October 2, 20178 yr Hi I logged into my unRaid server for the first time in a long time.....and I see disk 3 is not intalled. Dont know when this happened - a problem when the system is so stable. I stopped the array and added disk from drop down but got insecure if that was the way to proceed. Is it ? System log attached tower-syslog-20171002-2054.zip
October 2, 20178 yr Community Expert Post the diagnostics file. 'Tools' >>> 'Diagnostics' It has much more information in it (including the syslog) which will assist those trying to help you.
October 2, 20178 yr Community Expert This disk: Device Model: WDC WD20EARS-00S0XB0 Serial Number: WD-WMC1H0011599 Has these errors: 197 Current_Pending_Sector 0x0032 200 200 000 Old_age Always - 18 198 Offline_Uncorrectable 0x0030 200 200 000 Old_age Offline - 18 This would cause unRAID to to take the disk off line. If it were I, I would replace the disk with a new disk and allow unRAID to rebuilt Disk 3. If you want to see if the disk is salvageable at that point, you could run the preclear procedure (via the 'Preclear' plugin) to see if these errors can be cleared up. I would use a least three cycles with zero errors after the first cycle. (That would be when those sectors should be replaced with spare sectors and the Reallocated_Sector_Ct would increase by 18.)

October 2, 20178 yr Community Expert Might I also suggest that you setup Notifications ('Settings' >>> 'Notifications' ) to provide you with warnings when things go awry with your server. It can save a lot of grief...
October 2, 20178 yr Author Thanks Frank - I'll order a new disk now. And change the notification setting.
December 24, 20196 yr I am facing the similar issue on my unraid. Posting the diagnostics. tower-diagnostics-20191224-0714.zip
December 24, 20196 yr Community Expert There's a problem with what I assume was disk4, it's failing to identify, try replacing/swapping cables, if it still not detected it's likely a disk problem.

Tried with all the hardware adjustments, Doesnt seem to work. Could be the disc completely? Is it dead or dying ?
