(adsbygoogle = window.adsbygoogle || []).push({}); ok, so was playing CoD and all of a sudden an error poped, it said something that made no sence. so i turned off my Playstation, waited a couple seconds, then turned it back on. when i turned it on, this is what i got

"The Hard Disk needs to get rebuilt"

"OK"

so i hit OK, then this error poped up

"Rebuilding the Hard Disk will remove everything- gamesaves, downloads, etc....etc..

"Proceed?"
"YES" "NO"

i hit no and a blank screen came up. then i turned it off then back on and everything was gone.

what can i do to avoid this again???????
