It's a journaled (ext3) filesystem, so when I next mounted it, it just
recovered the journal. e2fsck give me
allegro$ /usr/bin/sudo e2fsck -p /dev/sdb1
external: clean, 99789/19537920 files, 20715689/78142160 blocks
allegro$ /usr/bin/sudo e2fsck /dev/sdb1
e2fsck 1.42.12 (29-Aug-2014)
external: clean, 99789/19537920 files, 20715689/78142160 blocks

smartctl --health reports no problems. Though I don't know the smartmon
tools well; if there's some other check that makes sense to run, I'm
certainly open to suggestions.
allegro$ /usr/bin/sudo smartctl --health /dev/sdb1
smartctl 6.4 2014-10-07 r4002 [x86_64-linux-3.16.0-4-amd64] (local build)

I thought those were a direct consequence of the disconnect, though I
don't know what the kernel was trying to write out. I don't think I was
actively using the Iomega drive when I plugged in the thumb drive.
