Greetings!

Hm... You might also want to check for a dry solder joint on the IDE header. It is unusual that a recrimp would become loose again. At least, yours would be the first case of it I have heard of. You can contact support for the cable (they are technically standard laptop IDE connectors, but the bends and lengths are custom), but the quick fix (if you only have one hard drive) would be to move the hard drive to the other physical connector and see if that helps.
