What does 22 mean?

An error has been detected during the checksum verification of data stored in the EEPROM memory. This can affect various data sets, including firmware interface variables (S1, S2), system powerdown variables (S3), system parameters (S4, S10), or application-defined powerdown variables (S5, S6), suggesting potential data corruption within the drive's non-volatile memory.
