My favourite safety/disk utility - SoftRaid does not work with Snow Leopard OsX - and the new release has been "in the works" since early 2009.

But there is hope - as their website has the following new announcement :

The SoftRAID 4.0 official release is near. We expect sometime in late January to mid February 2010. Upgrades from SoftRAID 3.x will cost $69. All customers who purchased after January 1, 2009, are eligible for a free upgrade to SoftRAID 4.0.
