I have googled and read a lot about this problem and I can't understad the impact and if there is any more actions I need to do to acknowledge the error (complete the reallocation?)
The questing is this an error or an indication that 2 sectors where reallocated to new space on the SSD disk?
if it's an error, how to fix it w/o destroying data
If its no error, how do to stop smartd report it as an error
I get this message each day from the system
