June 20, 20224 yr Hello! i've set up my unraid nas since 4 months and everything was running fine, but 3 days ago one of my hdd had a problem and now isn't showing up in the array (now is in the unassigned device). I'm trying an extended smart self test to better understard which was the problem and if is better to change the drive o try to reassign to the array. What do you suggest? i've tried looking at the smart log but i'm not an expert and i didn't understand too much... Any help is appreciated! thank you!

June 20, 20224 yr Community Expert Disk looks mostly OK, if you didn't reboot since it got disabled posting the full diagnostics might give some more clues.

June 20, 20224 yr Community Expert Disk dropped offline before, this is usually a power/connection problem, check/replace cables and if the emulated disk is mounting and contents look correct you can rebuild on top.

Where i can find a howto?
July 4, 20224 yr Author I've tried to rebuild on top but there are a lot of error and i can't use the disk. maybe there is some real issue with the disk?

July 4, 20224 yr Community Expert There's a failing NOW attribute (reallocated sector count), that would be reason enough to replace, but there are also other bad attributes: ID# ATTRIBUTE_NAME FLAGS VALUE WORST THRESH FAIL RAW_VALUE 5 Reallocated_Sector_Ct PO--CK 140 140 140 NOW 1785 196 Reallocated_Event_Count -O--CK 176 176 000 - 24 197 Current_Pending_Sector -O--CK 200 200 000 - 2 198 Offline_Uncorrectable ----CK 200 200 000 - 2 200 Multi_Zone_Error_Rate ---R-- 197 197 000 - 1318
