Are there any drawbacks to setting all LTO-2 drives to type hcart in 
this sort of environment?  Assuming, of course, that all LTO-1 drives 
have been removed from the environment, and the intent is to continue to 
use the older media for backups as well as restores?  My understanding 
of the Media Manager stuff is that the hcart, hcart2, and hcart3 
designations are solely for differentiating between drives types, and 
don't have any real effect on how the media is used.
