I have recently recieved my new PS3 and after playing a few games and what have you I decided to unplug my 300GB external HD from my mac mini and plug it into one of the usb ports on my ps3. I went on my ps3 and evrything was working perfectly and then later on in the day I decided to once again unplug my 300GB external HD and plug it back into my mac mini.
Now this is where I have a problem as when I plugged it in on my mac it said from what I can remember 'This disc is not readable by this computer'. It roughly said something like that sorry I cant remember better. Then there were 3 options, it said either eject, ignore, or initalize. So I tryed initalize which opens disk utility and I tryed mounting the HD from there but I could and now I just have no idea what to do. Oh by the way it had worked fine before when I plugged it back in to my mac but this time it has'nt.
Thanks in adavnce :)
