Yesterday I accidentally pulled out the plug to my external HDD (My Passport Air) while it was still ejecting. I thought it was finished but it wasn't. A few hours later I plugged it in again and it seemed to be working fine. This morning I plugged it in and now it's not mounting on my Mac. It shows up in Disc Utility and Time Machine still recognizes it but I can't access any of the data on the drive because it doesn't show up in Finder or the Desktop anymore. I know I did something to cause this when I pulled out the cord too early, but I don't know what my options are now to fix this. I'd prefer to save the data obviously, but even just getting the drive functioning again would be nice.
