You could go about this in a number of different ways. |
| 20 |
|
| 21 |
dd command will take forever, as it is copying every bit and byte from one |
| 22 |
disk to the next, whether it contains data or not. |
| 23 |
|
| 24 |
I prefer to use a clonezilla liveUSB to copy a disk or selected partitions |
| 25 |
between disks, which will take significantly less time as only blocks with |
| 26 |
data get copied over. |
| 27 |
|
| 28 |
You can increase the partition size after you finish copying it onto the new |
| 29 |
disk and then the filesystem size within it. Gparted can run both steps in a |
| 30 |
single stroke. |
| 31 |
|
| 32 |
If you prefer a more manual and tedious way, you can create a partition as |
| 33 |
large as you need it to be on the new disk, format it with a filesystem of |
| 34 |
choice, then use rsync or tar to copy over the files you want and --exclude |
| 35 |
anything you don't want copied over. |
