I have a western digital caviar 21600 drive that my bios detects if it is in the slave postion only....If I change the jumper to master and move it to the end connector on the cable and try to boot that machine no dice it freezes at the auto detect drives part...I can put another hard drive on the master and put the WD back to slave boot the machine into windows and use the drive as a slave but I want to use it as a Master....please offer any suggestions on this....I am at a loss
