I purchased two 250GB WD Scorpio Blue hard drives (one per MK2a player of mine) and I downloaded the 3 latest big-disk-builder images with LBA48 support (v3, v3_alt & v6). I tried running each one with the Upgrade Wizard and I tried both hard drives, but every time I encounter the same problem: Error "Bad pump response" occurred during stage 0x25. I plugged the hard drive into the end cable position (with the red band on the side of the #1 pin) and one attempt I even added a jumper to bridge the end pins which I believe is the slave/master jumper setting.

Can someone (perhaps named Mark Lord) fix this? Help...
