So I plugged in my hard drive, and deleted a file on it, a .nfo file. I forgot I had a file in the trash and so when I ejected the disk, my mac prompted me an alert like "disk is in use" with a force eject button. I force ejected without thinking, because I really didn't think any of my files were in use (I checked the usual places like whether a video file was playing somewhere etc.) When I try to plug it back, I realise it doesn't read or appear on finder. I've restarted my computer and still nothing. Other hard drives work so its definitely an isolated problem. Any ideas?
Update: I can't do a Disk Utility repair? the option isn't even available
