Just to add a bit to what Giuseppe rightly pointed out, a failure of all the inter-switch links that are in Are 0 between the two core switches will cause an isolated area scenario, not just a partitioned area.
A partitioned area is one in which a non-backbone intra-area link has failed and the area itself becomes split into two separate sub-areas. Assuming that each sub-area still has a connection to its ABR, the network may not be too adversely effected. One thing that will happen is that all the routes that would have been exchanged between those intra-area routers will go from being intra-area routes to inter-area routes because they will have to go through one of the ABRs to get to the other sub-area.
When the backbone area gets partitioned, this creates a scenario of isolated non-backbone areas. This is a much more serious situation; one in which one side of the network attached to one core router will be completely isolated from the other non-backbone areas that connect to the other core in Area 0. In short, they will not know of each other.s existence; they will not exchange routing information; and they will not be able to communicate between each other. You have effectively created two OSPF domains, each with one core router acting as Area 0.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
