Generating error checking data for error detection during modification of data in a memory sub-system

A method comprising:

• identifying first and second data, wherein the second data is based on a modification operation performed on the first data,
• identifying first error-checking data comprising a Cyclic Redundancy Check (CRC) value of the first data;
• generating incremental error-checking data based on a difference between the first data and the second data;
• generating updated first error-checking data based on a combination of the first error-checking data and the incremental error-checking data;
• and
• determining whether the second data contains an error by comparing the updated first error-checking data to second error-checking data generated from a CRC value of the second data.

A method comprising:

• receiving a request from a host system to retrieve a first data;
• retrieving a second data associated with the first data and a second error-checking data of the second data, the second data corresponding to a modification of the first data and the second error-checking data being based on a cyclic redundancy check (CRC) value of the second data;
• generating the first data from the second data by reversing the modification;
• generating incremental error-checking data based on a difference between the first data and the second data;
• generating updated second error-checking data that is based on a combination of the second error-checking data and the incremental error-checking data;
• determining, by a processing device, whether the first data contains an error by comparing the updated second error-checking data to first error-checking data that is a generated based on a CRC value of the first data;
• and
• in response to determining that the first data does not contain the error, providing the first data to the host system.
