If you haven't ordered those jumpers yet, I have about 23 of them (ordered 25, used 2 I think) so I can let you have some if you want, I'll never have that many laptop hard drives!
The Farnell online ordering system screwed up when I ordered them, I ordered 1 pack of 25 and got 25 packs... they were going to charge me over £100, which I think was more than the cost of one of the 30GB drives I was installing!
They took the surplus back, with no arguments... even arranged a courier to collect them.
