We know that A1200/A600 has an ATA-0 interface which supports only upto PIO-2 commands.

It is possible that the IDE controller in the SX-1 is slightly different? After all it is unique to the SX1 isn't it?

Perhaps the SX1 interface supports higher levels?

I could be wrong. Looking at the photos there is no ROM on the SX1 board. Which hints towards it not being a custom IDE interface but a remake of the A600/A1200 Gayle registers.

Which in that case... it can only be signal strength and timing which are different.
