Overview
The purpose of this article is to create a disk that can be read / written to by all major operating systems (i.e., macOS, Windows and Linux). A removable USB storage device containing SSD SATA or NVMe media formatted with an exFAT partition can be used to accomplish this. At the time of this writing, January 02, 2020, a removable USB-C drive containing a CORSAIR FORCE Series MP500 120GB NVMe storage device will be demonstrated.
The USB drive is attached to an NST system as device: "/dev/sdc". The parted disk utility will be used to create the GUID Partition Table (GPT) disk label, the EFI System Partition and the exFAT partition.
Zero Out Previous Disk Label - Optional
This optional step will zero out any previous disk label. We will use the dcfldd utility. The first 1GB of the disk will be zeroed out:
[root@shopper2 ~]# dcfldd if=/dev/zero of=/dev/sdc statusinterval=64 bs=1M count=1k; 1024 blocks (1024Mb) written. 1024+0 records in 1024+0 records out [root@shopper2 ~]#
