It maybe that in my simple approach I have indeed got it wrong and that migration of the software is not just the OS
but the whole HDD
Right.
I'm not really familiar with Partition Master, aside from managing partitions.
For cloning/Imaging operations, I use Macrium Reflect.
But that partition master might do it as well.
But...I've not seen
any application that will migrate 'only the OS'. I've seen a couple that say it will, but I've never seen or read of anyone having success.
Mostly, all or nothing. OS, applications, everything.
A couple of them let you leave out static files like doc/video/music. But other than that...everything on that drive (or partitions) goes.
So...to reiterate:
You have a 500GB drive from an HP laptop, and the drive is showing SMART errors.
And you're trying to clone this to.....what, exactly?
And to put the clone into what, exactly?
