Just to confirm - no lvm/mdadm/etc involved?  Not that they should be
misbehaving but those are things to check.

(Just for those following along, that's pretty close to an upstream
LTS kernel - currently 6.6.62 if updated).

Well, memory was the first thing I was thinking.

Do you get panics or freezes or anything like that, or do you just
happen to notice it when something goes missing while the system is
up?

Do you notice anything in dmesg?  That should end up in your log.

How about smartctl - does it show anything?  I think that will show
both disk and interface issues.

Is this a laptop you frequently start/stop, or does this just stay turned on?

You're mostly doing the right things, I'd be very interested in the
output of smartctl -a though.  Also, try grepping logs for /dev/sda or
whatever it typically shows up as.  If there is some kind of interface
issue dmesg tends to be pretty loud about it.
