[Preston] RE: Strange HDD / IDE problems

[Placard .]

I'm no where near experienced in the field of hardware diagnosis, though I 
did have similiar issues. Turns out the DMA IDE Connector is at fault, and 
I'm pretty happy to blame it for bad sectors.
I hooked the hard drive up with the CDROM, You'll need to switch the hd to 
master if it's not already done.

I'd just like to say that I don't know if it will bring the true issue to 
light, it will help narrow down the possible sources though.
Sorry I couldn't be of any great help :/
