I've spent days reading this forum and others trying to figure this out. Any ideas would be appreciated. My setup is listed in my signiture. I started with an 80gb WD drive, and had to "rig" the network adapter to fit the drive. Got that accomplished and booted HD Loader. HD Loader tells me that there is no drive present so I find a copy a HD Advance and get the same results. Yes the drive is set to Master, and yes I've confirmed the drive works. There was only 1 time that HD Loader actually recognized the drive and attempted to format it, but hours later I gave up and assumed it wasn't going to happen. So I check around and there is mixed results about the compatibility of that drive. I head to the store and picked up a Maxtor 160GB drive now. ( model # 6Y160P0 ) Swap drives, boot up HD Loader with the Maxtor and I get the same exact results. This drive when I searched has 100% compatibility with every version PS2 listed, so I am confused as to what the problem is here. HD Loader and HD Advance both tell me that no drive is present. I've checked the new drive in my PC, and it is fine, and the jumper is set to Master. I will however try it set to Cable Select and see where that gets me, if anywhere, as I've read that some people have had their drives recognized when using the "wrong" jumper. Any advice? Ideas?
