I've got an iPod with a broken Hard Drive. Copying files to it gives me an error that coyping to the hard drive failed.
I've got a computer with a failing keyboard. Several keycaps have simply stopped working, and the D key is completely destroyed in a way that makes it practically unusable. (Removing the keycap, and the nipple, and pressing directly on the pad does 'work', in a way.
Then there's the issue with the Powerbook hard drive: when there's less than about 5GB of space filled, I get kernel errors when trying to read from the files (randomly). The hardware there is probably horked, but of course, proving that it's not my fault (since this machine has been beat up pretty badly) is hard.
