MPB doesn't recognize Sandisk SSD anymore

We occasionally see drives fail when they were not ERASEd when new, but the maker's Utilities, including Paragon or Tuxiera NTFS Drivers were installed. All proceeds fine until that Driver is not included in the MacOS image being used, then the drive 'mysteriously' stops working.

A drive set up by the maker as Windows New Technology File System (NTFS) can have MacOS Volumes created on it, either MacOS extended or APFS, when those Utilities are present. But when the Utilities are not there (a different Mac, a different MacOS, or something else) the drive won't mount. But It will show up in Disk Utility.

Open Terminal and type this command, which just lists all the drives and partitions on your Mac, including 'helper' partitions. It changes NOTHING:

diskutil list

copy the text or screenshot and post a picture.

<< I did plug the SSD into a PC recently and it read fine. Now my MBP doesn't recognize it anymore. >>

Look at the last line of the report:

It looks like the PC changed the partition TYPE, which is now "Microsoft Basic Data" partition.

MacOS has no clue how to Mount a drive of that partition-type.

It can create and read and write and format exFAT drives, a common PC format.

While you have it there, you might want to select the drive and Repair/First Aid

Select the drive and click the Mount icon.

if you get an error message, what error?

what kind of Drive does Disk Utility think it is? can you post a screenshot?
