It means that the USB dongle that you've plugged the SD card into doesn't
think there's an SD card there. This could be from a variety of reasons:
1. The SD card isn't well seated.
2. The SD card isn't completely compatible with the dongle or the dongle
is defective.
3. The dongle can't make the SD card produce the sector requested
Most likely #3 is the problem, but if the data is super important
I'd try a different dongle. #1 is easy to re-try. I've had dongles go
bad on me as well as SD cards.If this is the only sector it complains
about, then you might be able to read the rest of the card, though
that's a failure mode that's I've never seen with SD cards,
just actual SSDs, HDDs and CF cards.
But yea, if reseating a couple of times doesn't resolve the issue,
I'd say there's about 90% chance it is the card, 10% chance it's
the dongle that's bad.
