Hey all, I'm getting these errors and no matter what I try, I cant seem to get on top of them. This disk was originally on a Broadcom / LSI SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] (rev 03) controller (getting same errors) so I moved it to the onboard SATA controller and seemingly still getting the errors. I have replaced the sata cable a few times with no luck. Its a brand new disk so technically should be good..

 

However I may have to many HDD's in this system for the current power supply and I do have molex connectors piggy backed a few times to get the right amount of power connectors I need but these errors happen when all other disks are spun down. So i figure it could be a power issue but not so much a lack of power, but maybe quality of power coming through the piggy back cables etc??

 

I have done a fair bit of reading on this and typically its power or sata cable issue. I'm leaning towards power as its a new disk and getting same errors on different controllers but thought i would ask here before i make my next move. The power supply is a 500W model and I think has a single 32A 12v rail from memory.

 

I have only ever seen these errors on this same disk. All the other disks connected to either the onboard controller or the LSI controller have never had an issue that i am aware of.

Diagnostics attached.

 

Look forward to hearing what others thoughts might be.

 

Cheers.

quality of power coming through the piggy back cables

Seems like a possibility.

Do you know the best way to fix this? I believe the power supply and single rail is big enough but how do you go about getting the connectors you need?

Its something I have wanted to "fix" for a while but its never really been an issue until now so Ive just left it.
