The amazing thing is that after lots work, I managed to re-construct the home partition enough to save most of my data changed since the previous backup. As I'd over-written the partition table, this involved grepping the block device for "ReIsEr34" so I could find the block a certain number of sectors in from the beginning of the partition (16, I think, but I don't remember), then useing this information to re-build the partition table.

It's actually not that hard, provided you know aproximately how big your partitions were, and you've not changed the virtual layout of the drive (which I did). Most hard drives come in a default virtual configuration of the number of cylenders, heads, and sectors that is not the same as the physical layout. Theoretically, you might be able to improve the accuracy of the scheduler by changing this to the physical layout.
Don't.
If you lose the partition table it will default back to the virtual layout, and

Several people have quoted this, but I don't buy it.

1) Heat the drive above room temperature. I'm not saying boil it; I put one of those chemical hand-warmers on mine and left it in a box for a while. This should heat it to around 40C.
2) Connect it to your computer, but leave the drive itself out on a desk. May require some monkeying with your case to let it run while open.
3) Turn the computer on. If the drive still clicks when it tries to spin up, tap it on the corner (in a way that would spin the drive if you hit it harder). The idea is to provide some torque to break the static friction of the lubricant and get it spun up.

Why you stick a hard drive in the freezer.... (Score:4, Informative)
This really isn't a problem on modern drives, but in the past it would happen. Something that would work to unstick the drive head was to stick the drive into the freezer. This would (presumably by a slight contraction of the platters) allow the drive to spin up. Once the drive was warmed up and spinning, you could then proceed to back up as much of the data as possible before the drive failed.
Now, it's highly unlikely that the person mentioned in the FA had a drive that was suffering from stiction. Modern drives rarely have this problem.
