I?m not even sure it?s the right term but here is the problem. I bought this used Dell 9100 that has two 500GB hard drives. The previous owner set it up as follows; System Reserved (C:) with 100MB total capacity & 48MB free space, Local Disc (D:) with 465GB total capacity & 453GB free space and Local Disc (E:) with 465GB total capacity & 399GB free space. The problem is I have some software that only works from drive C and there is no space there for it. I?m not sure what the previous owner intended by calling drive C a System Reserved drive as it only contains a few small folders and files. How can I find out which hard disk this C drive is part of and how do I join them back into one drive?
