If the moral of the story is true then everyone would have to spend double on storage because thay would have twice the amount of data (back ups).
There is no way around that. Be prepared to lose anything that isn't backed up. It will
happen some day. In fact, you could do more than 2 copies (I have 1 copy at home, and another "off-site"). But it's not like you have to backup *everything*. I couldn't care less if I lost my Windows install, VMs I can recreate in mere minutes, and stuff like that, due to a dead drive or whatever. As long as my *important* data is backed up (again, things like family photos -- your kids won't get younger again, no chances to re-take those pics, ever)

I would really like to know how to build the serial -> SATA interface to connect to the hard disk.
It's just a very simple circuit that does level shifting on the serial port (to have "proper" rs232 voltages towards the PC, and TTL level signals towards the drive). It's really nothing special at all: it's a TTL level serial port, like found on almost all embedded controllers (the only "hard" part here, is knowing which pin is TXD/RXD, which is still quite easy). A plan old max232 chip or any equivalent will do, but then again, most serial ports these days will work at TTL levels just fine (still gotta invert it though -- a pair of plain old GP transistors works fine or even a ghetto old 74LS14 or 04, and also clamp the voltage not to fry the drive's controller). You could even make a USB version of it using a FTDI series chip (or any of the other common ones like cypress and others). Or then again, you can buy such pre-built devices from dozens of sites (they're actually very common devices).

its very easy to mess up any chance of recovering your drive.
Exactly. The old drive can still be RMA'ed. And removing BSY alone will likely not bring it back to a "functional" state (i.e. in a state where you can recover your data). As the video Fuzzy_3D posted shows, there's quite a bit more to it. A minor screw-up in connections can easily fry the controller or worse (it's simple stuff, but some people shouldn't be near electronics...) And the whole thing still relies on you entering the right commands (which are poorly documented at best) and where any minor mistake may have unfortunate consequences...
Either ways, good luck
