A word of warning, at least one windows driver for extN has been known
in the past to corrupt filesytems.  Since it's not open source, we can't
debug or fix it.  Maybe it's fixed now, but I don't know.

It's not really an ext3-specific question, but you'll need to unbusy the
/home mountpoint to unmount it to reformat it; booting into single-user mode
would allow you to do that.
