Q: Is it possible to use internet recover from an Ethernet connection
Attempting to use Internet recovery on a mid-2010 iMac.
IT tells me it will take a while then prompts for a WiFi connection.
I Have a direct Ethernet connection, but I never get any option to use it.
iMac, OS X El Capitan (10.11), iMac Core i7 2.93GHz 4GB

If you were getting reported S.M.A.R.T. errors, you disk is dying. You should be replacing it. But the time correctable error counts get high enough for S.M.A.R.T. errors to be reported, the disk is generally getting ready to fail.
Make sure you have backups of your data (which I'm assuming you do, if you reformatted already).
This thread seems to have the most information I've found on 1005F
If you have WiFi available, unplug the Ethernet cable and see if Internet Recovery will proceed over WiFi.
After that, if you have another Mac, download El Capitan (assuming you do not already have a copy), and create a bootable installer (USB thumb drive, or external USB disk, etc...)
sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app --nointeraction
