Hey guys! Just wanted to run something by you. My parity check just failed, throwing an error on my parity drive. Gemini says my drive might be dying. It's not even a year old, so still under warranty. Still kinda sucks though.

Can you help me with the log? Cheers!

You are likely to get more informed feedback if you attach your system's diagnostics zip file to your next post in this thread.

It is always a good idea to do this to allow us to see the current state of your system and so we can see logs and configuration information.

Thx for the reply! I will fix this when I get home from work.

Since I'm stuck at work right now, here's the pasted log. Sorry if spam. If it breaks any rules, please delete.

Drive is not generating a valid SMART report, possibly a bad drive, but try swapping ables just to be sure.

Changed the cables and ports around. It got recognized for a bit, but then threw some more errors, after which it went offline completely. I will be RMA'ing this drive. Thanks for the input so far!
