A wild guess but it looks like possibly an MTU issue.

You could try a cold boot but, ultimately, I would replace that drive and rebuild the data. Perhaps try the bad drive in a separate computer running another copy of unRAID to see if you can retrieve the data.

Currently the cheapest 4TB in Canada. Inside is a WD Green. Deal is in-store only as it shows $179.99 on the website: http://www.costco.ca/.product.100084283.html I bought 2 for myself.

It's $149.99 on the Canada side but you can price beat it with Memory Express (184.99) and get it for CAD $142.49.

You ground the green wire. There are plenty of instructions out there. You just use the rocker switch on the power supply to control power.

I went the cheap route and modified a power supply to be always on. The power supply powers all my drives and drive cooling fans separate from my server. I can still see where there could be a use for this product though.

I have an old Areca ARC-1170 and use a Seagate 4TB as my parity without issue. If there's anything you want me to check/compare, please ask. I have my controller set to JBOD.

In all honesty, removing the drive from the enclosure is probably going to make the drive last longer anyway.

Here, I'll give you probably more than you're asking for.

I've never tried running in RAID mode but I'm assuming that's where passthrough would be used. Drive temperatures aren't reported in unRAID but the card monitors them directly and emails me if there are any drive issues. The Main tab in unRAID shows my first 2 drives as such: Parity 20004d927859eb810 (sda) 3907018532 * 4 TB - - 12,866,224 2,296,820 0 Disk 1 20004d927859eb820 (sdb) 2930266532 * 3 TB 2.90 TB 100 GB 6,221,984 288 0 System Configuration: System Beeper Setting Enabled Background Task Priority High(80%) JBOD/RAID Configuration JBOD Max SATA Mode Supported SATA300 HDD Read Ahead Cache Enabled Volume Data Read Ahead Normal Empty HDD Slot LED ON HDD SMART Status Polling Enabled Auto Activate Incomplete Raid Enabled Disk Write Cache Mode Auto Disk Capacity Truncation Mode No Truncation I haven't really played with the above settings other than disabled NCQ. I tend to not tinker when things are working. My last parity check: Last checked on Thu Nov 7 05:33:52 2013 CST (yesterday), finding 0 errors. > Duration: 15 hours, 46 minutes, 50 seconds. Average speed: 70.4 MB/sec The 100MHz PCI-X bus speed is good for 768MB/s theoretically and I've seen over half that when preclearing 3 drives simultaneously. My Dell PE 1600SC server is powered by 2 Xeon 3.2GHz processors. SL7AE if I remember correctly. If you want to know anything else, please ask.

Does a customer who buys 2 keys count as one or two?

I have encountered SAS controllers which will only work in workstation class motherboards. The one that comes to mind was an HP brand but perhaps your card does the same detection.

What vl1969 said. I preclear my drives on a separate system then add them to my server. The server sees the drive as precleared and it's a quick add to the array. The Areca card does not modify the drive data in any way when I plug it in. This is for JBOD. I never checked with the card in RAID mode if you would have to create an array for each individual disk. I remember having to do this for SCSI RAID controllers.

I'm all for reusing old server hardware. I'm running 10 drives so far on an Areca ARC-1170 in a Dell 1600SC server. I got the server for free and the card for a reasonable price from a popular auction site. The card has 24 physical SATA2 connectors and supports the 3TB and 4TB drives I have plugged into it. I really like the built-in web interface it includes through its built-in ethernet port.
