I use 'blkid' that is part of the util-linux package on Debian, I don't
have a vol_id here.

Could the problem be that you've changed your external drive to vfat?

I just tried a USB stick formatted with vfat, at first 'blkid' didn't
report any information for it (maybe blkid is using a cache, or maybe
it's ignoring vfat partitions), but then ran 'blkid -p /dev/sdg1'
("low-level probe") and it reported the UUID and other attributes just
fine and mysteriously, subsequently running just 'blkid' now reports the
data.
