April 13, 201511 yr That disk looks fine. All drive encounter raw read errors ... Seagate reports those, but it's not an issue. ... and the fact the temps changed doesn't matter -- they still look fine. (It'd be surprising if they didn't change )
April 13, 201511 yr Author First totally new drive I've used so wanted to make sure about the raw_read stuff, I know the temps changed don't really matter (unless they go freakishly high). Thanks!
April 15, 201511 yr No sectors re-allocated which is the big thing. I agree that looks like a good drive. Good luck!
April 15, 201511 yr since we are on the subject and I dont feel like starting a new thread over a simple question, is Command Timeout of any concern either? Event: unRAID Disk 1 SMART health [188] Subject: Warning [TOWER] - command timeout is 237 Description: ST31000528AS_9VP24Z8H (sdc) Importance: warning Its always been at that value. I think SMART values clarifications should be added to the wiki.. by someone who understands it better than I do.
