as C: and the other D: as purchased from the manufacturer (HP) I decided that since the D: partition was no longer needed I used "Disk Manager" to delete this partition. Problem is now that in disk manager my C: drive shows that it has 171.82 GB and I have a block of 293.94 GB of unallocated disk space. How do I add this unallocated space back into my C: so I have full use of all on C: disk. Does qwhat I said make any sense I'm stepping into the unknown knowledge wise so be easy on me pleese.
