Some might regard this as "ok", but I wouldn't. The Raw Read Error Rate is non-zero, heck over 130billion, seek error rate doesn't look good, Total blocks read is less than 3X the correctable read error rate. Going through a correction for 1/3rd of your blocks seems, AT LEAST, like it would be slowing things down, and would seem risky. On a good disk those error rates would be at or near zero. But your disk is falling back to EDD correction over 1/3rd the time now. That doesn't sound good to me... but maybe I'm more paranoid. My motto was at first sign of disk corruption (even correctable), replace the drive. You don't want to wait till it is "uncorrectable", trust me. Basil Chupin wrote:
I just ran smartctl on my 2 drives, sda and sdb, with the following results. Could someone please interpret these results and tell me if there is cause for worry.
