I have a Store Safe Pro 10 with an 80 gig hard drive in it. I would like to increase the hard drive to the max( 320, 500 gig) that it will handle. Is this something I can do myself and if so how or do I have to send it back to GE. I have build a couple of computers so I do have some knowledge but I'm not sure of how to program the new hard drive or install the wavereader program.
