On a similar subject:

I had to replace the hdd cable on one of my empegs. I've got a 44 pin cable, but the blank where a pinhole (on the motherboard's end) doesn't fit, so I don't wish to drill into it if I don't have to. If I
drilled into it, would the connection matter? Does the extra pin on
the MoBo actually matter?

Also: I'm having the same hdd not detected issue. If the soldering is necessary, is it difficult or self-evident?

Thanks
