Interpreting ADU HDD fail log?

[mastsrl]

Hello,
i have a SAS HDD failure that's been reported by ACU(HDD blinks fail light) and i generated a report about it, the problem with ACU reports is that they're filled with hexadecimal values and are very cryptic to discover just WHAT the problem is, here's an excerpt of values that are clearly wrong compared to healthy drives:



Drive status:

Last Failure Reason Write Protected (0x0f)


Device Flag Status
SMART Predictive Failure Supported Informational
SMART Predictive Failure Errors Are Recorded In The Factory MP Data For This Drive Warning
SMART Predictive Failure Is Enabled Informational
SMART Predictive Failure Errors Are Recorded In The Since Power MP Data For This Drive Warning
Device Attached To Internal Connector Informational
Configured Data Drive Informational



Later in the MNP since factory:


Read Errors Hard 0x000000de

Other Time Outs 0x0025

Media Failures 0x0002

Predictive Failure Errors 0x00000036



and MNP since reset:



Read Errors Hard 0x00000003

Media Failures 0x0002

Predictive Failure Errors 0x00000002


i can't find any HP document on a list of error codes and interpretations(the individual values i can understand them, but what are the thresholds, why isn't there a simple SMART value/threshold viewer like any normal HDD?), what does the predictive hardware failkures value means?, Also, how come it gives "Write protected", how does an HDD is Write protected?!?!?!?, better put, WHY has the disk put himself in that mode(or the controller)
