Hello, transferring data from a Mac to an NTFS (Windows NT File System) drive can be a bit tricky because macOS can read NTFS drives but cannot write to them natively.
Here you can accomplish this task by using an NTFS driver for Mac.
You are suggested to try iBoysoft NTFS for Mac, which enables write support on your Mac.
You can also transfer the data from the Mac by formatting the NTFS drive to a macOS-compatible format like exFAT or FAT32. Keep in mind that formatting the drive will erase all data on it, if you lose, you can use iBoysoft Data Recovery for Mac to recover them.
Hope that you can succeed in transferring the data finally.
