I'm a brand new user of Unraid - installed it yesterday. I started setting up a couple of things during the evening, then just left it overnight to finish doing the parity initialisation.

This morning I woke to find the disks were all rather hot (around 60C) and one of them seemed to have failed. I shut it all down, let things cool down and fired it up again to be met with messages about disk failure. All these disks are new - I unpacked them yesterday!

I've run SMART on the problem disk (report attached). I also grabbed all the logs yesterday evening - syslog attached.

Now there's no data on anything yet, so I'm not concerned about data loss at this point and can just reformat and carry on if required, but can I do this, or do I have a duff disk? (Not exactly cheap, so going back if so ...)

Any suggestions gratefully received.

Sorry, thought the syslog might be enough there

OK, this is a Terramaster 6-bay DAS - am I just on the wrong track entirely with Unraid at this point then do you think? I was under the impression it should be fine with a DAS, especially with USB 3.2, but maybe I've made the wrong choice in this instance? (Once I've got this DAS setup I do plan on reinitialising my NAS using Unraid or similar rather than the QNAP software, which I have grown to really dislike ...)

Some USB bridges work mostly OK with Linux (and other OSes), but most don't, hence the general recommendation, but there are some users using USB.

I guess maybe I'm one of the ones that can't make that work - my own fault then for not researching which DAS to get more thoroughly

Ah well, c'est la vie. Many thanks all for the help. I must say this is a very helpful community. I'll be back once I have this DAS setup another way and can get all data across from my NAS so I an "unraid" that
