I recall IDE docks to be iffy at high IDE speeds. I do not know if your PC can limit IDE MODEs to slower rates but we had to do this to get docks to work.
Did you test this dock?
Need a HDD docking station for a 1993 Western Digital Caviar 2420 HDD (425.3 MB). Bought a StarTech UNIDOCKU33 but was told afterward that it won't work with a HDD less than 1GB.
