[OpenIndiana-discuss] Seagate 3000GB Drive only shows 746GB

[Rainer Heilke]

Yeah, I always use the whole disk (c4t0d0). Interestingly enough, I have 
to use slice 0 (c4t0d0s0) partition if I want to use the slice 
specification to "get the whole disk"; slice 2 doesn't exist, as you can 
see from the partition info. And slice 0, the "whole disk", says it's 
only 746GB, same as c4t0d0.... I've been fighting this for a while and 
tried most everything. :-(
