Seeing that these are run-of-the-mill 40pin IDE cables, try cutting line 1 (the red line). It used to fix problems with the old seagate drives not being recognised but that was when cold booting the machine (the drive was too slow at spin-up).
Who knows, maybe it works.
Also, I have had many WD drives not functioning properly until I removed all jumpers for Master/Slave. Normally there is a jumper you need to set at Master/Slave or Cable Select, I had to remove the jumper completely on my WD drives.
