I have a 40gb PS3 went to do the 2.35 firmware upgrade, downloaded then told me it couldn't find the right hard drive, need to restore drive, I said ok and it started to reformat the drive, got stuck at 94% for 5 hours, I removed the harddrive and reformated it on my pc, same problem when I put it back in, it won't even let me on the menu screen. When I boot up without the hard drive it says correct hard drive cannot be found. I have tried reformatting the drive numerous times(fat32), got it reformatting up to 97% now and still getting stuck also I still can't access the menu screen. Any ideas??
i had a similar problem with my 60gig hdd when i was trying to swap it for a 750gig, but I can't remember how i managed to fix it. Mine got stuck at 56%. I think i just tried again making sure that the ps3 was off when i put the drive in, and it formatted properly.
