When you format a hard drive or delete a partition, you're usually only deleting the file system, making the data invisible but not gone. A file recovery program or special hardware can easily recover the information.
Saxo is right - the only way to make sure your data is inaccessible is to physically destroy the disk. Remove it and break it - very satisfying!
There really is no other way of making it safe - I have a friend who (legally - it's for his work) has all the kit to recover data from disks - it's amazing what he can recover data from. Don't risk it - break it.
To put it into perspective - even if a hard disk is physically broken into (a few) fragments, certain agencies/institutions have the technology to recover data from those fragments. To defeat this, a disk would need to be reduced to extremely small fragments.
There are several software programs available which will wipe, format and then overwrite with zeroes every part of the disk, which would make it extremely difficult to all but the most determined (and well-equipped) to recover any data.
But as said - breaking it into several pieces should do the trick...

Never thought it would be this hard to get rid of them. Still its got to be done. Don't want anyone getting hold of my millions do I. Thanks for all your suggestions. Geoff
Salt water and magnets won't work I'm afraid. The hard drive is hermetically sealed so water will only damage the electronics, not the discs inside where your data is stored.
Magnets would work if you had one sufficiently powerful, but such magnets are not generally available to the public, with good reason.
To make data recovery difficult/impossible, you need to damage the discs inside. Drilling holes right through the disc is one of the best suggestions so far.
Take the HDD's out smash with hammer put in the metal recycling or bin, put the laptops on Freecycle the remaining parts could be useful to someone, job done. No one going to try to reassemble a damaged HDD even if they knew it was in your bin. No HDD no data to be used or copied.
I'm not sure that fire will destroy it. We were on a computing course a couple of years ago and the tutor mentioned a fire which had destroyed a school's or college's computer room, but the hard drives were salvaged from the melted equipment and the data was recovered.
There is always the possibility of donating it to a charity which recycles computers after confidentially wiping any data on the drives. OK, some heavy techy bod might be able to get at some snippets of info and reassemble, but if they are going to those lengths, it would just be easier fot them to rummage around the bins at the back of your local high street bank.

I didn't do it !! Nobody saw me do it !! You can't prove anything !!
In work with me we wipe Data off hard drives everyday, we use a program called BLANCO (perhaps you could try and find a computer recyclers near you who can do this for a small fee) We wipe the drive with our software and it is wiped 3 times to make absolutely sure it is completely clean of any data, If the hard drive does not work we take it out of the laptop which is usually only a few screws and punch a hole through it, with the laptop drives they are very brittle so if you were to drill a hole through the drive (not the center but between the center and the edge of the drive) you can shake it rattling, this is now destroyed and cannot be recovered in any way.
Try and get in contact with this company, they do the same as I do but they are in Kent, they will charge you for doing this but they should guarantee no data can be retrieved, also they could recycle your laptop or parts off it.
