Hello,

So, today I was playing my PS3 as normal, and then turned it off through the XMB menu, as normal. It turned off normally, but when my sister went to play it, things got weird. It gave a message saying that "the hard disk has been corrupted and will be restored," then went through a lengthy restoring loading bar. After it completed, it restarted the system. But, instead of going back to normal, it did the entire process again. And again. And again. It seemed the system was stuck in an infinite loop of borken-ness, so I checked the Playstation.com section on support. For the problem I had (which it described to the letter), it recommended putting the PS3 in Safe Mode, and then re-building the database. So I put the PS3 in Safe Mode, and selected Re-build database, but when I choose it, it gives me an error message saying that the hard disk can not be accessed. So now I'm pretty confused, as the restoring message makes it sound like the system is corrupted, while the error message makes it sound like the hard disk just isn't there. Does anyone have any ideas as to how I can fix this? Its a PS3 slim, fully updated, about 3 years old, and kept elevated and away from the wall to avoid overheating.

Any help will be apprecited.

I didn't find the right solution from the Internet.
