Multiple cache partitions

I am thinking of experimenting with multiple cache_dir tags. I wonder if
anyone else has done this and could answer a question I have about it?

Once I have two partitions up, running and populated, what will be the
effect of subsequently removing one of those partitions?

Will Squid keep what's in the partition that is left and carry on or will
it ditch everything and have to start from scratch again?

Anyone got a rule of thumb for the max cache_dir size so as to maximise

Many thanks,
