C    J    Data scrubbing is another method to reduce the likelihood of data corruption, as disk errors are caught and recovered from before multiple errors accumulate and overwhelm the number of parity bits. Undetected data corruption, also known as silent data corruption, results in the most dangerous errors as there is no indication that the data is incorrect. In addition, if a corruption is detected and the file system uses integrated RAID mechanisms that provide data redundancy, such file systems can also reconstruct corrupted data in a transparent way. Some CPU architectures employ various transparent checks to detect and mitigate data corruption in CPU caches, CPU buffers and instruction pipelines; an example is Intel Instruction Replay technology, which is available on Intel Itanium processors.[13].
