Today I tried to clone my laptop’s harddrive to a new drive (thanks to Lenovo for sending me a replacement since the old drive was showing signs of breaking down). At first I tried dd, but that failed at around 90%, either because the old disk is indeed failing or because something fishy with the USB connection or enclosure in which I put the new disk. So I started gparted to check which partitions were copied OK and which weren’t. It turns out that all partitions were fine, except for my (encrypted) swap partition. gparted didn’t even recognise the partition type (on the original drive!). So after I replaced the harddrive I wanted to recreate the encrypted swap partition. It turn’s out to be easy if you follow the steps outlined in this blog post from Puny Geek. Thanks Puny Geek!
