I keep the cable connected to both the motherboard's sata port and to
the external eSata disk enclosure.
I noticed that the cable indeed needed reseating, but on the other hand,
the external disk had *not* been powered on since last reboot, i.e.
before these "errors or warnings" in dmesg had appeared.

FWIW, after reseating the cable, I powered the external disk on, run a
forced fsck on it, and no errors where reported.
