Spuds Posted January 13, 2016 Share Posted January 13, 2016 I'm very new to unRaid and have just finished preclearing (using the preclear plug-in) 3 6tb WD reds. 2 came back perfect but the third came back with some Seek Error Read info which I dont understand. Should I be concerned? I have express RMA for another 2 weeks on this drive so exchanging it shouldnt be a problem as long as this problem warrants an exchange, could this just be bad cable? maybe I can re do the test using a different cable, 56 hours to preclear though...... I appreciate any help I get, Thanks. Also, am I finished with the preclear process or is there another step I should do before creating the array and starting a parity sync? THANKS! ================================================================== 1.15 = unRAID server Pre-Clear disk /dev/sdb = cycle 1 of 1, partition start on sector 1 = Disk Pre-Clear-Read completed DONE = Step 1 of 10 - Copying zeros to first 2048k bytes DONE = Step 2 of 10 - Copying zeros to remainder of disk to clear it DONE = Step 3 of 10 - Disk is now cleared from MBR onward.

CHBMB Posted January 13, 2016 Share Posted January 13, 2016 Spuds, Best to post your results in this thread here dedicated to the preclear results... Sometimes takes a day or two before someone comments, but you may be able to find some more info on your issue by searching in that thread as well. trurl has a good link in his signature on how to best use the search function (It has some quirks) Welcome to the forums. EDIT: Here's the search post from trurl... Quote Link to comment
