I've never had it cause issues. BIOS has always recognised the HDs and
linux, until now, has always been more than happy to work with them.
This is across many different mbs, ide chips and hds.

On this server a lone hdd has been the case for 4 years and has worked
fine.

It is what worked, after a lot of futzing around. Still, this is a
regression (from the pov of someone who just had to futz). Before
whatever change was made things were fine and futz-free.
