So I have 2 hd's one is smaller and holds my windows install. the other is much larger and holds all my files. Up until recently they have been working fine. I tried installing the second hd on a different computer to see if I could get some info off of it and it wouldnt work. So I tried putting it back on the first computer. Now it wont turn on if the second hd is connected. I have tried everything I can think of. I have even gone so far as to just connecting the power connector to see if that would work. Whenever I connect the second hd the computer simply dosent turn on and i have to unplug the power cord and wait for the green light on the mobo to turn off before I can try again. Any help?
