Thanks for taking a look, it is very much appreciated. I will move the NAS drives around to get them in front of a fan. sdf and sdd are the 2 WDC_WD30EZRX drives... Might be best to give up on them...

Hi All, Done a big batch of preclearing - can anyone please look at the 3 reports below? The first two are from brand new Seagate NAS drives - have I got lemons?

WDC_WD30EZRX preclearing after 46 hours (one 89% of copying zeros and the other at 3% of the post-read) (sdd and sdf). I have previously had issues trying to preclear these a few days ago where they got stuck late in the post-read process. A third drive I have of exactly the same type successfully precleared after 37 hours with no issues. Attached is a link to the errors and minor issues in the syslog. These drives look like they are in a world of pain. Should I write them off? https://www.dropbox.com/s/wg36u841ijo9of3/SysLogExtract.txt Sorry for the long post... Any help is very much appreciated

Great, will keep them on! Thanks Joe

Quick question I am about to preclear 9 hard disks (ranging from 3tb to 1.5tb) on a AMD A4-5300 Dual Core 3.4Gh with 4gb of ram. Based on reading the configuration tutorial, I intend to use the following command to run the prelcears all at the same time (in separate screen sessions): preclear_disk.sh -r 65536 -w 65536 -b 2000 -A -m [email protected] /dev/sdX Do I still need to have the -r, -w and -b variables and will these effect performance? Note: I am using the v1.14 of the script and I have selected MBR-4k-aligned in the unraid settings. Thanks for your help!
