What key steps are involved in recalculating the CRC checksum after deleting a log entry from an EVTX file?

After deletion, the CRC32 checksum must be recalculated for both the file header (first 120 bytes) and the event records within ElfChunk (from offset 512 to `FreeSpaceOffset`). Additionally, the ElfChunk header checksum is recomputed using a 504-byte buffer that skips the event records data area. The article provides C code for CRC32 calculation and specifies the exact byte ranges needed for each checksum update.
