Er.51 can usually be resolved by unplugging it and back in again. Quicker the better it worked for me in the past. The Er.63 I am not familiar with. Just make sure the cables are well seated and if you have an extra PATA cable swap it out and retry.
Firmware changes may have rendered my advice useless but it is worth a try.
