The discussion of mechanisms for protecting SD cards were all about
write-protecting them. Read-protecting them would be a really cool
feature - hey, I have a 5TB card here for you, just $5, it's
read-protected... Cash only please...

If any card can't be read, try a different reader and check the
contacts. If that doesn't help, you have a hardware fault.
SD cards are a commodity item, that happens all the time. Personally I
rate Sandisk, Lexar at the top of reliability (and price and speed),
Adata not that far from the bottom. I have come across a friend's
Sandisk Extreme uSD card coming dead out of her phone with all the
holiday photos on it...

I'm curious to try those cards myself on a Linux machine, and see if the
tool Helmut mentioned makes any difference. You're welcome to visit, or
at the Feb meeting (it's Linuxconf next Monday).
