SOLVED Need help with critical error, "Unreadable (pending) sectors"

[Muku]

Below is the screenshot of the error with my drive list in the back. Please tell me what is causing this error & how can I solve this?

The error is caused by SMART testing of the drive currently labeled as ada4
in your pool, pending unreadable sectors are generally an early failure indicator.
In MOST cases, replacement of the drive is the cure.

post results from
smartctl -a /dev/ada4

make sure to place the output in code tags.
Good luck!

It would actually be better to post results from this command instead, it will give us more information and protect your serial numbers:

Code:

smartctl -x -qnoserial /dev/ada4

Too late I guess on the serial numbers....as they are already in his image. :)

So, how bad it is? should I need to change my disk ASAP?

Seriously, this question comes up several times a week--apparently even looking at the other threads on the first page of the hardware or storage forums is too much work.
