i have the professional version and want to clone a mac hdd to a bigger drive on a windows pc. is this possible?

Currently the results may not satisfy you: HDClone can (and will) copy the drive without problem, but a) it doesn't recognize the GPT partitioning scheme (we have a somewhat working variant in our laboratories that is still far from release) and will therefore find no file systems, and b) it doesn't recognize the MacOS' HFS(+) file system and cannot expand it therefore. We are in the early stages of looking into this matter.

To my knowledge, booting for a Mac is much easier on the list of things to do, so initializing the disc under MacOS (this means writing the new partition table with the increased sizes) and then simply copying the files to it should already do the job.
