Answer 1

I've been developing software for many years, and this would very difficult depending on how you wanted to do it. It might be doable if you are willing to live by certain restrictions.

If you wrote out to unused sections of the hard drive, FAT/NTFS wouldn't know where they were, so they would be prone to being overwritten.

1. You could create your own partition with it's own file system. This would be extreamly difficult, but would be possible and could be fun. Because it's in its own partition, it wouldn't get overwritten and could be used by your conversion software.

2. You could create a single file. Within this file was your file system. This would be easier, but wouldn't truly be a file system. It would be more like a fake imitation. However this is an easier approach and could be a lot of fun.
