Cannot mount USB hard drive I have a 4TB USB hard drive (WB Elements) that I want to mount On a Macintosh Pro 16.
Unfortunately it cannot be mounted and the Mac does not show up any error messages. It also does not show up on &quot;Disk Utility&quot;. This same hard drive mounts easily on a linux system and data can be accessed. What is puzzling is that I could mount it a few months ago.
On that same Mac, a 2TB USB hard drive could be mounted. Any ideas on how to proceed?
I have a 4 TB WD drive connected to my iMac running High Sierra (now Catalina) and it works fine. There is a 3rd party app named Mountain that will mount troublesome volumes (or it has for me). If you download from the developer site you get a free trial period. Should be worth a try.
