I have an external SSD device which is randomly mounted in my MacBook Pro with macOS High Sierra (anyway, I had this problem even in Yosemite, it is not OS related).

I've formatted the SSD with Disk Utility app to NTFS because I need a drive readable from wherever. I do have the Paragon NTFS for Mac app (version 14.3.318), so I guess the filesystem is not the issue. I said so also because this morning, just after the format, I was able to copy stuffs to the ext SSD. But right now is not detected at all.

If I run in the terminal:

diskutil apfs list

I can only see the internal SSD

APFS Container (1 found)
+-- Container disk1 536C2ECC-3939-4732-9357-2F037669B42F
    APFS Container Reference:     disk1
    Capacity Ceiling (Size):      250790436864 B (250.8 GB)
    Capacity In Use By Volumes:   165896990720 B (165.9 GB) (66.1% used)
    Capacity Available:           84893446144 B (84.9 GB) (33.9% free)

What is going on?
Thank you for any help you will provide

  • @klanomath sorry, not iOS expert, what if I'm running High Sierra? Thank you for your comment! – user3861363 Dec 13 '17 at 16:38
  • Done! ProductName: Mac OS X; ProductVersion:10.13.1. So I have High Sierra.. How is this related to my issue? I did have the same problem with Yosemite – user3861363 Dec 13 '17 at 16:47
  • Ah ok, thank you. The Paragon NTFS for Mac version is 14.3.318 – user3861363 Dec 13 '17 at 17:00
  • Try to update to Paragon NTFS for Mac 15 - AFAIK the first version also supporting 10.13. – klanomath Dec 13 '17 at 17:09
  • diskutil apfs list will only show volumes formatted as APFS, not your NTFS disk. run diskutil list instead. – onik Dec 13 '17 at 17:47
