I bought a 2TB WD My Passport just several weeks ago and It worked perfectly until I started tinkering with its format. I formatted it to ExFat and It worked for a while but then my Mac just stopped detecting it. A popup suddenly appeared that the HD was disconnected and all my attempts to reconnect the disk failed. I was confused so I reformatted several times to NTFS, ExFat and HFS+ thinking it was a format problem, now it barely works at all when I plug it in my Mac (takes a lot of plugging in and out and the light lights up but doesn’t show up in Finder) yet it works flawlessly with my PC.
Was I too harsh with it? I usually leave it connected to my Mac all the time to download things while also playing media. What am I missing?
