Your data is fine. The usb drive is bad. Replace it.

Hi paleoN,

Thank you for your reply.

I'm glad to hear that my data are safe :). Unluckily we don't have a configuration backup.
There is a way for get a configuration from old usb?

You could try and mount the USB in a different system, something that knows UFS, and see if you can pull freenas-v1.db off it.

You could also just install FreeNAS on another USB, boot from that, insert old USB disk, go to the command line and mount the old partition, and then copy the database to your /data directory or some other folder.
