I am sharing an external MAC drive with a Windows 7 guest operating system. How do I reassign the drive letter I see in Windows 7 for this drive? It is getting drive letter X:\ assigned to it and one of my Windows applications (ICAP/4 Spice) cannot tolerate it. Spice Technical Support found the problem and indicated it as a bug needing to be fixed. They said the work-around was to rename the drive letter. This is a MAC drive being shared with Windows 7 and I do not know how to reassign the drive letter. I have a 17" MacBook Pro (last years model) running OS X 10.6.7. I have 8 G-Byte of RAM (4 G-Byte assigned to the guest OS) and a 500 G-Byte hard drive with tons of free space. I am running Parallels Build 6.0.11994.
