Rob here. I ran the test and got this. SMART Self-test log structure revision number 1 Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Extended offline Completed: read failure 20% 1863 - That sure doesn't look good. I took it out of my BTRFS array because there were millions of wite errors. Sounds like I acted none too soon. ----- Original Message ----- From: Linux for blind general discussion <blinux-list@xxxxxxxxxx> To: blinux-list@xxxxxxxxxx Date: Fri, 5 Apr 2019 08:23:25 -0500 Subject: Re: SMART Errors: What does it mean? > Tim here.
