how can I identify a defective internal hard drive that needs replacement on an early 2009 macpro running el capitan
Mac Pro (Early 2009), OS X El Capitan (10.11.1)
A good place to start is System Information (Option key down while clicking Apple Menu). In Hardware, click on SATA/SATA Express and look for SMART status in the bottom right pane for each HD listed in the top right pane. Unless the status is OK, it won't say Verified. If the drive is totally dead, look for a missing listing for a drive bay you know is filled.

🙂perfect answer which gave me exactly what I needed to know. and confirmed that the disk in question is failing and needs replacement even though it started to work again after many habilitative steps..
Glad to help.😉
This might be a good time to switch to an SSD. There's a sled made for your Mac Pro which will fit an SSD perfectly, and with El Capitan, it's easy to turn on TRIM for third party SSD's.
