While my iMac (OS X El Capitan version 10.11) was in sleep mode the other day I stupidly unplugged my external hard drive from it in order to bring it somewhere. I should have properly ejected it but I didn’t and now when I plug it back into my computer it isn’t readable and I get an error message that says “The disk you inserted was not readable by this computer” and my options are “intialize” “ignore” or “eject.” I selected “initialize” and it brought me to disk utility:
