Read-only file system on /dev/sdi?? This is very out of the usual: This seems to indicate that your "/dev" filesystem is read-only, and "dd" cannot create "/dev/sdi" ... What does: ls -l /dev/sdi report? I suspect it will say the file does not exist. If /dev/sdi does not exist, dd will attempt to create it. As a normal file. Which is probably not what you want... Similarly, can /dev actually be written to? The output of a command like this would be instructive: touch /dev/somefile-which-doesnt-exist > > Is there a way to force it to mount read-write ?
