This is most likely correct. I re-installed the OS on a

UGH! Yes, they can. It SHOULD cause a device parity error,
but I guess some of their coverage is less than 100%
perfect. But, there are LOTS of reports of bad SD cards,
cards with dramatically less capacity than stated on the
outside, early failure after just a few hundred writes, lots
of reports of total corruption when power is dropped without
warning, etc. Just read the horror stories online.
