September 5, 20178 yr Hi all, I'm running UNRAID 6.2.1 on an HP Proliant microserver and I've had an absolutely horrific time of it lately. I've been using WD Green/Blue 4tb disks in the server to run Plex. The issues started when my parity disk failed then 2 days later my first data disk failed. When I say failed I mean that in the most insane sense. I went to bed one night and woke up to find it had errors that numbered in the hundreds of thousands. I tried rebooting the server and it now no longer sees either of the drives. I tried removing the disk and putting it in a cradle to plug it into my computer and it doesn't see it either. It would appear that the drive has completely killed itself and now all the data is irretrievable. I'm not best pleased by any of this as I went with UNRAID because it boasts about disk protection and ample warning etc but absolutely none of that happened. These drives failed with no warning whatsoever and now I'm stuck with colossal data loss with absolutely no time to ensure it was backed up. What did I do wrong to cause two drives that are less than a year old to kill themselves like this and what can I do to prevent it in the future? There's another data disk in there that must surely be ready to commit suicide in a few short months as well. Please bear in mind that my technical skill is limited so I got this thing up and running through trial and error as well as reading online tutorials so be patient with me and my lack of technical knowledge. Thanks
September 6, 20178 yr Author Update, I got the array to see the drive again but haven't bothered to mount it this time. It seems that this error report was sitting on here: smartctl 6.5 2016-05-07 r4318 [x86_64-linux-4.4.23-unRAID] (local build) Copyright (C) 2002-16, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Model Family: Western Digital Blue Device Model: WDC WD40EZRZ-00WN9B0 Serial Number: WD-WCC4E1NV3A86 LU WWN Device Id: 5 0014ee 26288f162 Firmware Version: 80.00A80 User Capacity: 4,000,787,030,016 bytes [4.00 TB] Sector Sizes: 512 bytes logical, 4096 bytes physical Rotation Rate: 5400 rpm Device is: In smartctl database [for details use: -P show] ATA Version is: ACS-2 (minor revision not indicated) SATA Version is: SATA 3.0, 6.0 Gb/s (current: 6.0 Gb/s) Local Time is: Wed Sep 6 11:11:12 2017 PDT SMART support is: Available - device has SMART capability.
