This is as expected. A device does not return a failed health status if 
(only) Read/Write error occured. It usually will return a failed status 
if the number of spare blocks for reallocation is below some threshold.

Smartctl will report a non OK health status if the device firmware 
indicates failure in ASC/ASCQ from SCSI IE log page (if supported) or in 
result of REQUEST SENSE command (see -H on smartctl man page).
