My cousin's PS3 was failing (freezing, slowdowns, etc) so he decided to "copy" his hard drive content over to his PC in order to format it right after, despite my efforts to convince him Windows can't read PS3s filesystem. Obviously he ignored everything I've said and connected the PS3 HDD to his PC initializing it on GPT. Initially I thought he initialized it on MBR so I decided to copy the first sector from another HDD formatted on his own PS3 to the old one. Not only it didn't work but the PS3 wouldn't even start, green light to sudden shutdown with no LED. Then I figured he could've initialized it on GPT. Tried to copy the first 32 sectors from the newly formatted HDD to the old one. Now all I get is a black screen. I can get to safe mode but none of the options work. They all get stuck in "Preparing..." I do have an eid_root_key backup. What else can I do? ps3.exe (PS3 HDD Reader) says "no hdd(s) found!" when I try to use it. Probably because it looks for the appropriate first sectors and it isn't finding it.
