1. 80 uses cable select and is ata166

2. 40 is master slave and ata66 ,100 and 133 I thought you needed to use the 80 wire IDE cable in order to take full advantage of the ATA66/100/133 data burst rates?

I would have to look that up, but I don't think the 80 would have any real advantage with the slower drives.
it mainally to reduce the errors caused from crosstalk at the higher speeds

40 tops out at ATA33. 80 is required for ATA66 and higher. There is no ATA166.

I knew I should have looked it up first.

I have it somewhere in the tips and tricks section... I dismantled a cable and it's not quite as simple as 40 data wires going straight thru and 40 ground wires... there is a bit more method to the madness.
