Thank you very much for your comment. We will gladly forward this internally to the responsible department and hope that this will be checked promptly.

I just received the Extreme Pro Portable V2 with 4000 GB in the post today and immediately tried to format it to MacOS Monterey. On my Intel (16' MBP 2019) it didn't work at first, because Disk Utility mounted the disc again after erasing and formatting. This failed and the result was that the SSD was formatted as MacOS Journaled. Found out afterwards that if Parallels or any piece of non-Apple native VFS kernel code is running, the remount falls flat on its face.

On my M1 (14' Macbook Air 2020) I was then able to format the thing to AFPS without any problems. So I can confirm that it runs on both architectures with two different Macbooks with MacOS Monterey. The SSD can definitely be formatted!

I formatted the SSD with the iMac with APS, then plug it into the iPad or iPhone with a USB C or Lightining, but it doesn't show up as a drive under Files? What am I doing wrong?

Hello Rolf, I have exactly the same problem, the disk is NOT usable with MAC Monterey ... have lost all data, the disk just disappears and is no longer shown as a volume. All data was gone. Thanks for the information !!!

Have you tried formatting the drive in the terminal with Diskutil? Maybe partition it first?
