While trying to run rsync to update backup files on an old external USB
drive, I received the following errors in the kernel log. Interestingly,
the device is disconnected and later reconnects. It's connected via a
powered USB hub.
I suspect the drive is probably a decade old at this point, but it
hasn't been used a lot (just occasionally for backup purposes).
On the drive is a LUKS encrypted volume, on top of which is a BTRFS file
system.
There has not been any data loss, in the sense that the SSD on the host
system still contains working versions of all the files backed up. The
main question is whether this looks like a drive hardware failure, as I
suspect it does. I've included the logs of the disconnection and
reconnection events that also contain the hardware details. My suspicion
is that it's time for a new backup drive. Comments welcome.
