Okay, understood what you mean.
Your bios did not detect both drives and the first drive it detected
was put into the boot sequence.
sorry, but I think that you didn't understand: my BIOS perfectly
detects all
existing drives, as
1/ they are all listed in the BIOS "general" and "hard disc" menus
2/ I was able to put the good one in the boot sequence.
3/ I imagine that if a disc is not detected by the BIOS, it's
difficult
to use it in the OS, after the boot.
You also said that the "disc numbering is not consistent with each
reboot"
This is not true for internal discs.So, the use of UUID in fstab is
mandatory for external drives, but not for internal.
best regards,
Just one reference...
https://help.ubuntu.com/community/UsingUUID
First paragraph reads..
" Linux now prefers to use UUID (Universally Unique Identifier), LABEL, or
symlinks to identify media storage devices on a system. Directly using
/dev/hd*# or /dev/sd*# is no longer preferred since these device
assignments can change between system boots:"
I had experienced in the past my grub-legacy keeps pointing to the wrong
drive. Found out it was the bios. So, in your case, what detects as sda
would be first in the sequence. One more link to illustrate.

But glad to know your bios detects all drives. Your message just put one
drive besides the rom. Phew. That would be really bad.
Oh, a link on ide and sata. Don't know if you have the mix.

Cheers. Hope the above helps.
