Secondary IDE channel @ Ultra DMA 4?

I’m used to seeing my secondary IDE channels running at Ultra DMA Mode 2 and now all of a sudden they are showing Ultra DMA Mode 4…what gives? (The primary is still UDMA 5)
I’m not complaining of course, but could it have something to do with the fact that I swapped the ribbon 80 lead cables for those illustrated below?

40 Ribbon cables have a max transfer rate of UDMA 2, if your devices are UDMA 4 then using 80 Wire cables will allow them to run at their max speed, if the old cable was also 80 wire then it’s possible that it was damaged.

Thanks, the old cables were 80 wire and I had already replaced them once…well it seems that the new type are working just fine!
