I erased everything on my mac and reinstalled.
Then I connected my hard drive, but nothing showed up.
I downloaded utilities and stuff from WD website but nothing happened.
I read some articles and was trying solutions.
I accidentally formatted it by using Partition in Disk Utility.
Luckily my storage still says I have 2 TB left out of 4TB (so I assume my files are still in there).
BUT I still don’t see my files yet now I see the partitioned portion only.
If anyone knows how to fix this, please let me know. Thanks.
