Hello, according to your description, maybe you mean whether the NTFS drives for Mac are safe or not.
Is NTFS for Mac safe? Firstly, you have to know the NTFS formatted drive can't be written but only be read on Mac, because it's only supported for Windows.
(1) If you have an NTFS-formatted drive that is no longer needed for Windows, it would be best to copy the data to your Mac or to another drive and reformat the drive to a more Mac-friendly format like APFS, HFS+…
But note reformatting will lose all the data.
(2) If you need to share data between a PC and a Mac, then using NTFS drives for Mac is a good choice.
