Upgraded to Monterey - Can't Read my External Hard Drive

This is why upgrading is a bad idea. You end up wasting all of your time 'solving' problems that just weren't there to begin with. Yeah, so, anyway, how the flip do I just read my external hard drives?

Looks like there's no fix for this massive shortcoming of Monterey. This is why you should never upgrade.

You bought it through Apple but it's a LaCie drive and how it is formatted and whether you installed any LaCie utilities or firmware for that drive is important because those things often also need to be upgraded to a version that is compatible with the new MacOS. The safest thing is to erase/format the drive when it is new, with Disk Utility (not some other third party utility), formatted as GUID and APFS. Are you using LaCie's disk utility software or package with that drive?


Again:


How did you encrypt the drive? Was it through Apple's software or through third party software, e.g. utilities that came with the external drive? What is the format of the drive (e.g. HFS+, APFS, NTFS, ExFat)?


If you encrypted the drive with third party (non-Apple) software or utilities, or the drives are NTFS and require special software or firmware to be recognized, you may need to update that software to a version compatible with Monterey.


I am using external drives with Monterey from Western Digital, Samsung, G-Drive, Seagate, Apricorn, and an old Buffalo external drive. All have worked fine so I am thinking there is something installed on your Mac that is conflicting with Monterey.


If you download and run Etrecheck, and post the report here using the Additional Text button below, people reading this thread can inspect that report (it is anonymous about you, it does show what has been installed) and hopefully quickly identify the culprit. If it is an outdated driver or firmware for the external drive, that is usually quickly fixed by getting the updated version that is compatible with Monterey.

Hey silver_mica!


Regarding your response to tbirdvet, it might not me mounted, but if you open Disk Utility and click > View > Show All Devices, does the top level hard drive show up?


Another good spot to check is Apple > About This Mac > System Report. As far as the hardware is concerned.


Can you say exactly what the error message is, if there is one, and when it occurs?

I'm not sure what you mean by "hub". This is just a normal external hard drive - a LaCie Hard Drive connected through the old USB type ports (not thunderbolt 2 and not USB C (I think it's called)). I have a 2015 MacBook Pro.


It would have been thoughtful if I was given warning during the install of Monterey that EVERY external hard drive would suddenly stop working with Monterey. This is why I'm very reluctant to upgrade.

I'll check Disk Utilities later tonight - but, I can already tell you that the drive will not show up under Disk Utilities. Last night when attempting to mount the drive I opened Terminal and looked under the /Volumes directory - the external USB drive wasn't there. But, that was expected since the drive is encrypted and you first need to enter the password to mount the disk. The opportunity to enter a password never presented itself - because Monterey is dysfunctional . . . the ability to mount external drives (that I've been mounting for 5+ years) has been lost. This is why you should avoid upgrading.


Also, erasing the drive is not a solution. Does that really need to be said?
