Disk 1 which is the original one containing the master boot record and Win Vista boot
Disk 2 which was the next one added and has the Win 7 boot
Disk 0 which was the last one added and only has data at present
My question is why the latest one isn't Disk 2. Is it something in the bios

However when I dismantle everything in a week or so when I replace the motherboard I will check which sata ports they are actually connected to
It would appear - from the bit I do understand - that it doesn't really matter as long as the boot order is set correctly in the bios although I suspect that even if it is wrong it will still finish up booting from the disk with the MBR

Both my disks are bootable; I rely on the BIOS to set the boot order.

This should not affect boot as long as there is only one drive with an MBR: not sure what happens when there is more than one and they change order.
It should not affect Windows drive letter assignment, which is what matters in normal day-to-day running of the OS. I'm not quite sure what Windows does to make the drive letters 'sticky' over reboot, but it seems to work.
The only thing to be careful of is when using programs such as parted that do use drive numbers. Just make absolutely sure that you double-check the current drive order before doing anything that could be damaging. I think most of us who dare use such programs are already pretty paranoid when doing so.

External drive numbering does up to 17 according to Belarc.
What I have noticed is generally after I 'Eject' an external then power it down the next time I power it up it has the same drive letter even if lower drive letters are available due to other drives being off. But sometimes it is allocated a different letter. Never worked out how/why.

makes it easier then so I can always find the stuff I want in the same place (which also means the hyperlinks will point directly at the correct point) without needing to always check what letter was assigned this time...
as to the boot time and the numbering, that literally changes every boot, my drives will swap from 0>29 at random every day (that being the totally number of fixed "drives" in the case although most of them are just card reader slots) not that it matters very often and when it does I always use the disk part command suite

It's usually easy to think of a word which can be descriptive of the drive or contents and then assign the first letter of the word as the drive letter; e.g D:Downloads F:Files G:Games M:Music P:Paging etc.
