Im currently sorting myself out for Snow Leopard. I have an external hard drive i want to back some stuff up on to. The external currently has 3 partitions, all partitioned as Mac OS Extended (Journaled). I want to keep Partition 1 the same with all its data. Partition 2 and 3 i want to merge into one larger partition, and i dont mind losing data on these two. Ive tried using disk utility, but in the section where id add/delete partitions, the plus/minus buttons are greyed out. This is the same when running of the OSX install disk as well. Any suggestions?
