Many years of digital photography have rather filled my hard drives. (I probably don't cull my images sufficiently). So I decided to replace one of the 2TB hard drives in my computer with a 6TB drive. The easy bit was physically replacing the drive inside the box. Getting it working was very easy as well (I had feared that I might have difficulty getting Windows to recognise the high capacity.) Now comes the slow part - transferring all the data from the old drive to the new one.
I started it early this afternoon. The current estimate is that it should be ready by breakfast tomorrow.
