My wife's relatively new Dell Studio 1569 is showing 2 drive letters. C & D. It has one 500GB hard drive that apparently arrived with a partition. C: drive has an allocation of only 58.5 GB and D: drive is showing 397GB. The C: drive is listed as OS and the D drive is listed as Local Disk. The C: drive has everthing in it from the Dell Folders to the Windows folder. It also contains the Program and Users files. Meanwhile, the D drive sits idle and recieves no data, file or programs. The problem is the C: drive (being the smaller of the 2) is almost full (10 gigs remaining) and D: drive is freed up. What solution could benefit me? And how can I accomplish it. Thanks to all who offer their time and expertise on this forum.
