Please post full hardware, OS version and other details on your system. We can only go off what you posted and there is very little info. Can you be more descriptive about where or when this error is occurring?

Welcome to the community.

Looks like your drive ada0 has an uncorrectable error. Run smartctl -a /dev/ada0 and post the results. You can also take a look at the Drive Troubleshooting Flowcharts in my signature. It will guide you through this.

And as @SmallBarky said, post your system specs and any more details you can discover. The flowcharts will help a lot here.

It’s Freenas 11.1.U6
MB Intel

I’ve a lot of errors and I can’t type anithing.

How can I type this command?
Can I boot Freenas or other by USB key?
Or remove the broken drive?

Thanks

You need to be more specific. “lots of errors” doesn’t tell us what errors you are talking about.

Why can’t you type a command? Are you at an SSH screen or Shell?

Of course you can boot FreeNAS on a USB key.
