My 'WD 1TB My Passport' external HD recently has major issues. It's HFS+partitioned as 700/300GB, and left plugged into the rear USB2.0 of my 5th Gen Airport Extreme. I've been accessing it via WiFi for 2 years, backing up all my Videos/Photos and playing movies. Couple days ago the Extreme flashed orange, and the desktop drive icons turned Orange. I used Mac Disk Utility, and the secondary 300gb partition had errors. I erased and reformatted the secondary partition, and then backed-up all my photos using the Flickr up-loader. Today I went to backup my videos, but it mounts maybe 1 out of 3 times, and is too slow to actually bring any files up. I downloaded the WD Mac tool and it failed the tests, as it really doesn't mount. Then I brought it to work and tried the Windows 10 tool, but it doesn't mount nor recognize it, even through Windows 10 does. Where should I go from here? These video files are precious travel and life videos. I really would like to recover them. Any tips are appreciated!
