I need your help.
I read some posts but I didn't understand what's it.

My HD says there's a problem. I've attached diagnostics

Should be OK for now, and there's a recent successful extended SMART test, you can acknowledge the current errors and keep monitoring.

Do you know if there's a tutorial on the forum explaining the meaning of each thing?

[JorgeB]

Google SMART attributes, they are universal.

Hi, I continuous lost.

My server has a problem in Hard Disk, but I´dont know how to solve.

Its showing this error long time (4/6 months).
I've the impression that HD has a problem.

 

I already had problems with the first HD and now apparently with this one.
I'm thinking of stopping using Unraid because the HD spoils easily.

Could someone help me to verify if it is an error in the HD and how to solve these errors?
Thanks

PS: I always receive email alert about HD temperature....around 45 degrees

SMART is showing some issues, but they might be old, click the thumbs down and select acknowledge then see if new errors come up.

I get some errors every day, that's why i think have some problem.
But maybe this errors can be old.
Now I clicked the thumbs and showed "healthy OK"SMART REPORT ST4000VN008-2DR166_ZDH9T7NS-20230212-1323.txt

Can i test the HD? Where I must click?

I´m from Brazil. There are few people here who understand about Unraid.

Thanks for your help.

That disk has a lot of reallocated sectors which is never a good sign.   In theory if the number stays constant then you can continue using the drive, but if it keeps increasing then that is a definite sign that the drive could be about to completely fail.

FYI:  Reallocated sectors are nothing to do with the host OS - they happen completely internal to the drive and are invisible to the host OS.

I had a problem with an SSD last year.

And now with HD.

I never had hard disk problems before, but when using Unraid it happened.

Is it having excessive reading and writing on the disk or is it not resting?

Are you sure you never had any disk problems?   Most OS simply ignore these errors so you never know they are happening until the disk finally fails completely.  Unraid tries to give you some warning so that you can take pre-emptive action while there is still a chance to do something before data loss occurs.

Unraid is not making your disk reallocate sectors, just acknowledge the error and see if thy keep increasing, if they do replace the disk, if they don't you can keep it for now.

Yes I agree...I expressed myself wrong.

I've never lost data, disk never completely failed before.

In this moment, i received this.
Do you think I should put another HDD and replace it?

[itimpi]

Yes - the number of reallocated sectors is increasing so I would definitely say the drive should be replaced.

I'm going to replace the HD.

I only have one parity and one data drive.
 

I checked in the manual https://wiki.unraid.net/Replacing_a_Data_Drive that I need to remove the data disk from the array and put the other one and do a procedure in settings.

After that the data will already be copied to the new HD.

My question is.... how will the parity copy the data if the HD that contains the data will be disconnected from the array?

[JorgeB]

Data is restored from parity, with only a single data drive parity is basically a mirror.
