I think your options are somewhat limited.

it is always best to use disk utility to erase and format a drive before use to remove any preloaded software. at worst it can render your data inaccessible. it can cause the software to stop working. when you use software from just about any manufacturer for their storage device you run the risk of that same software not being compatible with macOS updates / upgrades. The fact that you are using WD's software could be the cause of your issue. I have reinstalled the WD Discovery for Mac, but still the My Passport drive doesn't show up. When I click on the WD Unlocker all that does is tell me to 'run the WD Drive Unlocker application from the WD Drive Unlocker CD associated with the drive you want to unlock'. When I connect the MyPassport Drive the WD Unlocker symbol appears, but not the drive, which used to be the case before the Catalina update. Wondering if this is an issue with Monterey since the older coms are not running that OS and are working fine. Not sure what to do as the internet isnt helping solve the problem. It also still works on older devices.Ĥ) The other drive is brand new and nothing is working for that one to mount as well. ( error 49153.'ģ) I have run diagnoistics on the older drive and everything came back fine. Neither are working on the new ones.Ģ) I have looked in disk utility and I can see the drives but I cannot mount them.

No matter what I do I can not get ANY exernal drive to mount on any of my new Macbooks running Monterey.ġ) I have downloaded the WD discovery and utility which is the program that has helped my older macbook and imac mount the drives. I also bought a brand new external drive (WD My Passport- which is suppoed to be compatable with macs) as well as have my old external drive (WD My Passport) that has been working on my old mackbook 15in and my even older iMac for years. My Passport Drives not working on brand new comp I have recently bought a brand 2 new Macbook Pro 14in and its running Monterey.
