Hi there,

 

Apologies for my ignorance.

Is it safe to assume that the attached smart report for a disabled drive is a dead drive that should be replaced?

Also, what part of it should I be looking at to tell that it is a bad drive?

Lastly, I probably bought this drive along with quite a few other of the exact brand and size (Seagate Barracuda 3TB) over the course of maybe 1 year around 3 or 4 years ago and this is the 2nd that I've had issues with. Am I ignorant to assume that they should last longer? I switched to buying 8TB WD Elements/MyBook for the last bunch of drives since they started coming down in price a few years ago. I also believe that they are higher quality WD White drives than the desktop based Barracudas.

Anyways, Thanks in advance for any help with the above questions!

That drive doesn't look good at all. If you click on it and look at its Attributes, you should see several lines that indicate monitored SMART attributes that are not good.

 

Attach diagnostics to your NEXT post in this thread so we can see if there is anything else of concern before you replace/rebuild the disk.

Thanks Truro!

I had no idea you responded until now. I used to get emails for responses and even marked this as follow. Attached is my diagnostics file. I greatly appreciate the help. tower-diagnostics-20221007-0648.zip

I wanted to pull the diagnostics file before updating to 11.1. Here's the one I just pulled after updating. tower-diagnostics-20221007-0725.zip

And here are the attributes for the failing drive. 

That is very dead indeed.

Thanks Kilrah. Wondering if the diagnostic files show anything else that may be going on that I can address prior to doing a rebuild. 

Do any of your other disks show SMART warnings on the Dashboard page?

Only the cache pool; however, it is only CRC Error Count issues which I have read could be due to bad sata cables. I ordered replacement ones in which will hopefully help. I am rebuilding the dead drive with a replacement now. I was wrong about the dead drive being a Seagate barracuda by the way. It’s a Seagate ironwolf which should be better quality than a barracuda.

Also, I ran a pre clear on the dead drive for fun and it just finished. Here’s the finished status preview:

In case that is hard to read, here’s a screenshot:

and here are the errors from the log:

preclear_disk_Z730W84C_25180.txt

 

looks like it’s a goner. After only 3 years.

That disk looks very sick and definitely needs replacing ASAP

Thanks, it had already been replaced but I figured I’d see what the preclear plug-in said about it. She gone.
