Just had a disk in with a similar out put to the initial thread:

(P)SATA Reset
Not Interface Age!
INVALID Cert Disk Code - ROM Resident Revision Required: AFZ3A0
Command Inactive - No VALID Cert Code Detected

Came from a disk which had allegedly been involved in a computer with an electrical surge. I have a feeling the IT support company had tried to sort it out themselves and had been swapping parts about; this fault was easily rectified on 7200.10 series. I can't say if it was similar issue on a 7200.11/12 whether it would be so easily fixed?
