There are certain file formats that you’ve got the option to select when formatting the drive.

If you plan to use the drive on the Mac only, selectAPFS.

For older Macs, selectingMac OS Journaledwill do just fine.

However, chooseFATorexFATif you intend to transfer files between Mac and Windows computers.

This way, the SSD will be recognized by both OS.

Once the formatting is done, you could finally reach the drive from the Finder app.

If the drive still does not appear, try formatting it on a Windows computer.

To do that, openDisk Management>Right-press drive>Format.

In that case, return the drive for a replacement if it is covered under warranty.
