Running unraid 4.7

My Specs are the same as Eskro's 20 drive array he posted in the forum with the exception of a higher watt power supply.

 

seeing some weird errors in the syslog. Is this a bad drive? Or possibly a bad power connector or sata cable? Maybe a bad connector on the addon card?

 

Here is how it went down:

The first time:

I originally had the drive plugged into P2 of my 4 port SAS Cable. i tried to preclear the drive it produced 4GB of errors in about 15 minutes in the syslog and locked up the server, but i believe this was due to a bad power connector or SATA cable as i plugged the drive in to my windows computer and ran check disk and it seemed to finish okay. i have a drive plugged into P1 on the same SAS cable that works fine so i believe the connector on the addon card is good so it might just be that P2 is the problem.

Here is the logs from the first attempt: http://rghost.net/private/45200731/9eeca3bb225bdac0509ee0287a3a39bd (NOTE: unzipped these files are a whopping 4GB so make sure you have enough space. you will also not be able to open them with notepad it will throw an error. google LTFViewer 5.2 for a good program to use).

 

Second Time around:

i swapped out the SATA cable (ditched the SAS altogether and used my last free port on my 2x SATA addon card) and the power adapter, ran a short smart test (which passed) and the drive is nearly done pre clearing now but i'm still getting intermittent errors that are different from the first time around. See log file attached to Post.

Also of note for a while on step 1 of 10 of preclear the MyMain Smart View for unmenu was reporting 33 bad sectors though now it has disappeared for some reason.

 

Thoughts? Should i just RMA the drive to be on the safe side?

Any Suggestions would be helpful.

Post a SMART report for sdd.

The Post read on the drive is at 83% i will post results of a long smart test as soon as it is finished.

Preclear is done and log is attached

That does not look good - there are lots of pending sectors which should not be the case at the end of a pre-clear.

Yea i figured as much. I guess ill RMA it out. So the bad sectors in the drive is what was causing those errors in my 2nd log? or do those indicate another issue?

The media errors are the un-readable sectors.

 

RMA the drive.  As already said, there should be no sectors pending re-allocation after a preclear.
