This isn't really very on-topic, but I though should add this quick follow-up.
I'm not sure there was actually anything wrong with the Kingston card (16Gb, maybe 2 years old) I almost threw away. I put it aside and started working with a new Sandisk card, also 16Gb. After a little while, copying stuff to and fro, booting the nanopi, changing something etc - sudenyl it also developed some I/O problem. Odd messages in the kernel buffer, and unable to mount, then unable to even fsck. Partition table cannot be read ....
This all happened with my Lenovo laptop. I began to have this gnawing doubt, and thought I would try an older Toshiba laptop. Hmm, same problem - then it occurred to me I had been in the very same situation maybe a year back.
Solution - put the SD card in my Nikon camera (immediately complains the card needs formatting), format it - et voila!, no problem any more. Did the samne with the Kingston card, also works now.
The difference between the two laptops - in the Lenovo the SD card is available as /dev/mmcblk0, in the Toshiba as /dev/sdb. (via USB).
The difference in behaviour between the two interfaces is bad enough, but what is really weird is that it takes a 3rd device to "reset" the card.
It would be interesting to find out the formatting details as done on the laptops and the camera. I think that would be "on topic" for us, if we learn out how to do it "properly".
Sector/block size perhaps? Filesystem?
may be simply better hardware. I could use card on my EOS5DMKIII at a speed I never could have in my laptop. hardware/driver combination have to be very good in photo camera (specially for video) jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
