Hi, I already tried to make a clone of Neo's microsd as a .dmg image, for backup purposes or testing. Now the same commands give me an error: sudo dd if=/dev/disk3 of=~/desktop/neo.dmg Password: dd: /dev/disk3: Device not configured 1546280+0 records in 1546280+0 records out 791695360 bytes transferred in 454.510447 secs (1741864 bytes/sec) After some minutes, the dd command gives the error "device not configures", and the produced .dmg file is only 790 MB (the other backups I did resulted in GBs dimensions). Any suggestions? I don't want to reuse those backups and to start from there because they are old and I started with a new fresh installation in the meanwhile.
