What are the disadvantages of two dimensional parity check?

Two-dimensional parity checks can be limited in their ability to detect errors, as they may fail to identify certain types of errors, such as two bits being flipped in the same row and column, which can result in undetected corrupt data. Additionally, the method adds extra overhead in terms of storage and processing, as it requires additional bits for both row and column parity. This can lead to increased complexity in both implementation and error correction. Finally, it does not provide error correction capabilities, only error detection, necessitating a more robust method for actual data recovery.
