93dcfe9610 Slice Protection, Issue #366 
- Dean Jenkins has motivated me to implement additional protection from using a slice that does not fit within the capacity of the physical disk being used.  You can still assign an unusable slice, but when you try to refer to it, you will immediately get a "no disk" error from the OS.
