WD20 EARS possible failure

My problem drive is a WDC WD20EARS
On startup I am informed - “SMART capable and status bad”, and “SATA port 3 Device error”. On attempting to search the drive it is extremely slow or reports no response.
Question - Is my drive in danger of failing completely?

Time for a new hard disk, your disk is 2009 vintage. Might want to use 2 or 3 disks for more redundancy.
