Abstract
A disk drive is disclosed comprising a disk, a buffer memory, and control circuitry operable to receive a write command from a host, wherein the write command comprises write data and a write data address. Write EDC data is generated in response to the write data and the write data address, wherein the write data and the write EDC data are stored in the buffer memory. The write data is read from the buffer memory, and write check data is generated in response to the write data and the write data address. The write EDC data is read from the buffer memory and compared to the write check data to detect a write error. If the write error is not detected, the write data is written to the disk without writing the write EDC data to the disk.
