After splitting my HDD in 2 partitions, is it possible to format my OS X partition or will I have to format the entire disk to format.
 
yes its possible to format just the osx partiton to free space and not damage the windows partition. i going to do some research for the application i used on the windows side of things and i'll post it soon.

edit: here is the link to partition logic. http://partitionlogic.org.uk/
now for some reason disk utility has to format the entire disk so don't use it.
