My 60 gig did the same thing. I wouldnt call Sony they will charge you $150. Your warranty is out so you won't hurt anything by trying to fix it yourself. I used this guy's guide and it worked perfect. Looks intimidating but it works.

If you have important stuff on your hard drive likes pictures, videos, etc; you're gonna need to do this fix cause you can't put your hard drive in another system and access your files, it's gonna want to format the drive. I did this fix and my system worked a couple months until a couple days of Uncharted 2 caused it to happen again. I did the fix again and got my system working again, but ultimately I bought a slim model cause they're only $300, far cry from the $600 I paid for my 60 gig. I would recommend doing the fix to access your hard drive; save your game saves, pictures, and videos to a thumb or external drive. Then just buy a slim model and store your old 60 gig as a large ps2. Ultimately though I believe once the ps2 is off the market Sony will have a firmware patch for all ps3 models to play ps2 games. Goodluck!!!!
