Ok I have upgraded a few drives never had so many problems. I replace my 1tb parity drive with a new wd ears15 1.5tb after that I had nothing but problems. I did jumper the ears drive before I installed it. First the server would take about 15 minutes before I could access it through the web, then it didn't show all my disk. Turned it off checked all cable rebooted it showed everything but the new drive had a orange ball nextt o I think and there was a format option, I took it as meaning I needed to format the new parity drive to make it work, WRONG it formatted all 7 drives, I lost about 4 tb of data. It sucks but I am past it. After that mess I noticed that unraid was still running very slow. What I found is that with the 1.5 ears15 drive as the parity the system is slow and the parity check speed is an awful 150kb a sec. I am usually around 50000 kb a sec. Since I lost all my data I can't hurt anymore so I took that drive out an put in my older WD10EACS terabyte drive and everything is back to normal.

 

My question to anybody that might know is this, do you think the new ears 1.5 drive is bad, or could it be that the slower rpms is causing a bottleneck effect? Any help would be great. Ah time to start my movie collection all over again.

 

By the way if it helps here is the drives I have with it. 2 WD10EACS 1tb, 1 WD10EADS 1 tb, 2 WDC_WD5000AAKS

It seems likely to me that the drive is bad.  Did you preclear it?  What does SMART say about the drive?

 

Captain Hindsight to the rescue!  You really should have sought help here when you 'lost' your 4 TB of data.  It is very likely that you could have recovered it.  If you haven't written to those disks, you still may be able to recover it.

 

Also, what version of unRAID are you using?  It sounds like you were bitten by the 4.5.3 unformatted bug.  You should be running 4.5.6.

No I did not preclear it, I only new about the junper from a friend haven't ben keeping up with all this stuff, unraid had been so good never had a probelm in 2 years. When I lost my data I was running 4.1 something. I upgraded to 4.5.3 today, guess I need to go to the next release.

 

I have not writtin to any of the disk yet, I figures when it formatted the drives everything was cleared. I do not know much about linux so please excuse my ignorance, but if there is a way to try to get please let me know that would be HUGE time saver.

 

I run my unraid headless, but have monitor I cna hook up to it if needed.

How did you get 4.5.3?  That release was pulled from the downloads area quite a while ago.

 

Yes, you can get back your files... most of them actually as long as you did not write to the disks.

 

The technique is here in this thread:

Good luck.  Read through the above thread.  The user had the same bug bite them.  I provided guidance to him too.

 

Ask questions if you are unsure.

As for the EARS drive, run SMART on it and post the results here.  Here's how to obtain a SMART report.
