A data storage system includes a plurality of data storage drives, and a system controller coupled to each data storage drive of the plurality of data storage drives. The system controller is configured to store internal drive management data for each data storage drive of the plurality of data storage drives.

External storage of internal drive management data

A method includes writing first data to a first track of a magnetic recording medium of a storage device. First parity sectors corresponding to the first data are written. The first parity sectors have a first size. Second parity sectors corresponding to the first data are written. The second parity sectors have a second size. Second data is written to a second track of the magnetic recording medium. The second track is adjacent to the first track. It is determined whether an unrecoverable data error has occurred on the second track. After writing to the second track and determining that no unrecoverable data error has occurred, the first and second parity sectors corresponding to the first data are released.
