mushtafa Posted July 13, 2020 Share Posted July 13, 2020 I've just bought 3 second hand HDDs. SMART looked good, so set about setting unraid up. I've filled 1/3 of one the discs and it's now reporting an error on the dashboard. Checking the attributes of that disc I get "197 Current pending sector". From my reading, this is bad. How can I fully test this, and other 2 drives? They are setup in an array, but it doesn't matter that the data is lost and I have to start again. I've been reading about 'preclear' but confused. That can pre-clear any disc that isn't part of the array. My discs are part of an array. Is preclear the way I need to go with this? If it is, I'll post in it's support thread for help. Otherwise, can anyone suggest another way? Quote Link to comment
JorgeB Posted July 13, 2020 Share Posted July 13, 2020 Run an extended SMART test on each disk. Quote Link to comment
