I popped out the HD from my laptop & put it in the PS3, I was able to get the screen that tells me to have 4.40 on a USB and press select & start then again holding them.
I put my PS3 HD back in then held select start, it went through the format process all the way to 100%, the system then reboots to the Blue Screen of Death.
I can get it to format the HD booting with my laptop HD and the blue screen only comes with the PS3 HD, it will also give me the "Cannot start the appropriate system storage was not found" error if I boot sans HD. I'm thinking SGK fried my HD so I'm going to see about buying a used laptop hd at a PC shop later today.
