Two drives failed at once

Hi

 

Does this mean two of my SAS drives failed at once? Could it be the SAS controller instead? Please let me know how to diagnose

So many drives with issues suggest a controller or power/connection problem, post the diagnostics.

Please see attached diagnostics

This is happening with multiple devices, and these "Power-on or device reset occurred" errors usually mean a power/connection problem.

Thanks for looking at that so quickly. My PSU is 650 W so that should be plenty to power the system:

 

Typical Operating, Random Read (W)10.72 x 20 = 214W

Other components = less than 435W

 

That said, I daisy chained a few extensions to power the SAS drives. Would that cause this problem?

 

The tower has not been touched since it was working for the last few weeks. It seems unlikely that a connector has come loose. Any tips welcome.

 

Thanks

It definitely can.

The connectors can definitely work loose.

 

in my experience a SATA connector from a cable on the power supply cannot be reliably split more than 2 ways.   A molex connector can normally be split 4 ways without issues.

Thanks. I just bought 5 of the below molex to sata power adapters.

Also bought 5 extra molex outputs for the RM650x PSU (ideally I run max 4 HDs from one PSU socket):

Let's hope that fices it

Carefully check those molex->SATA cables.   I much prefer ones that have the cable crimped across the top of the SATA connector - the ones going in vertically like the cable you show are more likely to have manufacturing defects that can short two wires in the cables together which can then damage drives.

Not only that, they're also a fire hazard. There's a saying that goes: "Molex to SATA, lose all your data!"

If possible, could you please send me link to a good molex to sata adapter? Thanks

You can get exactly the same problem with SATA -> SATA if the wires go in vertically rather than horizontally.

You could try searching Amazon for “SilverStone SST-PP07-BTSBR - 30cm Molex to 4x SATA Sleeved Extention Cable‘.

[unraid newbie 55]

Thanks - just bought the last 4 of them

Thanks for this thread. I just purchased a couple of my Molex to SATA adapters with the crimped type connectors on the SATA port. I was not using the Y spliters 1 Molex into 2 SATAs. But a single Molex to SATA adapter cable.

 

Is the same advice recommended for a SATA cable Y spitter - that is a single SATA port which is split into TWO SATA connectors?

 

Thanks kindly....
