Hard Disk Monitoring

We are generating a SAS drive test process for a customer and their qualification criteria includes a lifetime temperature limit value.

We want to use the "Maximum Temperature (During Entire Lifespan)" in Hard Disk Sentinel but there is some question about how this value is obtained from the drive.

Our engineering consult could not access the lifetime max temp via the LOG SENSE command, and he subsequently monitored Hard Disk Sentinel commands to validate how this max temp value was obtained but could not make any determination.

Can you provide any detail on how the "Maximum Temperature (During Entire Lifespan)" is obtained that will give us confidence that the value reported by the Hard Disk Sentinel is indeed valid/accurate?

Thanks for your message and interest.

Yes, Hard Disk Sentinel has different methods/techniques designed exactly to detect and report the "Maximum Temperature (During Entire Lifespan)" value (if it is possible: if the disk drive records that value).

I'm afraid due to legal issues I can't really provide technical details about how this value determined: in many situations (especially with some SAS drives and/or depending on the SAS HBA or SAS RAID controller) special methods required. In order to use these methods, we have strict NDAs (Non-Disclosure Agreements) with manufacturers and they prevent releasing such/similar details or code source(s).
Generally this is why other solutions (eg. open-source) can be never as effective too in detection/reporting details.

As Hard Disk Sentinel detects and reports that value and has numerous ways to export the details (eg. by TXT, HTML, XML reports, by WMI and so) you can feel free to use the detected value as you prefer.
