It's the controller, not the disk that matters. One of the
controllers is SATA, the other's not.

What in particular makes it odd? That manual handling is necessary?
Trying to automatically handle the change in the installer would be
somewhere between fragile and impossible and create other problems.

you'll need to change it back. Good luck!"
If you don't feel like crossing that bridge, you might be able to tell
the bios to run the controller in compatibility mode instead of the
better SATA mode and then you wouldn't need to change anything, but
it'll be slower.
