I installed another hard drive with XP on it as a secondary hard drive my master hard drive has ME I wanted to just install the one with XP but it wouldn't work so I hooked them both together any tips on how to retrieve info off the one with xp or make the one with xp work so I will have XP instead of ME.Thanks;)

You got right jumper settings and are they in correct slave/master positions etc. Might be a conflict because of the two different OS's, shouldn't matter unless you want to dual boot etc.
