New drive isn’t visible

I recently fitted a second internal hard drive to my desktop PC. I’ve double-checked the physical connections and verified it’s visible in the configuration utility that appears before you boot Windows, but there’s no sign of it in Windows at all. What am I missing? A driver? [ LEONARD GREEN ]

Matt Hanson replies: It sounds like the drive hasn’t yet been initialised, which you can do in Windows. Right-click the Start button and choose Disk Management, which will list all the drives attached to your PC. You should see your new drive is visible here, but it’ll be marked as Unallocated. Right-click this space and choose New Simple Volume. Follow the wizard through the steps to set it up — the default choices will create a single NTFS-formatted hard drive complete with drive letter, ready for you to use.
