im running parallels 6 on a macbook and i noticed over the past 2 weeks or so ive lost about 10 gigs of memory. I looked around to see where is was all going and for some reason, even though i only partitioned 20 gigs for my windows xp partition, it has increased in size to about 29 gigs. i have no idea why this is happening, i made sure to select plain disk (not expanding) when partitioning, and im only using about 11 of the 20 gigs, i have no idea where these 9 gigs are. If anyone could help me that would be great.
