Thank you! To complete the record, the "permissions" option seems to have been the ticket. I just hope they're sticky ;-) On to the next problem.
I have a new (to me) system that has a 500GB SSD and a 4TB HD. I have windows and Ubuntu 24.04.2 installed on the SSD (SDA), and want to put user files on the HD (SDB). In order to share the HD I left it NTFS. Now I want it to be /home, so all user files go to it. I've been playing around for quite a wile, and can't get it mounted R/W. Finally leaving aside all the Q&A that applies to several different releases, I went to the man file for NTFS-3g,
I ran "powercfg/h off" in win, as mentioned in the man page. My most recent shot at /etc/fstab is below. If I don't have this entry in fstab I can access the drive just fine from Nautilus, create and edit files, etc. I think I'm just missing some magic incantation in fstab. TIA.

# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
