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!

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.
