No problems at all.  The Storage Group is just a list of directories.  
The file system takes care of available (and usable) storage space and 
Myth reacts to what the file system says at runtime.

Also, note that newegg is carrying the 2TB Seagates for $139.99 at 
http://www.newegg.com/Product/Product.aspx?Item=N82E16822148413 .  I'm 
not recommending Seagate or this particular drive or newegg or 
anything--just mentioning the price.
