Hi, The drive didn't show up in the bios as far as I could see, this link talks about secure boot. I have since tried an external USB enclosure, and that did recognise the drive and I was able to format it. I tried again to install the drive inside the laptop and it was not recognised as before. So, the drive itself is working, is the socket or laptop faulty, do you know if are there further settings I can try? best regards, Joe
