freenas.local smartd 1114 - - Device: /dev/da1 [SAT], 8 Currently unreadable (pending) sectors

[cozd74]

problem: for some time I get this error message on my FreeNAS (TrueNAS-12.0-U7)

freenas.local smartd 1114 - - Device: /dev/da1 [SAT], 8 Currently unreadable (pending) sectors

dev/da1 is a 1TB external USB drive used by a Plex library

Proposed solution: http://bytesandbolts.com/fixing-freenas-error-currently-unreadable-pending-sectors/

I applied the proposed solution to my problem: attached the outcome of the checks of my disk

dd if=/dev/zero of=/dev/da1 bs=4096 count=8 seek=190056456

I tried to run the following command by setting bs=512 and then also to 4096 but the problem remains

how can I do?
thanks

Take the drive out and plug it into a real port.
Then erase the drive in some manner, making sure you write to every sector at which point the drive should reallocate the dead sectors
Wether the drive is still good is an answer you should consider carefully - throw every test you can think of at the drive
