Hi all, how you doing? I'm alright except for this 'puter problem I'm having that I'll gladly explain to you. I run 4 Hard Drives in my computer. Two of them are regular IDE, and the other two are Sata. I'm using a 430W PSU made by Antec, so based on my knowledge, power shouldn't be a concern. However, my back up IDE drive that shares the same power wire as my OS IDE drive is no longer recognized by my system. While I was messing around trying to trouble shoot, i decided to see what would happen if I switched the power connectors that reside on the same wire, and for some reason, the OS drive didn't boot. I thought to myself, maybe it's not recieving any power? So, to make sure that one of the connectors wasn't working, I decided to unplug the Sata power connectors and try using the power connectors I was using for the IDE drives. Booted the system, and guess what, both Sata drives were recognized, and I concluded to myself, that the Power Supply's connectors weren't the problem. So here I'm thinking, ok, maybe something is wrong with my back up hard drive. Then I thought, hey why try putting my back up drive into my external encloser to see if the drive will work connecting it via USB. Opened up my External Enclosure, took out the hard drive that was in it, and put in the questionable one. Plugged it into USB, and hey look at that, the drive works.... then i thought, lets try transferring data to and from the drive and yup it worked. Now i'm thinking, Ok this hard drive must be making fun of me or something. Took it out of the external enclosure, and put it back into my system. Hooked everything up, and again, It wasn't recognized. I was just about to hit the "Submit New Thread" button when I had a last minute thought. Why not try switching the IDE data cable? So I found a spare IDE cable that i'm pretty sure I've never even used before, so it's pretty much brand new. After about 10 or 15 minutes of messing around with that Windows wouldn't even boot, and I was also getting a wierd message I'd never seem before about how there was something wrong with the BIOS or something, didn't write it down though. Then when I put the original IDE data cable back, everything went back to the way it was before, and here I am ready to click the "Post" button. I'm stumped, WTF is going on?
