What does a re-certified drive mean.
It means it was tested and found not to be working at some point when returned under Rma procedure to Seagate.
Where part of the drive could of have failed, or developed an intermittent fault.
But the part of the drive such as the circuit board that controls the drive has been replaced.
If the drive is reporting it is not ready, it means there is a problem in most cases with the I/O part of the drives circuit board .
Or the Sata interface, connector on the drive Nate.
Double check the Sata data cable to the drive is firmly connected to it, and the sata motherboard connectors.
And also power to the drive.
Or try using a different sata cable with the drive.
The error is mostly down to a bad data...
