I have a trial version of Photoshop on a fairly basic computer (no other
apps) and I thought 'Well I'd actually like another 30 days please'. So I
reinstall the operating system... But Photoshop is cleverer than me and it
knows that I've already had my time.

How does it do this (I reformatted the hard drive) and can I get another
trial period?

HDDs have spare tracks that are used if bad ones are found.  The locations
of the bad/spare tracks is kept on the drive. One possibility is that PS is
using one of the unallocated spare tracks.  It may also be using an
otherwise inaccessible track.  If that's the case, no amount of
re-partitioning and re-formatting is going to make a difference.  You'll
have to write a low-level disk access program that reads the tracks on the
disk.
