In turns out the partition I made is too small (~8GB). I don't know why but after 8 months, I started getting warnings about this. I am not sure what to do but here is what I am thinking. (Note: I am not a techie) Option1 - back-up PC data files on shared parallels folder. - erase everything on the PC side (leave parallels) - change the HD partition size - reinstall - if this is the best option, how do I change the HD partition size Option 2 - same as above but put all my PC stuff on an external harddrive. with 2 partitions (1 for PC and 1 for mac) Option 3 - please tell me if there is a better way to do this thanks ari
