Eject and disconnect it, restart your Mac, reconnect it and try again.

Also what Format and Scheme are you wanting...?

If you want OS X Extended for the Format select GUID Partition Map for Scheme.

If you want MS-DOS or ExFat for the Format select Master Boot Record for Scheme.

I'm wondering if it might not be the Samsung preloaded Software that is causing the problem...?

You do not need any drivers for any external hard drive; all you need is to format it correctly for Mac.

I may be off, but I believe it is El Capitan's Disk Utility causing the problem (if I remember correctly what I read) - have you tried to use recovery: boot into recovery (Command + R); once you see the Utilities window, try Disk Utility there to format it. Make sure to erase the drive and then format it Mac OS Extended (Journaled) and GUID partition scheme. You can use the Partition tab to do this.
