How to mount an external USB ?

[adrian9af]

I'm looking at 3TB USB drives from Western Digital, Seagate and Toshiba. It's for backing up a Raid1 configuration. These products all advertise that they are compatible with Windows or Mac OS. What are the steps to re-format and mount for Centos ?

Does Linux see the device at all? If you run "fdisk -l" does it show up?

With a 3T drive you need to use parted, not fdisk.
