This read-only object reports the operational state of this CF card, distinguishing normal operation, sNoError, from various fault conditions such as format errors, sector buffer errors, ECC circuitry errors, controlling microprocessor errors, slave errors in True IDE mode, or I/O errors. Admins monitor it to catch a failing or corrupted CF card before it causes a boot or configuration-save failure, since these cards often hold the device's startup configuration and firmware images. An hh3cCfCardState reporting sECCError(4) would tell the admin that card's memory has a hardware-level integrity error and likely needs to be replaced.
