Vaseer Posted February 23, 2015 Share Posted February 23, 2015 I have trouble preclearing 3TB WD RED (~1 year old). I was using this HDD in Ubuntu Server with no trouble for ~1 year. Now I switched to unRAID and bought 2 additional 3TB WD REDs which are fine and preclear was done without error. When I try to preclear "old" 3TB WD RED, unRAID freezes when preclear come to ~250GB (Disk Pre-Read), write speed drops from ~130MB/s to less than 1MB/s. unRAID GUI is unresponsive, even if I stop preclear there is no response - I have to stop array from terminal and shutdown PC on button (command "powerdown" or "reboot" via terminal do nothing...). Only difference between preclearing "new" and "old" HDDs is, that for "new" HDDs I was connected to unRAID server via telnet and for "old" via SSH. I used Hiren's Boot USB to do HDD test - Conveyance self-test and Short self-test logs are attached. Currently I am running Extended self-test. In Short self-test I got read failure, but I don't fully understand what it means. Please advise. Thanks *Edit* - Added Extended self-test Conveyance_self-test.txt Short_self-test.txt Extended_self-test.txt Link to comment
c3 Posted February 23, 2015 Share Posted February 23, 2015 The file you are looking for is syslog (ie /var/log/syslog). But your disk is bad as indicated by the reallocated sectors and read errors during the short tests. Link to comment
archedraft Posted February 23, 2015 Share Posted February 23, 2015 Yup, your drive is bad based in the reallocated sector count and read errors after all your smart tests. RMA the drive. Link to comment
