Hello Friends!

 

One of my drives errored out today and, looking at the logs, it appears that it was around a power-retract event. Short SMART test passed and no SMART errors on the dashboard but some suspect things in the drive SMART logs (attached). Looking for advice on where to start - checking cables, change out PSU vs drive, or is there something I'm missing?

Looking back at the logs:

In the drive SMART logs (attached), here are the things that stand out to me:

Device Statistics (GP Log 0x04)
Page  Offset Size        Value Flags Description
0x03  =====  =               =  ===  == Rotating Media Statistics (rev 1) ==
0x03  0x028  4              10  ---  Read Recovery Attempts
0x03  0x030  4               1  ---  Number of Mechanical Start Failures

 

The only only drive that has a non-zero Number of Mechanical Start Failures (also 1) is of the exact same model (and have been in another server before, so not certain how new it is).

 

Thanks in advance!

checking cables

 

Check the power cables and remove any splitters

Doesn't look like a disk problem, at least not media related, could be a mechanical issue, but first try swapping cables (both power and SATA) with a different disk and see where the problem follows

Thank you two for the replies.
That was my inclination as well, just wanted to see if I was missing anything in the logs. 
Will do some re-wiring and rebuild with the same disk for now. 
Will update with any additional events.
 

As a follow-up, this one disk eventually completely failed and no longer is recognized on multiple devices, despite spinning up.

Removed splitters and re-did all the cabling.

May have been the power, may have been bad luck.

Thanks again.
