I previously consolidated two smaller drives to a single 400 gb drive using the default parameters for mfsrestore of -s 127 -r 4. Now I am adding a 300 gb drive. I see that once again there is a default value of -r 4 for mfsadd in the Tivo upgrade guide.

Is there an advantage to using a larger number for -r for adding the 300 gb drive? Is there an advantage, and is there a way, to increase the -s and -r parameters for the existing 400 gb drive?

When I look at the documentation it appears that boosting those numbers to higher settings could be useful for a configuration with lots of space and very large drives.
