deionmann Posted March 1, 2015 Share Posted March 1, 2015 In my three years of using unraid, this is my first potentially failed disk, so please bear with me. In the dash it shows my disk as faulty, the icon however is not red (gui change?) Did a long and short smart check and the long shows read errors. However I've read that dirty power and/or bad cables can cause this from time to time. So my question is this disk genuinely bad? or should I go about replacing sata & power cables to further diagnose. Fyi: I already have a new drive ordered and an rma in with wd Linux 3.18.5-unRAID. root@Godzilla:~# smartctl -a /dev/sde smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.18.5-unRAID] (local build) Copyright © 2002-13, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Model Family: Western Digital Red (AF) Device Model: WDC WD30EFRX-68EUZN0 Serial Number: WD-WMC4N2781115 LU WWN Device Id: 5 0014ee 003d617ff Firmware Version: 80.00A80 User Capacity: 3,000,592,982,016 bytes [3.00 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: Sun Mar 1 00:19:12 2015 CST SMART support is: Available - device has SMART capability.

deionmann Posted March 2, 2015 Author Share Posted March 2, 2015 Just dont want to throw the new drive in there and fail the rebuild.... Link to comment
dgaschk Posted March 2, 2015 Share Posted March 2, 2015 Run pre-clear on the new disk as a test and then replace the faulty disk. This same procedure could be used on the faulty disk and if it passes pre-clear and a long SMART test then it would be good to use. The disk looks ok and I'd bet that after a pre-clear it will pass a SMART read test. Link to comment

deionmann Posted March 9, 2015 Author Share Posted March 9, 2015 Got the disk, rep replaced and rebuilt. Thanks allot dgaschk for the feedback. Ended up just rma'ing the old drive since it was still under warranty. Weird thing though, it took three attempts to rebuild, got to 99% twice then unraid would restart and automatically restart the rebuild. This happened twice, the third time the rebuild was successful. I've since run a parity check and all seems well so far. Weird Link to comment

Unexpected unRAID restarts are always worrying as they can indicate an underlying hardware issue. The symptoms you describe would tend to suggest either heat related (check your fans, clear out dust) or possibly a RAM stick going borderline (check with memtest from the unRAID boot menu).

deionmann Posted March 9, 2015 Author Share Posted March 9, 2015 Ok good to know. When I installed the new disk, I cleaned the chassis and checked all fans. I'll run memtest and see if I Can find anything. Thanks Link to comment
