Hi, I have a Crucial SSD connected externally via a SATA-USB cable. It has one partition spanning the entire capacity of the drive with no data on it (I've already erased it). I will be returning the SSD to where I purchased it from and so would like to return it in as much as possible the same condition as I received it. That means unformatted with no partitions as a bare drive. Thus my question is: How do I remove a partition in OS X? Not format/erase, not resize, but remove entirely, so the drive has no partitions. I am not afraid of Terminal commands. OS X 10.11.4. System as signature. Thanks.
