Hi,

First off, excuse my ignorance. I'm kinda new to UnRAID and trying to figure this all out as I go.

I am having a parity error issue. My last few parity checks had 515 errors so they're not being corrected ("Write corrections to parity" checkbox is checked).

From googling, it looks like I have to do some sort of SMART check?

I've attached my diagnostics.

 

Thanks so much!

First a couple of observations:

 

-Onboard SATA ports where the SSDs are connected are set to IDE, change to AHCI in the bios.

-You have am optical drive connect to an onboard Intel PCH SAS/SATA port and it isn't happy about that, it would be best to use a regular SATA port.

 

As for the the sync errors, log shows one correcting parity check, please run another one and post new diags if more errors are found.

Thanks for the reply johnnie.black.

Yeah, I'm a bit ashamed of that setup.

I just built a new machine, swapped over everything and ran another parity check. 0 errors!

That said, I'm now getting another error on my SSDs: udma crc error count is 5. I got it yesterday too but it said 1 instead of 5 then.

I hear it could be because of SATA cables not sitting right? Not sure.

I have attached my new diagnostics file.

Thanks for your help!

Not sitting right or just a bad cable, first step it to replace the SATA cable.
