Why Can't I Write Data To The Formatted USB On My Mac?

Hi, I am reformatting USBs on Mac, I tried every format, and then did the adoption of Terminal to unmount and re-mount them since they are read only still. USB Get Info is showing ExFAT and Disabled in Owners, meanwhile, Terminal Info is showing Windows_NFTS. I tried Mac formatting on 4GB, 8GB, and 64GB USBs, but it didn't work, I still cannot paste anything on USBs. I have 10.13.6 High Sierra. Any fix, please?

It looks weird as the reformatting of the USBs doesn't work well on both the Windows operating systems and the Mac operating systems. I can only reckon that there is physical damage on your drives but it sounds irrational since you have several USBs at hand, after all, not all of them might be bricked simultaneously. My suggestion is to check whether you have a bunch of counterfeit USB drives from unreliable vendors, after that, you can go to Amazon to start the purchase of verified products, and then use them on your device.

This article on distinguishing fake SD cards might help you tell if a USB drive is counterfeit in relevant facets.

Furthermore, if you'd like to write files to an NTFS formatted on a Mac computer, iBoysoft NTFS for Mac is highly suggested, which mounts your USB drives in read-write mode automatically.
