Nah. You really can't have a hard link to a file on another filesystem. They don't allow it because it creates problems with keeping everything in sync. A symlink would work though.

JBOD would be a better idea if you really wanted it to appear as a single drive. Striping would cause both drives to spin up when reading a song which would definately be a bad thing. Still got the problem with one drive dying as you say for normal striping though.
