batt01 Posted March 10, 2016 Share Posted March 10, 2016 I have attempted to preclear a 4tb Toshiba drive. twice. It has failed twice at the exact same stopt. The drive is brand new. Installed it as parity, without preclearing first. After a few hours of parity sync, I would find the disk with a Red X, disabled. It get no useful info in the putty/preclear screen. It just froze, text pasted below. Also the web ui is inaccessible after the preclear failure, reboot is required to restore. This is anew build with all brand new parts. Log attached device in question is Y5OAKE1QFSAA (sdb) 3907018584.

John_M Posted March 10, 2016 Share Posted March 10, 2016 You need to take a SMART report of the disk in question. If that doesn't reveal anything, try running the long self-test. Quote Link to comment

trurl Posted March 10, 2016 Share Posted March 10, 2016 All the drives appearing in your diagnostics appear to be drives you have already assigned so the drive you are talking about seems to be missing. Can you access its SMART attributes and post them? Quote Link to comment
John_M Posted March 10, 2016 Share Posted March 10, 2016 I see that sdb has only negotiated a 1.5 Gb/s link with its controller, ata3, while other disks have full 6 Gb/s SATA links. Perhaps you have a cable problem? Mar 9 18:36:32 Loopcerv kernel: ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 310) Quote Link to comment

I have 3 cables and all bays are connected. Only tow cables are in use. So I think good test would be to pull the cable attached to Sdb and swap it for the one attached to the empty bays. I think the cable is the likely culprit. I put another new drive in the same bay today, and it also went device disabled om the UI. Its gonna be a PITA tho. I have remove the fan wall the Norco to get to the cables. Will do tonight or tomorrow. Quote Link to comment
trurl Posted March 10, 2016 Share Posted March 10, 2016 You have a plugin, Aesir, which to my understanding is an incomplete work in progress. Probably not the issue but you might try removing it. Quote Link to comment

I ran the Long smart test and it completed without errors. You ran a short SMART test, you should run the extended test. BTW, all you other Toshiba disks have a lot of realocatted sectors, not a problem per se but keep an eye on those values. Quote Link to comment
batt01 Posted March 11, 2016 Author Share Posted March 11, 2016 I looks like the cable was the issue. Parity sync is in progress for a couple of hours. Before with the other cable, it would disable the disk after a half hour or so. This is what you get when you buy the cheapest cables you can fine. These were 15 bucks. Saved a few buck in exchange for hours of aggravation. Thanks very much for your attention and help. Quote Link to comment
