Thank you for a lengthy and helpful reply, Dorothy.

The HDD has now failed to work for nearly 24 hours. Its condition
exacerbates because I now fail to even get that 'slow rotation'. It remains
quiet at the start and then makes some knuckle-like noises.

I will buy a new one later today. Luckily I backed up all my files on August
