Abstract: Embodiments of the present invention disclose a method and a device for detecting data reliability, which belong to the field of computer technologies. The method includes: dividing source data into multiple source data blocks; establishing a corresponding duplicate data block for each source data block, where the duplicate data block and the source data block are stored in different physical memory blocks respectively; establishing a corresponding reliability maintenance data structure for the source data block; and registering the reliability maintenance data structure with a first reliability maintenance thread of a central processing unit, the source data block corresponding to the reliability maintenance data structure registered with the first reliability maintenance thread, comparing a reliability check value of the source data block with a reliability check value recorded in the reliability maintenance data structure, and replacing the source data block having the error with the duplicate data block.
