I placed a new 160 GB SATA 2.5" HDD in my PS3 and switched it on. The PS3 asked to format it and I agreed. It then asked to restart but I powered down instead and placed it in a USB case.
Unfortunately, my PS3 ignores it while my Mac asks to format it.
Do I need to have my PS3 install anything else?
What format does your drive have according to OS X's disc utility?
