I just got a 1 TB WD hard drive to go along with my 500gb version. I installed it in my computer fine and when I booted it I went to the Bios and it showed up and when I got into windows it installed the device software a it does but it dosen't come up in my computer.
What should I do and thanks for any help.
A brand new internal hard drive has to be partitioned and formatted before Windows can assign a drive letter to it and write data to it. You can do that in Disk Management where the drive should be shown as "Unallocated Space".
Control Panel > Admin Tools > Computer Management > Disk Management
Find the drive in the bottom-right panel (unallocated space).
Right click and choose "New Simple Volume".
When that's been created (only takes a few seconds), right-click on it and choose "Format" (takes considerably longer than volume creation).
