Right Click the "My Computer" icon, then click on "manage". This will bring out the Computer management window. Find "Disk Management" and click it.
Check if you can find the missing unformatted 130 GB disk space on the lower right window. If it is there, right click on it and assign a drive letter. Partition and format the drive. This drive should now appear on your system.
