Parity Errors for a Raid 1 Array

[DBabk]

I am noticing a 65535 errors for a Raid 1 array. This is a 2 ssd intel drive array.

Is there any way to tell which of the two drives are having problems? Or what could be the issue here?

DBabk, Thank you for posting in the Intel® Communities Support. In reference to your question, in order to confirm which is the drive that is showing problems, first, we need to take the drives out of the RAID configuration, to do that please set both drives to "Non-RAID Disk" and then run the diagnostics tool: https://downloadcenter.intel.com/download/28593/Intel-Solid-State-Drive-Toolbox Regards, Alberto R.
