Wow, I seem to be posting here quite a bit... I'm so bloody useless...

Anyway, this morning I was playing Oblivion for about an hour, maybe two. I turned it off to do a few other things on here, and around the house. I came back about two hours later, and wanted to play some music while I did some more other things.

However... I turned the console on, and waited a while, but didn't hear the sound it usually makes when turning it on. About 10 secs later, a message came up saying "the correct Hard Drive couldn't be found" or something like that.

So, I came back online to find that this seems to be quite common. BUT I couldn't find a solution on the few sites I could get on (this laptop blocks everything), so I can't get on the BIG NAME Console sites.

What I did find was that some people found that it eventually worked after a little wait, or by switching the console on and off, and/or by dusting the PS3 out. Do these methods work?

Also, if I was to take the Hard Drive out to dust around, how difficult would that be? Would that do any lasting damage to the console?

Any help would be great, and I was wondering if any of you guys had had the same problem at some point?

Thanks in advance!
