This is very concerning. I wonder if you have a fake USB drive. If
that's the case, then you can consider your data gone. And it often
doesn't fail until you've written a certain amount of data. Or possibly
also read a certain amount which is likely what happened in this case.

If this or fdisk doesn't return any partitions, then there's no point
trying to mount it.
Try running "gpart /dev/sdb" again. If it still finds the FAT32
partition, then run "gpart -W /dev/sdb /dev/sdb".
Assuming that's successful, try "lsblk -f /dev/sdb".
If that still shows the partition, then try mounting it.
If that fails, show "dmesg | tail".
# gpart /dev/sdb

Notes:
Last week, before I did the defender scan that windows recommended, I
did get a few files off the stick. I got all that I tried. I did not
try most.
Between doing fdisk (late last Friday) and
"What happened to the partition?" (this afternoon)
I tried to see if windows sees the stick. As far as I know, I did
nothing that would have windows write to the stick. But might it have
written to the stick without us knowing?
Breaking news?...
Looking at last Friday's posts again, I see that you had me try fdisk,
which I did do on Friday. That hasn't been tried today. Is that what
produced output suggesting some sort of a partition on the stick? I
just tried it again. The results:

Does that change the picture?
