I have a Sony VAIO VGN-FE21M laptop which has a hard disk drive partitioned into two drives, C: (74.5 Gb) and D: (67.5 Gb). The C: drive is largely for system and program files, whereas the D: drive is for user storage. I have used nearly all of the capacity of my C: drive but very little of the D:drive. Can I reconfigure the disk drive partitioning to allocate more space to C: from D:? In other words can I manage my hard disk to change the partitions or volumes that they contain? If yes, please can you advise how I do this.
