No amount of data damage you can do with a broken plug would affect read performance with dd once you connect it up properly. You don't even need ddrescue. If you haven't yet done so, do that now and start again.
If the disk had read errors (average 1MB/s sounds rather like it) then technically you run rescue operations on a copy of a ddrescue copy. If you don't have the space you get only 2 goes (one on the first copy, one on the bad disk). Buy another disk if it's important. You can find out if the disk has surface errors by running the smartctl command of the smartmontools package. Note that if you connect the disk through anything involving USB then you need an adapter which is designed properly, and a rather recent version of smartmontools.
