Again two hard drives IDE and SATA. Now SATA is /dev/sdf (hd5,2) and

GRUB counts hard drives, doesn't care where they're attached, it only
counts the hard drives, skipping other drives.
e.g.
Port Connected Older Linux Grub

IDE1 primary HDD /dev/hda hd0
IDE1 secondary nothing /dev/hdb
IDE2 primary CD-ROM /dev/hdc
IDE2 secondary Zip drive /dev/hdd
IDE3 primary HDD /dev/hde hd1
IDE3 secondary HDD /dev/hdf hd2
I've picked on the older Linux scheme of absolutely referencing drives,
being something that many of us are very familiar with, and to show what
consistency versus inconsistency does for getting predictable results.
I haven't worked out how the new /dev/sdx scheme will work, but I
suspect you'd see this sort of thing:
Port Connected Older Linux
---------------------------------------
IDE1 primary HDD /dev/sda
IDE1 secondary nothing
IDE2 primary CD-ROM /dev/sdb
IDE2 secondary Zip drive /dev/sdc
IDE3 primary HDD /dev/sdd
IDE3 secondary HDD /dev/sde
And, if you plugged in an external USB drive, and *if* your BIOS will
use USB first when there's something on it, you could expect them all to
shift to higher letters, with your USB drive being /dev/sda.
That does not sound like progress. But it sounds different and would
mean you cannot live without labels and the whole thing will be a mess
to understand.
