Del XPS 15 l502x - fitting 2nd HDD to optical drive bay.

I have a Dell XPS 15 l502x and about a year ago I replaced the Drive 'C' with a SSD, took out the optical dirive and fitted a HDD caddy, to which I fitted a 750GB hard drive as 'D'. Everything has worked fine and the only problem has been that Drive 'D' now needs to be a larger capacity, so I duly bought a 2TB drive to replace the 750GB drive in the caddy.

Replacement went well, the new drive being duly initialised and then existing data transferred over.

However, when I now boot the laptop up one of a few different problems occur:-

• The laptop doesn't recognise the 'D' drive as being there, i.e. it doesn't show it at all, or
• The 'D' drive shows, but clicking on it shows nothing on it, or
• The 'D' drive shows and the folders on the drive show but the folders show as being 'Empty'.

The new 2TB drive seems to be working fine and is 100% when fitted into an external drive caddy and plugged into a USB port. I have tried two different drive caddies and the problems exist with both.

So I guess my question is, can the Dell XPS 15 l502x cope with a 2TB HDD fitted to the optical drive bay?

Many thanks for any replies :)
