Abstract
An apparatus for sustaining data throughput and methods of operating the same result in a drive apparatus that reduces overhead associated with recovery from write faults. The drive apparatus for sustaining data throughput having a file allocation unit including a plurality of sectors for storing data comprises a write controller coupled to the file allocation unit configured to write data to the plurality of sectors, a write fault detector coupled to the write controller and the file allocation unit configured to detect a write fault, and a write fault controller coupled to the write controller, the write fault detector, and the file allocation unit responsive to a detected write fault to skip a defective sector and restart the write controller to continue writing data to the plurality of sectors.
