the above happened some time ago on a previous PC.

Well then, pull the cable from the SATA 1 connector. If
the PC boots, or not, you now will know which physical
drive is which. Another way to resolve this is to use a utility
which reads the SMART info from the drives to find the
serial numbers, although that will require pulling the drives
to read the SN's, unless you can read the top drive's SN.

I have just used Hitachi's Drive Fitness Test software which tells me
that I have

00 ATA Secondary Master HDT etc and the serial number is R3CA etc

01 ATA Secondary Slave HDT etc and the serial number is R3C9 etc

so I now have 2 different serial numbers and can check these against
the physical hard disks.

But! How do I move from this to knowing which is the C: drive without
trail and error booting?

So far I don't seem to have any info from XP Pro to connect the
logical C: drive with SATA 0 or SATA 1 socket....or do I?!

Cheers

You've already determined by using Disk Management that
Drive 0 is the C: drive.

It could. Open device manager, find the disk drives and open them, see
if the "Location" field gives you any clues. If the "C" drive is the
lower number then SATA 0 should be the "C" drive.

You may not see locations of "0" and "1", spending on how the
motherboard is designed, I've got an older mobo here where SATA drives
start at 4, IDE drives take 0 through 3, despite being labeled as 0
through 3 on the motherboard.
