A disk drive system-on-chip (SOC) includes a read-channel module and a processor. The read-channel module reads data, includes a first error-correcting module for correcting errors in the data, corrects errors in a first portion of the data using the first error-correcting module, and is unable to correct errors in a second portion of the data using the first error-correcting module. The processor includes a processor core and processor memory, receives the second portion of the data in the processor memory, and corrects errors in the second portion of the data using a second error-correcting module that is different than the first error-correcting module.
