Was going through my usual process of writing a Raspbian image to a microSD card using
sudo dd bs=1m if=/my_pi-zero.img of=/dev/rdisk3 conv=sync on my mac and I received the following message
dd: /dev/rdisk3: Device not configured 4451+0 records in 4450+0 records out 4666163200 bytes transferred in 582.264839 secs (8013816 bytes/sec) Copied /Users/Matthew/Desktop/Photo-G/Pi-Zero.img to disk3
dd: /dev/rdisk3: Device not configured is not part of that message.
However, when I plug the SD card into my Pi everything seems to be normal, could there be something wrong under the hood or should I just ignore it?
EDIT: It's also worth noting that the image file is 7.96gb so the transfer is being cut off partway through. The microSD card is 8gb and I haven't previously had a problem like this with this script.
