Just in case you are not aware of this, there is a huge market in fake and substandard SD cards, often with the firmware modified to fraudulently claim a larger capacity than the chips actually present. That said, I don't think that they often fail into a read only mode. The only time that I encountered that problem, the supplier replaced the card. sdtool (https://github.com/BertoldVdb/sdtool) may be useful if you don't know about it. I always check incoming cards with f3 (http://oss.digirati.com.br/f3/) which should detect fraudulent cards. Of course it uses up one write/erase cycle, but that can't be helped. So do you know that you have a genuine card purcahsed from a reliable source? Again, apologies if this is all old news. ael _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
