Two APFS partitions on an external SSD disk will not mount. Happened after install of Catalina.
Prior answer on this forum was "if all efforts fail, copy the information and reformat".
questions:
How do I copy files from a disk that will not mount? I missed that tutorial.
what exactly does this information mean? original answer was not informative.
iMac 21.5″, macOS 10.14
Resolved, for now, with iBoysoft data recovery. not ideal, but I have my info back for $100. Thanks for your interest and help. I very much apprececiate your last response: responded accurately to the original question and helped me look for practical solution. I also looked a lot of places and couldn't find an answer before posting here.

Okay.
If you have a Windows machine then try mounting the drive on Windows, copying all your data, formatting it and then using it with a Mac.
To mount APFS drives on Windows, you will need a third-party app.

Disk Internal's Linux Reader is one of the few softwares available for reading APFS on Windows. If you don't want to recover your data, you can format the drive from Disk Utility on a Mac or from Disk Management on Windows.
It looks like there isn't a fix for Error 49218 yet.
Thanks,

Thank you, Vivek. that goes to my first question.
Can you answer the second:
What exactly does "com.apple.DiskManagement.disenter error 49218:" mean?
I'll give the windows approach a shot. Parallels doesn't do it, I assume ...

Hey,
I checked a lot of articles but couldn't find info on what the error 49218 means. It seems like Apple hasn't elaborated on the issue. One guy contacted Apple support and they suggested him to do a full factory reset, but then his Mac stopped booting.
Like I said before, there is no official fix yet. You can try using Disk Drill, it's a data recovery software. You can also try emailing Tim Cook at tcook@apple.com. The email address is maintained by a really good support team which will almost certainly fix your problem.
Thanks,
Vivek
Hey,
It looks like your external drive is encrypted. Does Disk Utility ask you to enter a password?
Thanks,
Vivek
It is not encrypted and no, it doesn't ask for a password. worked fine until Catalina. Which also bricked another mac with the firmware ID request since I can't find the receipt for it.
