Error Correction For Storage Devices

A method for performing error recovery for data stored on a track of a storage device, the method comprising:

• receiving a request to read the data from the storage device;
• identifying a plurality of sectors of the track to be read in response to the request;
• reading (i) the data from the plurality of sectors of the track, and (ii) parity data;
• based on the data read from the plurality of sectors, determining whether any of the plurality of sectors corresponds to a failed sector;
• and
• recovering a portion of the data from the failed sector using (i) the parity data and (ii) portions of the data stored in remaining ones of the plurality of sectors.

A system for performing error recovery for data stored on a track of a storage device, the system comprising:

• decoder circuitry configured to, in response to a request to read the data from the storage device,
• identify a plurality of sectors of the track to be read in response to the request,
• read the data from the plurality of sectors of the track, and
• based on the data read from the plurality of sectors, determine whether any of the plurality of sectors corresponds to a failed sector;
• and
• recovery circuitry configured to recover a portion of the data from the failed sector using (i) parity data and (ii) portions of the data stored in remaining ones of the plurality of sectors.
