to try and troubleshoot disappearing drives when the molex connector is switched is done best by a swap.
Recently decided to shoot for a RAID array with two WD800JB hard drives, but I've been having problems ever since. Now, I just want to get the computer back up and running.
Here's the conundrum...as you can see below, I have a 420W PSU, which may or may not be a POS, up until I replaced my second hardrive with a WD800JB instead of a WD800BB to setup a RAID array, everything worked fine.
Now, when everything is properly jumpered, to the best of my knowledge, and forgetting about the RAID attempt, as I've abandoned it, I have two main power cables that can supply two devices and an a: drive (pardon my non-technical jargon). I have the HDs and the a: drive on one power cable (let's call it A), and the dvdrom on another (B). Under this setup, HDs show up fine in the BIOS with correct Master/Slave designations, but the DVDRom (jumpered as Master) does not at all, and its power light does not come on. If I switch the power cords A and B, so that the HDs and a: are on B and the DVDRom is on A, then the HDs do not show up at all in the BIOS, but the DVDRom does and its power light is on.
The only other problem that makes me hesitate to get a new PSU is that I can hook the bad power cord (B) up to the side fan and aux fan, and they both run fine. So there is some juice flowing through the B.
Any suggestions would be appreciated.
