Appendix. Compatibility notes

ECC testing

When an ST9816AG performs hardware-based ECC error correction on-the-fly, the drive does not report an ECC error. This allows ECC correction without degrading drive performance. Some older drive diag- nostic programs test ECC features by creating small data errors and then checking to see if they are reported. These tests, when run on an ST9816AG, may incorrectly report an ECC detection failure because the drive hardware corrects the data automatically, avoiding the error rather than reporting it. This type of report does not indicate a drive malfunction.
