Abstract
Embodiments for discovering read failures in a data storage system. Data read from underlying media of the data storage system is validated by initializing a prefix of a buffer used to read the data with a first sequence of bytes of a predefined number. The first sequence of bytes is compared to a sequence of actual bytes of the data read into the buffer. When the first sequence of bytes returns an equal value to the sequence of the actual bytes of the data read, a second sequence of bytes of the predefined number is generated and compared to a subsequent data read to determine the validity.
