When PB&R 12 Free is started and a wizard is selected a dialog box comes up saying "I/O error on hard disk drive 0 has occurred. What would you like to do?" I can force the action by selecting "Ignore all errors" but I never encountered this error in the past. Running CHKDSK /f /r returns no bad sectors found. No other program is reporting an I/O error with the hard drive. Could this have something to do with dual booting Windows 7 and 8? I recently reconfigured the hard drive in question and I have had some problems getting Windows 8 to boot, but that appears to have been resolved.
