Hello, I'm using a WD my passport air 1TB on macbook air. Yesterday it got disconnected without ejecting by accident and this morning, it failed randomly. I now cannot mount the drive anymore, it does appear in system information on my mac, but not in disk utilities. I tried using data rescue 4 to no avail. I tried using WD drive utilities as well, which sees the drive but says "no volume found". I therefore cannot run a SMART test or anything on it. Please help, I have no idea where to look anymore -- i have been on help and support forums all day looking for a solution to a similar issue without being able to. I have VERY important data (300GB of my travel videos and photos) on this drive and I am very scared to lose it. Thanks in advance for any advice!
