Are you looking for Ethernet checksum information or TCP crc info?  Unless you have a) a hub based network or b) Cabletron switches, you will not be able to capture Ethernet checksum issues.  All the switches that I worked with will not pass along damaged Ethernet frames.  Cabletron was the exception.
