I have a hard disk of 320GB attached to a debian machine and a new 2TB drive which will be an upgrade for the smaller drive.

I've just tried to clone the smaller drive to the larger drive using the following command:

sudo dd if=/dev/disk5 of=/dev/disk2 bs=4096 conv=sync,noerror

However this has resulted in the 2TB drive showing as 320GB.

When I run (the sda numbers have changed as I did the clone from my mac and then plugged the drive into the debian machine):

sudo fdisk -u /dev/sda1

I get the following output showing that the 2TB drive has shrunk to the smaller drive size.

Disk /dev/sda1: 298.1 GiB, 320071884800 bytes, 625140400 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x5094580b

How do I expand the drive to show it's full capacity, preferably without having to dd again as it took a very long time?

I've tried:

sudo resize2fs /dev/sda1

But that doesn't do anything. It gives the following output:

The filesystem is already 78142550 (4k) blocks long. Nothing to do!

UPDATE:

If I run:

sudo fdisk -l

I get the following:

Disk /dev/sda: 1.8 TiB, 2000398934016 bytes, 3907029168 sectors
Units: sectors of 1 * 512 = 512 bytes
