I've got a HFS formatted disk pluged into a windows 7 machine which is pretty much my file server and does a bunch of other things. I want to be able to send my time machine backups to the disk rather than having to plug the thing in every time. Is anyone doing something similar? I just get the error it cant create the sparsebundle.. follwed a few links. I've setup W7 to read/write to the disk so that shoudnt be the problem.
