I'm running Lion and also have bootcamp Win7 installed. I haven't booted win 7 for a several month but some days ago was urged to do it. After successful boot in Win 7 I got some weird MacDrive error but disregarded it and just reinstall MacDrive. While using Win 7 I was navigating across my file system and have found that all my Time Machine backups were at the right place. After several hours I booted back to Lion and found that my Time Machine backups cannot be recognizeable anymore and the latest Time Machine copy was created just a day ago. The free space amount, however, remained unchanged as there still several copies.
I don't care about those backup data, I don't want to restore them.
The question I want to get answer for is whether MacDrive can break my Time Machine backups and how should one prevent it?
