Now that it's morning I found the problem, and you were on the right
track. Indeed, the filesystem was FAT32. The USB drive is a 128GB PNY
drive that originally arrived as FAT32, but I reformatted it to ext4.
Later at PSU I was trying to use it to get some files from another
student, but he said that Windows wanted to reformat it. Knowing that
there was nothing on the drive I told him to go ahead, so that is how
it got back to FAT32. Later I forgot the incident, hence my confusion
at not being able to copy large files to it.

I reformatted it ext4 just now, but afterward I cannot read or write to
it because it appears to be owned by root. (I used gparted to reformat
it, which requires sudo to launch it.) I did sudo chmod
777 /media/jjj/128GB (the new label), which executed without error, but
it still seems to be owned by root. 

My use for this drive is normally to transfer files from my two Xubuntu
computers at home (because I can't get NFS to work), or sometimes at
the Clinic. There is no reason not to set the permissions at 777. Can
someone help me with the chmod command so I can drag and drop files
with Thunar?
