October 12, 20223 yr 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 .server-diagnostics-20221012-1031.zip
October 12, 20223 yr Community Expert Solution Should be OK for now, and there's a recent successful extended SMART test, you can acknowledge the current errors and keep monitoring.

February 11, 20233 yr Author 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 server-diagnostics-20230211-1610.zip
February 12, 20233 yr Community Expert 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.
February 12, 20233 yr Community Expert 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. 21 hours ago, Braulio said: I'm thinking of stopping using Unraid because the HD spoils easily. 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.

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?

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.

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?
February 12, 20233 yr Community Expert Yes - the number of reallocated sectors is increasing so I would definitely say the drive should be replaced.

February 21, 20233 yr Author On 2/12/2023 at 9:42 PM, Braulio said: great... I'll do that Thanks you all for your help 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?
February 22, 20233 yr Community Expert Data is restored from parity, with only a single data drive parity is basically a mirror.
