Go to Control PanelOpen up the System and Security groupingOpen Administrative ToolsOpen Computer ManagementUnder Storage, click on Disk ManagementUnder the drives under disk management, you should see all of your drives listed. The one you can't find in Windows is likely formatted using a file system that Windows 7 doesn't like (like FAT or HFS+). Right-clicking on that drive should give you the option to format it using NTFS or FAT32 (NTFS is preferred). Format, restart, and Windows should now automatically assign it a drive letter.
I have 1.5 TB of stuff stored on the disc so that is not really an option. Besides, it's already formated using NTFS.
Can you maybe post a screen shot of the "Disk Management" window?hint: Alt+Print Screen takes a screen shot of the selected window and not the whole screenMaybe the drive just needs to be mapped and not formatted.
We need the pictures from the Administrative Tools -> Computer Management screen, not Device Manager. Device Manager doesn't tell us anything relevant about the formatting of the drive.
HAHAHA! Never mind, I fixed it myself
bet that was a relief
The first problem was that I was looking at the wrong place, I was trying to solve it in Device Manager when I was really looking for Computer Management. I instantly recognized the problem, it wasn't assigned a disc letter.
