CRC (cyclic redundancy check) is a checksum stored with each sector of data on the disk; if what is read back isn't quite what was originally writtin, the CRC checksum will come up bad.
What can happen with worn-out diskette drives is head-positioning errors that result in tracks being written in not quite the right place. Of course. they may read-back fine on the drive on which they were created, but fail in a flaky fashion on other drives that are either within-spec or out-of-spec in some way different from the bad drive.
Worn heads can also cause weak writing or reading, with a more unifiormly bad result.
