Abstract

A method and apparatus for handling end of data processing in a data storage device. The method includes receiving a plurality of user data bits at a write channel. The method further includes appending primary padding bits to user data bits if the plurality of user data bits is less than a multiple of an input block length of an encoder in the write channel and encoding the plurality of user data bits and any primary padding bits into a plurality of encoded data bytes. Additionally, the method includes appending an end of data marker to an end of the plurality of encoded data bytes, wherein the end of data marker has a length of no more than one byte, and writing the plurality of encoded data bytes and the end of data marker to the data store.
