50C is within the drive's stated operation range (5 degrees below its maximum); have you felt how hot they get when in real laptops, where they are crammed in with no space for air circulation or cooling?

Connectors/cable could be an issue, though. The cable used in the empegs (and the replacement cables sent out) don't actually have deep enough holes for the length of pins on the drive/main board (so don't push them on too hard); however, the ones used in later rio-cars which *do* have the right depth connectors are so awfully crimped that they have a high failure rate.
