Abstract
Detecting data corruption includes receiving one or more blocks of data to be written to a storage device, selecting a portion of the data in the blocks (e.g., one or more bytes or data words), applying a rule to derive information characterizing the selected portion of data (e.g., calculating a checksum for the for the portions of data selected from the block to be written), and storing this information. After the data has been written to the storage device, the store information is used in deciding whether the data has been corrupted.
