PS3 Hard Drive Corrupted

Ok I will walk do a step by step on what happened.

I turned on the PS3 to play MLB the Show 08 and my screen did the normal turn on with the intro music thing and went to the game, only except it flashed white and my screen turned black no music or anything from the game. I repeated that about 2 or 3 more times.

So I went to see if it was only the game so I turned the system off and put in Enemy Territory Quake Wars in and the normal intro music from the PS3 was fine then it turned on the game and it was fine. So it seemed like it was only that game.

So I tried it two more times from MLB The Show 08 and it did the same thing the first time but the second time after the normal intro music from the PS3 I got a message saying the PS3 Hard Drive was corrupted and it needed to be restored so it restored, the PS3 restarted itself and the message popped up again so I did that and have done it about 3 more times after that.....so whats wrong with it, is it from my game or I have just recently downloaded the 2.41 or 2.42 (can't rememebr its the latest one) so did the download screw up my PS3?

Formatting doesn't help ? I'm hearing lots of bad stuff about the initial Seagate drives ...change it quickly to a Samsung or Western Digital one of 250 or 320 gigs . Not only is the procedure way easy, you get enourmous amounts of space !! zekere

Where can i get one of those and how much are they?
