I take it, then that your "boot order" in the BIOS is set to boot from
the first IDE drive, and you don't change that setting to boot from
another drive, you use a GRUB menu for choosing the boot drive.

Your second drive is an external one?  Or you're using PATA and SATA
drives on different host adaptors?

If you have other drives, such as CD or DVD, or memory card readers
(even if they don't have a card inserted), that could account for some
of the gap between sda to sdf.

The second grub has a "#boot=/dev/sdb" comment, and that may have got
the more logical second device (sdb) name because the hardware was
assessed differently by the install disc, than after the system is
running.
