Since it is not the lock issue, try first diskutil unmountDisk /Volumes/UNTITLED and then try erasing the partition. Sometimes, you can also select the hardware APPLE SD CARD READER, going to partitions, and selecting from current, to 1 partition, formatting and applying. Should delete, and re-add a partition

It does not recognize because you put the < and > signs in. If I were to username I'd do John not <John>. So sudo chown fabrice /dev/disk1

Try executing: sudo chown <username> /dev/disk1, with <username> being your username. You might also try sudo chmod 750 /dev/disk1. These commands set the permissions, as permissions error might be the case, since the Info tab says you can only read
