/var/log/messages has indicated a slew of XFS problems on an external
USB hard drive (see attachment). These look pretty fatal. Anybody
think the file system is recoverable?
Also, palimpsest is reporting (graphically) that my external hard drive is
about to die. Can I save it's report to a text file???

You'll have to try to recover it, to see if it is possible: xfs is vulnerable
to power interruptions, so a faulty USB cable can cause corruption. I haven't
had a corrupted xfs system for years now, so I put initial experiences down to
early (buggy) versions of the drivers. In my case, I was not able to recover
and I had to reformat and start again. After a couple of early mortality
cases the fs in question carried on for 4 years without a single problem.
Try xfs_check and xfs_repair with the drive unmounted, but first use
xfs_dump/restore or dd to make a back up just in case.

Sorry, can't help with that because I'm not familiar with the application.
You could use sys-apps/smartmontools if you want a console application that
you can copy and paste from.

I had exactly this problem with a USB HDD formatted with xfs. The USB
cable that it came with was rubbish... the drive would disconnect &
reconnect on its own for no apparent reason, and corruption happened
of course. I replaced it with another cable and it worked fine after
that.
A few months later the power supply started to fail, it would
occasionally not provide enough power and the drive would go offline
or start beeping/clicking. At first I thought the disk was bad
(clicking is never good) but it was actually the sound of the drive
trying to spin up and failing. Eventually the power brick couldn't
even spin up the drive at all. I replaced the power supply and now the
drive works fine again, for now...
