how to delete items from seagate back up drive

[needing help]

I have a seagate back up drive that used to work perfectly well. But after I upgraded from Yosemite to High Sierra, I can no longer delete files off of it. I can add files, but will not allow me to delete. What can I do?

What -format- is the drive in?
HFS+?
Or... something else?

Do you get an error msg when you try to delete a file?
If so... what is it?

It says format is windows NT file system (NTFS). Can I change the format without wiping out all that is saved? That is probably the problem, I am guessing? And there is no delete option even. There used to be, but not anymore. Not sure why

"It says format is windows NT file system (NTFS). Can I change the format without wiping out all that is saved? That is probably the problem, I am guessing?"

I'll reckon that's the problem.
You need to reformat the drive to Mac OS extended with journaling enabled.
You can do this with Disk Utility.

BUT...
You need to save all the files that are currently on the drive TO ANOTHER DRIVE for the time being. They're gonna get wiped out if you don't.
So... copy all the files to another drive, somewhere safe.

Then... erase the problem drive.
Then... copy the files back to it.

Sounds like the best plan. Thanks for your advice!

You had to have some third party SW installed for NTFS support, as macOS's NTFS support is read-only (and always has been).
