First time I did it, I faced that scenario too: |
| 21 |
|
| 22 |
/ wasn't big enough and I didn't have enough free space anywhere to put |
| 23 |
a temporary copy. So I juggled everything around in chunks playing the |
| 24 |
disk-partition equivalent of 15-pieces. Took about a day. |

What I *should* have done is bought my first external USB drive then, |
| 27 |
not three years later. |
