It actually depends on the process. What most people do not realize is just unplugging the computer is not enough to drain current/power. There can be enough juice left in the computer to kill a person after it has been unplugged; this is similar to how the old televisions used to work and how dangerous they were to repair without using appropriate precautions for the capacitors to drain.
On a computer, the proper procedure to make sure there is no residual current is to hold down the power button for 30 seconds after unplugging the computer. Computers have been designed so that this closes the circuit and allows all components to drain. If this was not done, it is possible that the unplugging and plugging in of the hard drive caused damage due to the residual current. However, I doubt this is the case since the hard drive was experiencing issues before the power was released and reapplied.
My question for slugger7 is: are you still having issues through the BIOS where the drive takes a long time to load or does not load at all? If this is still the case, and your hard drive works fine in an external enclosure connected via USB, I would start thinking this is a Motherboard related issue. Possibly a BIOS update needs to be applied, or the hard drive connector is bad.
You could also test by taking out your OS drive and connecting the other drive with the same connector if they use the same type. If you still have issues, that would rule out the connector, in which case you could contact Seagate and see if they have any troubleshooting steps as this would most likely be an issue with their drive. The drive may not be bad, but how it interfaces with your particular motherboard could be at fault, for instance.
