May 18, 20242 yr So last night one of my hdd went missing from my array. I assume it's because it's faulted. I have tried to run a test via a hhd software on windows, which show it as healthy. But I have tried to switch cables and replace it - nothing workings. I have attached a test from unraid - could anyone explain if it's faulted before I buy a new one? Side question: does anyone have experience buying iron wolf 20tb refurbished on ebay? and is it okay? I was planning to get one to replays my parity hdd and then use the parity as an array disk instead - i have two parity disk. I know its a chance to replace both a faulted disk and a parity at the same time... hdd test unraid.txt
May 18, 20242 yr Community Expert Disk looks fine, but there are UDMA CRC errors, so most likely it dropped due to a bad SATA cable, if you didn't yet reboot since it dropped, post eh diagnostics.
May 18, 20242 yr Author this dianostics is with a new sata cable - It was running through a HBA before - where the other four disk works. So far I have replaced it with another disk and run preclear on it - it shows up fine during unassigned dev... I properly try and replace the sata cable once more later... Thanks for the info

May 18, 20242 yr Author It didnt work with the new cable either. The disk was shown as unassigned. Both the old and new cable woeka fine with other disk. Im running a precleae on the disk now and temporarily installed another one instead. So im going to wait for the preclear to see, if I try and assign it once more...

May 18, 20242 yr Author I did try and reassign it, but then unraid wanted to reformat it - like a new drive. Well, I hope you guys are right. I just add it again after the preclear and not worry about it.
May 31, 20242 yr Community Expert Disk is rebuilding and no errors so far, post new diags if it doesn't finish rebuilding or there are errors.
June 1, 20242 yr Author So it must got disconnected again. I have switch all the cables to my hard drives - I used some SFF-8087, which I got with my HBA. I had some otherwise (longer), which I bought just in case those other onces wasn't long enough. I'm a bit worried, it maybe would be my PSU, but as far as I can tell at Corsair RM750 750W shouldn't cause problems... I was planning maybe to update my PSU next for a Corsair RM1000x Shift 1000W due to 16 x sata ports. I also use a HBA: OEM LSI 9240-8i, but was thinking of changing it to a - LSI 9300-16i 16-Port 12Gb/s SAS/SATA HBA or - LSI 9207-8i 6Gbs SAS 2308 PCI-E 3.0 I see online some HBA could cause problems. But mine have worked perfectly till now - but I had also added 2 more smaller HDD to it to try out zsf... Here is the report diagnostics-20240601-1540.zip Edited June 1, 20242 yr by sabonim38
June 2, 20242 yr Community Expert Lots of these before the issue: Jun 1 15:09:49 MidnightMystery kernel: sd 9:0:1:0: Power-on or device reset occurred They usually mean a power/connection issue, if you have already replaced the minSAS cables, any power splitters in use?
June 3, 20242 yr Author Nope, no splitters for that sata cable. I have now tried to take out all the sata cable and power cable and attach them again. I have removed the hdd from the array at the moment, but plan to try and add again, when I have time. I'm waiting for a replacement disk - just in case. So I'm not planing to do anything before it's here.
