I'd like to know if this drive is Basic or Dynamic in disk management. It seems as though part of the disk was either a simple or spanned volume being controlled by Raid. A simple volume can be extended within the same drive or onto another drive and in these cases you have a Disk Group assigned to the Simple or Spanned Volume. The Disk Group might be part of the issue here.
What you may want to do is try placing the disk in an External USB case and determine if you can view the whole drive. If so, then back up your data
to another drive and reformat the drive in question.
Do no format this drive or any other disk function until you have your data copied to a Known working drive.
The other option is to change the drive from Basic to Dynamic if Disk managment says it's a basic disk.
DO NOT DO THIS until your data is backed up as it may cause data loss or data corruption, neither of
which is desirable.
Another option is to boot your PC, drive installed, to A linux LiveCD and attempt to transfer the data that way to another drive.
You may want to read up about how physical drives are managed by a computer and by an OS to understand what's going on.
