Create partitions Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Device does not contain a recognized partition table The device presents a logical sector size that is smaller than the physical sector size. Aligning to a physical sector (or optimal I/O) size boundary is recommended, or performance may be impacted.
