kingsheep Posted August 19, 2011 Share Posted August 19, 2011 I'm running Unraid version 4.7. One of my Drives generated tons of errors during updating the Parity disk and red balled. So I replaced it with another disk in the same slot but pre-cleared failed. I know it might be down to the cables etc.. but is there anything in the log file that can help see where the issue is? ========================================================================1.4 == invoked as: ./preclear_disk.sh -m [email protected] /dev/sde == == Disk /dev/sde has NOT been successfully precleared == Postread detected un-expected non-zero bytes on disk== == Ran 1 cycle == == Using :Read block size = 8225280 Bytes == Last Cycle's Pre Read Time : 7:19:39 (75 MB/s) == Last Cycle's Zeroing time : 6:28:40 (85 MB/s) == Last Cycle's Post Read Time : ( MB/s) == Last Cycle's Total Time : == == Total Elapsed Time == == Disk Start Temperature: 33C == == Current == ============================================================================ ============================================================================ ============================================================================ == == S.M.A.R.T Initial Report for /dev/sde == Disk: /dev/sde smartctl 5.39.1 2010-01-28 r3054 [i486-slackware-linux-gnu] (local build) Copyright © 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net === START OF INFORMATION SECTION === Device Model: WDC WD2002FYPS-01U1B0 Serial Number: WD-WCAVY0941964 Firmware Version: 04.05G05 User Capacity: 2,000,398,934,016 bytes Device is: Not in smartctl database [for details use: -P showall] ATA Version is: 8 ATA Standard is: Exact ATA specification draft version not indicated Local Time is: Wed Aug 17 22:45:50 2011 BST SMART support is: Available - device has SMART capability.

Joe L. Posted August 19, 2011 Share Posted August 19, 2011 First, update your preclear script. It is up to version 1.12, and you are 8 versions behind. Find the latest version here: http://lime-technology.com/forum/index.php?topic=2817.0 It might be the only issue, as it had an problem with newer versions of Linux and shell evaluation of numbers. Then, if it does not work, perform a memory test, preferably overnight. Other than that, it could be anything. (disk, power supply, motherboard, disk controller) Joe L. Link to comment

I'll give the memory test a try tonight plus I can also boot my main machine up as Unraid using the trial version and will run a Pre-Clear on the same disk and see what it comes back with.... Such a pain having all these variables but at least the disk it first failed as having Errors on was able to be read on another machine and the data extracted... You don't get that with a propitiatory RAID system, and the fact that the disk was readable on another machine may also point to the hardware on the first..... Joe L - I just followed the link you gave and can only see preclear for up to version 1.11 ? Link to comment

vca Posted August 19, 2011 Share Posted August 19, 2011 Sounds like your new drive might be bad, the last line in your SMART report: 200 Multi_Zone_Error_Rate 0x0008 195 167 000 Old_age Offline - 1030 is rather unusual, most of the posted SMART reports for these WD 2TB drives you see here will only have a raw value of 0 or maybe 1, but yours is 1030. Now I know this is one of the SMART fields that we don't know what the meaning of the raw value actually is, but your drive has a very strange value. I would suggest you put the drive in a Windows PC and install and run Western Digital's "Data Lifeguard Diagnostics for Windows" on it to see if it passes their tests. See this posting for some background: http://lime-technology.com/forum/index.php?topic=12789.msg121545#msg121545 I've had a few of these drives fail the preclear and in those cases the WD diagnostic tool declared them as bad even though the SMART report still said they were good.

kingsheep Posted August 20, 2011 Author Share Posted August 20, 2011 Cheers Guys. I'm running a pre clear first using version 1.12 of the script on another box to see if the problem has gone away, if it fails again I'll use the WD diagnostic tool and report back ;-) In the mean time i've been running a Memtest on my main box, i've attached the screen dump but all looks fine to me, please advise if I'm wrong.

kingsheep Posted August 22, 2011 Author Share Posted August 22, 2011 Well Pre-clear was taking such a long time on this drive >37 Hours!!! A non-enterprise WD 2TB drive had finished the preclear in 34 Hrs. So I started thinking maybe this drive is a bit on the slow side and decided to to try the WD Diag tool. This passed with flying colours.. so maybe it was a glitch, after all, just a slow drive? Link to comment
