Abstract
A system, method, and program product is provided that recovers from a sector error affecting a critical file. A damaged sector prevents a critical file from being read prevents the computer system from booting. A controller records a sector number corresponding to the damaged sector. The system is rebooted using an alternative boot media. The system accesses the primary nonvolatile storage media after the rebooting. The damaged sector number is read from the error log and a file map is used to determine the critical file that is stored in the damaged sector. A backup copy of the critical file is retrieved from a backup media. The backup copy is written to the primary media using undamaged sectors and the critical file is mapped to the undamaged sectors. The system is subsequently booted successfully from the primary nonvolatile storage media.
