Thanks but first all the software for my camera's was on a Mac not a PC.
Second here's what the Mathematica documentation says:
Raw (.raw, .arw, .crw, .nef, .nrw, .dng, ...)
Import supports raw images stored in a file with any of the following extensions: .bay, .bmq, .cr2, .crw, .cs1, .dc2, .dcr, .dng, .erf, .fff, .hdr, .k25, .kdc, .mdc, .mos, .mrw, .nef, .orf, .pef, .pxn, .raf, .raw, .rdc, .sr2, .srf, .x3f, .arw, .3fr, .cine, .ia, .kc2, .mef, .nrw, .qtk, .rw2, .sti, .rwl.
So according to the documentation the Raw format and the Import command in Mathematica says that .kdc is supported.
When you say tell us are you working for Mathematica? If so is the documentation for Raw/Import wrong--in which case you should fix it--or has the capability been lost at some point during Mathematica revisions without that being noticed?
