Not according to his post, he just can't boot the partition the data is still there and there is nothing wrong with the drive. I assumed he wants to slave the mac drive to his Windows bench computer and the Macdrive software will allow him to see the drive and file system in a Windows environment, then it is a matter of copy and paste the files from the mac drive to your destination backup folder in Windows.
