- Some microSD-to-SD adapters can lead to serious problems reading your microSD card. In such a case a normal SD card will be detected instantly but the adapter with the microSD card will fail to be recognized. The syslog (take a look with
$ tail -f /var/log/syslogwhile inserting the card) will only show this line:
mmc0: error -110 whilst initialising SD card. This issue is caused by a bad electrical connection, pulling the adapter out a little will solve this in most cases. Permanent fix: use a better adapter.
