Abstract
System and method are disclosed for managing storage space of a magnetic storage device. The system may read data from a sector of the storage space and determine whether the data are successfully read from the sector. If it is determined that the data are not successfully read from the sector, the system may retrieve an address of the sector. The system may further determine whether the sector is subject to media fatigue based on the address. If it is determined that the sector is subject to media fatigue, the system may reallocate the sector subject to media fatigue to a spare sector.
