January 2, 20233 yr Hello and happy new year! i had to restart my server after a power failure at my home (the UPS did not seem to do its job but that another subject). Then i realized i had to manually start the array which typically starts automatically. When i did, i noticed one of my 2 data disks was disabled and the read check was paused at 0.0%. it sill is ~24 hours later. i am not sure what to do. After reading a few thread here, i tried to start an Extented SMART test on the disabled disk but i does not seem to start... i attached the diagnostics files. Does a disabled disk mean i have to replace it or can it be repaired? Thanks for your guidance. David tower-diagnostics-20230102-1259.zip
January 2, 20233 yr Community Expert Simultaneous problems in 3 disks using 2 different controllers: Jan 1 18:41:02 Tower kernel: ata3: found unknown device (class 0) Jan 1 18:41:02 Tower kernel: ata3: SATA link down (SStatus 0 SControl 310) Jan 1 18:41:02 Tower kernel: ata2: found unknown device (class 0) Jan 1 18:41:02 Tower kernel: ata2: SATA link down (SStatus 0 SControl 300) Jan 1 18:41:02 Tower kernel: ata4: found unknown device (class 0) Jan 1 18:41:02 Tower kernel: ata4: softreset failed (device not ready) Jan 1 18:41:02 Tower kernel: ata4: reset failed, giving up This suggests some kind of PSU or cable problem, check as cables especially any power splitters, then post new diags after array start.
January 2, 20233 yr Author Thanks JorgeB. I rechecked all cables including PSU and drives (unplugged, cleaned with a soft brush, re-plugged). This time, none of the disks of the array were discovered at startup! See picture and diagnostics files. The PSU does make a significant buzzing sound and the server itself makes buzzing sounds that cycle repeatedly every 1-2 seconds. So i rebooted the server again. this second time it did not come online at all (web interface not available)... i think i will order a new PSU and check again.

January 4, 20233 yr Author So i plugged in the new PSU and the server started fine. no more buzzing sounds. Disk 2 is still disabled. The reads, writes and errors counts on the Main page now show 0 each which was not the case before. I attached a screenshot and the new logs. What would you recommend i do next? tower-diagnostics-20230104-1848.zip
January 5, 20233 yr Community Expert SMART for disk2 look good and since the emulated disk is mounting you can rebuild on top: https://wiki.unraid.net/Manual/Storage_Management#Rebuilding_a_drive_onto_itself
