Recover WD External Hard Drive Data on macOS Mojave

Query 1: Help, I’m in trouble. I lost my precious data from my Western Digital 2 TB external hard drive due to accidental formatting. Does there exist a solution through which I can recover my data from my WD external hard drive? Note: I am using MacBook Pro with macOS Mojave.

Query 2: Hello, my 2 TB WD My Passport Ultra external hard drive was not recognizable anymore when connected to my MacBook with macOS Mojave. The drive contained essential data, which I desperately want it back. I would appreciate any data recovery advice, thanks!


Knowing your Western Digital (WD) external hard drive is essential in recovering your lost data. Your hard drive is an electromechanical non-volatile data storage device that stores data permanently on a rotating platter coated with the ferromagnetic material. The magnetic head of the WD hard drive writes or reads data to or from the platter. These data are stored in a series of logical blocks or sectors.

macOS Mojave maintains the information of these files as metadata stored in the file system of the drive. When you delete a file, macOS Mojave updates its metadata information. Also, when you erase a drive, Mojave creates a fresh file system. In both situations, data stored in the sectors remain unharmed—This gives a chance for data recovery.

Mounting an External Hard Drive

WD external hard drive mounts on your macOS Mojave when you connect it to your MacBook. Mounting makes the drive available for use and is visible in Finder and Disk Utility. In case the storage drive is corrupt, the file system information is lost, which makes the hard drive un-mountable or unreadable on macOS Mojave.

The only way to create a new file system is by erasing the un-mountable/unrecognizable external hard drive with APFS or other macOS Mojave compatible file system format. Nevertheless, formatting also makes hard drive data inaccessible from macOS Mojave, and consequently, you lose those data.
