Hi I am using this guide to get a new HD into my PS3: http://asia.cnet.com/digitalliving/tips/0,3800004921,62032875,00.htm It says that the HD I back my PS3 up to needs to be formatted to FAT32. I have an external HD that I use with my mac, its partitioned into 4 parts. I have one partition which I don't use which I want to back my PS3 onto. In Disk Utility I select that partition and I only get 4 option under the Erase tab, 4 different Mac OS Extended options. I need help lease, any would be much appreciated.
