Mine's by Samsung:

It's clearly visible to the kernel, and smartd finds it too if I tell it 
what to look for.

I don't want to start unplugging it unless I have to, as it's in a PCI slot 
and I'd probably make things worse. And it is only 18 months old, as I said.

A week or two ago I was investigating some other weirdnesses and at one 
point I zeroed out the first partition: the unformatted one containing the 
UEFI data. It took longer than I expected, having only 2MB to fill. I wonder 
if it strayed outside the partition...
