I have 3 1TB WD green hard drives in a 4 bay Probox. I was just doing some editing and the power went out but my PSU's battery just recently died so everything shut off but it was only for about 1 second. I reboot my mac to find my hard drive that was named External 2 now named External 1 and has no files that were in it and only the folders and names that were on my external 1. I have no idea what happened but apparently it somehow copied just the folders of my first external and deleted 800gb of video. I went to verify in the disk utility and it said that it needed to be repaired immediately. I did that and it didn't do anything that i have noticed but it says the drive is completely fine. Any ideas on what has happened? or if my data would still be on the hard drive somewhere?
