Hi, When I go to Disk Management when being in Windows 8 OS and select my drive C and try to remap it to a different letter, I get the following message "The parameter is incorrect". What am I doing wrong? I have dropbox installed on my Mac side which holds files that are shared with my colleagues that use Windows OS. We all use a specific software that requires us to have the same file path, in our case it is "C:\Dropbox". The reason why I need to remap C drive letter to a different one is that I need letter C to be assigned to this Mac Dropbox folder.
