@obaiamr139 -- wear level is 6%   -- what does that mean?

Compare to a brand-new automobile tire. Measure the depth of the tread. 

Drive a few thousand KM. Remeasure.

Do you get a measurement that is 6% less than the original, as the tire is wearing out?

Typically, the wear on the tire is the same percentage, no matter where on the circumference of the tire that you measure.

The same "wear level" applies to the SSD.  The "cells" that store values have a "lifetime".  Update the value in the cell a few million times, and that cell will be 100% worn-out.

The value for the SSD is an "average" value, measuring the remaining "lifetime" for the entire SSD.

But, in your case, you have a specific error -- like a nail going through an automobile tire -- that directly affects some cells on the SSD, and indirectly affects the "health" of the entire disk-drive.

Your only solution is to replace the disk-drive, like replacing an automobile tire when the tread-level is very low.

Note that the "3F4" is the label for one of your connected disk-drives (or CD/DVD) drives.

Usually, "3F0" refers to the 1st SATA socket on the motherboard, and "3F1" refers to the 2nd SATA socket.

So, seeing "3F4" means that the device connected to the 5th SATA socket is the problematic device.
