Hard Drive Setup

[shodan]

Does it matter whether hard drives are primary or not?

I have the Asus P5W DH Deluxe and I've got 2 sata hard drives. The hd with the OS is connected to the port 'sata-1' and is listed in the bios as the third master, whilst my IDE DVD writer (being the only IDE drive) is listed as the primary master. Does this matter? I'm having problems doing anything in XP as descibed here

Let me know if you think these are related. Thanks

Edit: The second sata HD is connected to the Jmicron controller and doesn't show up in the bios. It works fine in XP though.

Ok Thanks. Running memtest right now.

I'm using an Enermax Liberty 620W and the problems aren't random or intermittent so I'll presume it isn't that.
