Why did my SoftRAID driver get modified?
There is a bug in some utility programs which causes them to modify the code inside other applications. The application we know which does this is MacKeeper but there may be other applications which have the same bug. When MacKeeper modifies code inside the SoftRAID application and you subsequently install the SoftRAID driver, the driver will not load and your SoftRAID volumes will not appear.
If your volumes are not showing up and you are running Mac OS X 10.10, you can find a fix here.
