I've just bought a 4TB external HD from Seagate and want to use it as an extension to my laptop (Linux Mint 18). However it's not mounting automatically. Having searched several forums, I can't find a solution to this. I've tried addressing the HD in the terminal, but$ sudo parted -lModel: ATA SAMSUNG MZNLN256 (scsi)Disk /dev/sda: 256GBSector size (logical/physical): 512B/512BPartition Table: msdosDisk Flags: Number  Start   End     Size    Type      File system     Flags 1      1049kB  25,0GB  25,0GB  primary   ext4            boot 2      25,0GB  256GB   231GB   extended 5      25,0GB  246GB   221GB   logical   ext4 6      246GB   256GB   10,1GB  logical   linux-swap(v1)doesn't show the HD.$ lsusbBus 002 Device 004: ID 0bc2:231a Seagate RSS LLCBus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hubBus 001 Device 006: ID 138a:0090 Validity Sensors, Inc.
