My macbook has been running a little slow lately, but when I went to power it up this morning it was stuck on the gray screen with scrolling wheel. Searched the boards, tried a safe boot and it shows me diskos2: I/O error over and over again but isn't booting. What next?

MacBook (13-inch Late 2009)

    Insert your original install dsc and start the computer while holding the C key down. Select your language and at the next screen from the Utilities menu select Disk Utility. Select your hard drive and first check the S.M.A.R.T status. Then select the repair option. It's possible that your hard drive has failed, hopefully you have a back up or you might lose everything. Let's hope for the best.
