Question: Well, this is a bummer…. I just cracked the SATA power connector on a large 5TB HDD! It’s still working and I have it plugged in, but I’m sure if I unplug it one more time, the connector will go with it.

So what are my options here? Is this fixable or should I just start backing up important stuff and start digging a hole in my backyard?

Answer:First 3 pins serve the same purpose. As long as one of them is fine, drive will operate normally.
But since one pin is broken and other may not make proper contact, remaining pin will heat up more (may be even melt surrounding plastic).
So – make sure bent pin is straightened and making proper contact.
